Welcome to the world of the Invert MINI.
The MINI is a modern culmination in the
pursuit of speed, technology, weight
reduction, and overall performance. It
started with radical imaginative
concepts, which in turn inspired years of
research and development, plus
countless hours of testing and
engineering. As a result the MINI
features innovative electronic and
pneumatic technology that challenge the
paradigm that formerly defined “how a
high performance paintball marker
should function”. The patented valve
design, Slip Stream(TM) Solenoid, and
Hall effect Sensor Trigger, set new
standards for marker technology. The
MINI is precision engineered from
aircraft grade aluminum to meet the
demands of the most competitive
players, teams, and climates. The
ultimate intent of the MINI is to exceed
your expectations.

Invert Paintball expects you to play hard
and play frequently and thus the MINI
was built with this in mind. All internal
parts, wear, and contact surfaces have
been heat treated or hard anodized. The
toughest and most resilient materials
and components have been used in the
construction of this marker.

• The MINI uses a single standard
9-volt battery for operation. The
circuitry is a microprocessor based
digital controller.

•

The MINI operates on low-pressure.
The main operating pressure is
180-200 PSI.

The pressure can be
nominally adjusted and monitored
visually via the gauge on the
bottom-line regulator. There is no
secondary regulator to worry about.

• The MINI comes standard with an
accurate lightweight 12” aluminum
barrel that may be removed and
replaced to specifically suit players’
aesthetic and performance desires.

***Read the entire manual before

you prepare your MINI for play. ***

A. OPERATION

Safety and safe marker handling are the
most important aspects of paintball
sports. Please practice each of the
following steps with an unloaded
marker before attempting to charge your
marker with compressed air and
paintballs.

Do not load compressed air and
paintballs into your MINI until you feel
completely confident with your ability to
handle your MINI safely.

Keep your finger out of the trigger guard
and away from the trigger; point the muz­zle of the marker in a safe direction at all
times. Keep the marker turned off until
ready to operate. The MINI uses an on­off switch for one of its safety devices.

Always keep your MINI pointed in a safe
direction. Always use a barrel plug or
barrel-blocking device. Always use
ASTM approved paintball specific eye
protection in any areas where paintball
markers may be discharged. Remember
that the ultimate safety device is you, the
operator.

B. SWITCHING ON YOUR MINI

To switch the MINI on, locate the Power
Button on the back side of the front
fore-grip, in front of the trigger guard
and directly under the LED. Push and
hold the button for 1 second and the LED
light will turn GREEN and then to RED.
Release button and the LED will intermit­tently flash green indicating that the
marker is now ON and LIVE.

C. SWITCHING OFF YOUR MINI

Push and hold the Power Button on the
front fore-grip for 1 second and the LED
will turn solid RED and then to GREEN.
Release button and the MINI will switch
off.

The Invert MINI also has an “Automatic
OFF” feature. If you accidentally leave
your MINI powered up, it will shut itself
off after approximately 1 hour of
inactivity.

www.invertpaintball.com

2. OPERATION

3

The MINI requires a single 9-volt battery
as the electronic power source. The use
of long life batteries is recommended.

The 9-volt battery is located in the front
fore-grip in front of the trigger guard.
The battery is accessed through the
removable left side plate on the front
fore-grip.

Confirm that the marker is OFF. Remove
the screw at the bottom that secures the
left side plate in the front fore–grip. If
there is already a battery in the fore-grip,
gently disconnect the battery from the
battery harness, and then connect a
fresh 9-Volt battery to the harness.
Carefully re-insert battery and harness
back into the battery compartment with
the harness pointed down towards the
bottom of the grip. Make sure that there
are no abrupt kinks and the wires are
comfortably placed, do not force them
into place. Replace the grip panel and
screw.

The MINI also has a Battery Life
indicator. If in standard operation and
the LED flashes with a GREEN color then
the battery is GOOD, if the LED is
ORANGE the battery is fairly depleted
and you should change battery soon, or
if the LED is RED then there is less than
20% of the full battery strength
remaining and battery should be
replaced immediately.

NOTE: Some rechargeable

batteries are too large for the MINI
battery compartment. If they don’t
fit, please don’t force them as this
may damage the gun.

www.invertpaintball.com

3. REPLACING THE 9-VOLT

4

The MINI uses a unique break beam eye
system to determine the absence or
presence of a ball for the purposes of
reduced paint breakage and optimum
rates of fire. The MINI board is pre­programmed to activate the eye system
each time the marker is powered up.

T

o turn the eyes off, ensure that there are
no paintballs in the MINI breach or
feed-neck, make sure the marker is
switched off, and then while pulling and
holding the trigger, turn the marker on.
A quick double blinking green LED will
indicate that the eye system has been
deactivated.

T

o turn the eyes back on, simply turn the
marker completely off and power it up
again without holding the trigger.

A slow consistent single flashing green
LED indicates that the eyes are ON with
no ball in the breach and a rapid
flashing green LED indicates that there
is a ball in the breech.

For optimal performance of the MINI
eyes, keep the inside of the MINI breach
clean and clear of broken paint, paint
residue, or other debris.

Although the eyes can be cleaned via
cleaning the breach of the MINI marker,
if the eyes need to be accessed please
follow the steps outlined in the Main
Body Assembly section of this manual.

www.invertpaintball.com

4. THE MINI EYES OPERATION

5

The MINI is designed to work with

Compressed Air/Nitrogen.

IT DOES NOT WORK WITH CO2.

Consult the place where you purchased
your MINI, or a recognized and
competent airsmith, for instruction in
the safe handling of compressed-air
cylinders before purchasing or
connecting one to your MINI.

The MINI utilizes a fully functional
regulator at the bottom of the grip frame
that doubles as an ASA adaptor or
receiver for a standard threaded pre-set
output compressed air system. It is
strongly recommended that a very high
flow consistent air system is utilized as
an air source for your MINI. There are
several manufacturers of high quality
fixed output compressed air systems.

It is recommended that you use a “low
pressure” (350-450 psi) fixed output
regulator system, although it is
acceptable to use a “high pressure”
fixed output (750-850 psi) system.

If you are using an adjustable output
regulator system the output pressure
should be between 350-450 psi.

Before pressurizing your MINI, check to
make sure that you and anyone within
range are wearing eye protection
designed specifically for paintball.
Double check that the body is screwed
into the frame and the screws are tight­ened. Ensure you have a barrel plug
sock or barrel-blocking device in place
and there are no paintballs in the mark­er. The on-off switch should be OFF. Air
can now be applied, the marker will
become pressurized.

REMEMBER: compressed air or nitrogen
systems can be extremely dangerous if
misused or improperly handled. Use only
cylinders meeting D.O.T. or regionally
defined specifications. Do not perform
any work to your tank or tank regulator.
NEVER disassemble your tank or tank
regulator. Only a qualified and trained
technician should perform work on your
tank and tank regulator.

www.invertpaintball.com

V. COMPRESSED AIR / NITROGEN SUPPLY

6

The MINI comes equipped to accept

1.03" (outer dimension) standard­gravity feed loaders as well as most
agitating and force-feed loaders. Fit the
loader directly into the vertical feed tube.
Always twist it down in a CLOCKWISE
direction.

The MINI uses .68 caliber, water-soluble
paintballs, readily available at paintball
pro-shops, commercial playing fields,
and many sporting goods stores. The
paintballs are fed from the loader
through the direct vertical feed port and
into the breech of the marker.

VII. FIRING THE MINI

Keep your finger out of the trigger guard
and away from the trigger; point the
muzzle of your marker in a safe direction
at all times during this process. Be sure
your goggles are securely in place and
make sure the MINI marker is off. Push
on/off button and hold for over 1 sec
until the Led light changes from Green
to Red

Warning

Always keep your MINI
pointed in a safe direction! Everyone
within firing range should always use
paintball approved eye and face
protection in the presence of live
paintball markers.

• Place the empty loader onto the

marker.

• Be sure that it is securely mounted

in place.

• Apply the compressed gas,

pressurizing the marker.

• Put the paintballs into the loader.

• Remove the barrel plug, sock or

barrel-blocking device.

• Aim the MINI in a safe direction.

• Turn the MINI on: Push the on/off

button for 1 sec until the LED light
changes from solid Green to solid
Red, then release button and LED
should do a slow Green flash.

• Aim the MINI at the target.

• Place your finger on the trigger.

• Pull the trigger with a smooth

squeezing motion.

www.invertpaintball.com

VI. PAINTBALL AND LOADER USAGE

VII. MINI REGULATOR AND VELOCITY ADJUSTMENT

7

***THE MINI BOTTOM-LINE

REGULATOR IS NOT AN ADJUSTABLE

POSITION ASA. To adjust your shooting

position check out the options available from

Invert Paintball.***

The MINI utilizes a fully functional MINI
Bottom-line Regulator at the bottom of
the grip frame that doubles as an ASA
adaptor/receiver for a standard threaded
pre-set output compressed air system.
This unique regulator system channels
air through a chamber in the grip frame
eliminating the need for external macro
line and fittings. The MINI Bottom-line
Regulator controls the amount of air
pressure going from your compressed
air system into the maker itself.

DO NOT USE CO2!!! THE USE OF A

LOW PRESSURE OUTPUT

COMPRESSED AIR SYSTEM IS

STRONGLY SUGGESTED!

Velocity adjustments should be made
via the velocity adjustment allen screw.

NOT THE BOTTOMLINE

REGULATOR CAP.

THE MINI BOTTOM-LINE REGULATOR
IS PRE-SET AND LOCKED FROM THE
FACTORY AND SHOULD NOT BE
DISASSEMBLED.

The MINI regulator
should be pre-set at 200 PSI as this is
the best operating pressure for firing the
marker. However, if over time you do
need to adjust the pressure only use the
Regulator Adjuster Screw on the front of
your MINI Bottom-line Regulator.
Tightening the Adjustment screw
increases the pressure, which can be
monitored via the Bottom-line Regulator
Gauge. The MINI will operate with less
than 200 psi going into it, but YOU
SHOULD NEVER RUN IT AT MORE
THAN 200 PSI! Once you set the MINI
Bottom-line regulator at 200 PSI, then
you can make your velocity adjustments
at the bolt guide cap at the rear of the
main body.

www.invertpaintball.com

8

The following directions are not for
adjusting the Bottom-line regulator.
They are only to be followed in the event
the bottom-line regulator has come
apart or the cap has been removed. First
loosen the small set screw on the
bottom of the regulator that locks the
Regulator Cap in place. At the front side
of the bottom-line regulator there is a
Regulator Cap and a Regulator Adjuster
screw inside of that cap. In the case that
the Regulator Cap becomes loose, do
not use tools, use your hand strength
only. Back out the brass adjuster
completely with the correct allen wrench
then screw the cap in by hand until you
feel resistance (with gun gassed up)
then back it out a 1/8 turn.

DO NOT OVERTIGHTEN THE

REGULATOR CAP! OVER

PRESSURIZING CAN DO SERIOUS

DAMAGE TO YOUR MINI!

Once this adjustment has been made,
retighten the locking set screw then
screw in the brass adjuster to set the
pressure.

Do not attempt to adjust the physical
position of the MINI Bottom-line
Regulator! Invert Paintball
manufactures alternate designs of the
MINI Bottom-line Regulator to achieve
alternate shooting positions.

Please see your local paintball

Pro-Shop for or call Invert Paintball or

Paintball Solutions for more

information.

www.invertpaintball.com

9

At the back of the MINI main body is the
Bolt Guide Cap. The allen screw in the
bolt guide cap serves as your velocity
adjuster. Confirm that the pressure on
your MINI Bottom-line Regulator is at
200 PSI. Then you can increase or
decrease the velocity on your MINI by
tightening or loosening the velocity
adjustment screw, with a 1/4 inch Allen
wrench.

• TO INCREASE YOUR VELOCITY –

Unscrew or loosen the velocity
adjustment screw by turning it counter
clockwise. Rotate the velocity
adjustment screw counter-clockwise in
small increments (1/4 turn or less),
stopping between slight turns to test
velocity, until desired velocity is
achieved. Do not back the adjuster out
passed being flush. Stop if you hear an
air leak, and adjust back in a 1/4 turn. A
paintball specific radar chronograph
should be used to accurately measure
your velocity.

•

TO DECREASE YOUR VELOCITY –

Tighten or screw-in the velocity
adjustment screw by turning it
clockwise. Rotate the velocity
adjustment screw clockwise in small
increments (1/4 turn or less), stopping
between slight turns to test velocity,
until desired velocity is achieved. A
paintball specific radar chronograph
should be used to accurately measure
your velocity.

This marker was designed with safety
and safety standards in mind. If you
attempt to shoot paintballs at a higher
velocity than established safety
standards, the marker may not function
properly.

NOTE 1! If you attempt to operate the
marker at extremely high velocities, the
internals will not function properly!

NOTE 2! This gun is not designed to shoot
above the safety limits established by
industry standards but under certain
conditions it may. It is therefore important

www.invertpaintball.com

ADJUSTING THE VELOCITY

10

to check the velocity each time before
playing with your MINI.

NOTE 3! Higher pressures DO NOT equate
to better performance and higher velocities.
High pressures in this marker will cause
problems, showing up in erratic velocity,
extreme gas consumption, leaks, and
general poor performance.

The Invert MINI is driven by a Optimus
I™ Board. The Optimus I™ Board
features several modes and functions
that are listed below. The Optimus I™
Board is located inside the front
fore-grip.

VIX. FUNCTIONS ,MODES

Before adjusting firing modes, rate of

fire or dwell, always remove

propellant source from the MINI and

install barrel blocking device.

The Optimus I™ Board inside your MINI
features 5 functions. It uses a 3 color
LED indicator on the backside of the
front fore-grip to indicate functions and
modes during live play and during
programming.

To access and set the Optimus I™
Board, place MINI on a flat surface with
muzzle pointing to the left. Using a
5/64” hex wrench, remove the screw that
secures the left side plate in the front
fore–grip. This will expose the battery
and the Optimus I™ Board. Please
locate the (A) Function Key, which is a
small black button on the rear of the
board, to the left and slightly above the
Power Button (B), marked DIP (see
illustration). It is not neccesary to
remove the board from the housing in
order to manage settings.

www.invertpaintball.com

VIX. BOARD DESCRIPTION

The MINI must be OFF to begin
managing functions.

While the MINI
is OFF press the Function Key to access
one of the 5 different functions and make
adjustments. For example, press the
Function Key 1 time and you will be in
“Function 1” which is “Firing Modes” or
press the Function Key 3 times and you
will be in “Function 3” which is “Dwell”.

1. Firing Modes (Solid Red LED)

2. Rate of Fire (Solid Green LED)

3. Dwell (Solid Orange LED)

4. BIP Delay (Flashing Red LED)

5. Ramping Point (Quick-Flashing

Green LED)

Once you push the Function Key the
appropriate amount of times to get into
the desired function, the LED will flash a
specific color per the descriptions below
followed by flashing which will indicate
the current setting in that function. To
change settings in each function, you
use both the Power Button and Function
Key, to shift up or down much like
shifting through motorcycle gears. To
increase the number in that setting, hit
the Function Key. To decrease the
number in that setting hit the Power
Button.

Function Key for up –

Power Button for down.

VIX. FUNCTIONS ,MODES

12

1. Firing Modes –

WILL BE INDICATED BY SOLID RED LED

To get into the Firing Mode Function,
make sure the POWER IS OFF, then push
the Function Key one time and LED will
turn to Red and then flash to indicate the
Firing Mode that it is currently in. For
example the Default mode is Semi-Auto
which will be demonstrated by one
flash. There are 4 Firing Modes:

a. Semi-Auto/NPPL (1 Flash)

– one shot per trigger pull. Max ROF 20

BPS

b. Ramping/PSP (2 Flashes)

– First 3 shots will be standard

semi-auto, on 4th shot, MINI will ramp
to a pre-set 15 BPS ROF.

c. Full-Auto/NXL (3 Flashes)

– First 3 shots will be standard Semi-

auto, on 4th shot MINI will go into
full auto mode with a pre-set 15 BPS
ROF.

d. Ramping/Millen. (4 Flashes)

– the MINI will operate in a semi-auto

mode until player achieves an 8 BPS
trigger pull. At that point, and as
long as 8 trigger pulls per second
are maintained, the MINI will ramp to
a pre-set 15 BPS ROF.

To cycle through these modes you use
both the Power Button and Function
Key. Once you push the Function Key
one time to get into the Firing Modes the
LED will flash red. While the LED is lit
Red push the Function Key to cycle up
(from 1 for Semi to 4 for Full Auto) and
to go the opposite direction (from 4 at
Full Auto through to 1 for Semi) use the
Power Button to cycle down.

For example, if you are in the Default Semi-Auto
mode and want to go to 3 Shot Burst, Push the
Function Key twice while the LED is lit Red.
Upon release you should see the LED flash red
3 times. To move from 3 Shot Burst to 2 Shot
Burst, push the Function One time to get into
firing modes, then while LED is lit Red, push
Power Button one time and release. LED should
flash Red two times to indicate that you are now
in Firing Mode 2 – 2 shot burst.

www.invertpaintball.com

2. Max Rate-of-Fire –

WILL BE INDICATED BY SOLID GREEN LED

To get into the ROF Function, make sure
POWER IS OFF, then push Function Key
two times and LED will turn to Green
and then flash to indicate the Rate Of
Fire (1-20) that you are currently using.
Default is 15 Balls Per Second. To adjust
ROF push the Function Key two times
and when the LED is lit Green use either
the Function Key (to toggle up or
increase your ROF) or the Power Button
(to decrease the ROF). For example – To
start you will be in a Default setting of 15
BPS. Push the Function Key twice to get
into ROF Mode. While the LED is lit
Green, press the Function Key 5 times to
take you to 20 BPS. Upon releasing the
Function Key, the LED should then blink
20 times indicating your new Rate Of
Fire.

The easy way to know your rate of fire:
number of flashes divided by two then
add ten. eg 15 flashes / 2 = 7.5

7.5 + 10 = 17.5 BPS

WILL BE INDICATED BY SOLID ORANGE LED

To get into the Dwell Function, make
sure the POWER IS OFF, then push the
Function Key three times and the LED
will turn to Orange and then flash to
indicate the Dwell Setting that you are
currently at. The MINI Dwell Setting is
Defaulted at setting 38 (which is 38 x
.25 milliseconds). Dwell is adjustable
from 1 to 45. This Function is also
controlled through the same techniques
used for Firing Modes and ROF
Functions, while the LED is lit ORANGE,
to increase or decrease your Dwell by
increments of .25 milliseconds.

4. BIP (Ball In Place) Delay –

WILL BE INDICATED BY A QUICK
FLASHING RED LED

To get into the BIP Function, make sure
the POWER IS OFF, then push the
Function Key 4 times. The LED will
quickly flash red to indicate that you are
in the BIP Function. Then the LED will
pulse / slowly flash to indicate the BIP
Setting that you are currently using.

Default is (1) One Pulse (1 millisecond).
BIP is adjustable from 1 to 40
milliseconds. This Function is also
controlled through the same techniques
used for Firing Modes and ROF
Functions (while the LED is Red) to
increase or decrease your BIP in 1
milliseconds increments.

5. Ramping Point –

WILL BE INDICATED BY QUICK
FLASHING GREEN LED

To get into the Ramping Point function
make sure the power is OFF, then push
the Function button 5 times and the LED
will turn to a quickly flashing green and

XII. UNLOADING THE MINI

17

The MINI features a Hall Effect Sensor
Trigger. There is no trigger switch to
worry about, clog with paint, or break.

You will notice three (3) screws in your
trigger. The screw on the face of the
trigger adjusts your rear movement
range and stop point. The rear top
screw adjusts forward movement and
stop point. The front top screw adjusts
your trigger activation point.

Use blue loctite while adjusting the
screws. Normal activity can cause the
screws to back out of adjustment. DO
NOT glob the loctite on. Make your
adjustments Very Carefully. Clean up
any excess loctite and let it dry for at
least an hour before using your
MINI.This ensures the screws will
remain in place.

www.invertpaintball.com

XXI. ADJUSTING THE TRIGGER PULL

18

CAUTION: Before attempting to
perform any maintenance operations
or any marker disassembly, make sure
that all paintballs and propellant
sources have been removed from the
marker. Install a barrel blocking
device, push on/off button and hold for
over 1 sec until the Led light changes
from Red to Green, and keep the
marker powered OFF.

Simple Maintenance

Keep your MINI clean and lubricated to
eliminate the friction that would prevent
reliable operation. Clean and lube the
marker before each use, and do not put
it away dirty. USE NO OILS! Do not use
oils made for paintball markers, real
firearms or pneumatic tools, do not use
oils at all. Do NOT use petroleum-based
lubricants in the lubrication of this
marker. Teflon or silicon (NON-spray
only) lubricants may be used for
lubrication for the bolt area only of the
main housing. paintball recommended
grease such as Dow 33 is recommended

for lubricating the regulator pistons and

paintball recommended Grease and not
axel grease.

Ball Detents

The MINI ball detents are located on
either side of the main breech, directly
beneath the feedneck and secured under
the MINI ball detent covers.

Bolt Guide Lubrication

When you feel a performace drop off the only
real maintenance needed is the bolt and bolt
guide lubrication.

Remove the rear grip frame screw to
release the bolt and bolt guide assembly.
Clean all dirt and old grease from the
spring, bolt and bolt guide. On the bolt
guide there are six o-ring that need to be
lightly lubricated with Dow 33. Also
lubricate the two rear o-rings on the bolt
and lightly lubricate the o-ring at the bolt
tip.

XIV. MAINTENANCE

19

The MINI ball detents are designed for
extended use and should not need
replacing for long periods. If they do
need replacing, simply unscrew the ball
detent covers on both side of the
marker’s main body, remove the old ball
detents, replace with new ball detents,
and replace the ball detent covers
making sure to NOT over-tighten screws.

Cleaning Paint from the Barrel

Unscrew the barrel to remove the barrel
for swabbing/cleaning. Keep the barrel
clean to insure the continued accuracy
of the MINI. Gelatin from the paintballs
has a tendency to build up in the barrel.
As part of your cleaning ritual, wash out
the barrel with hot soapy water and rinse
it well.

XIV. MAINTENANCE

20

CAUTION: Before attempting to
perform any maintenance operations
or any marker disassembly, make sure
that all paintballs and propellant
sources have been removed from the
marker. Install a barrel blocking
device, push on/off button and hold for
over 1 sec until the Led light changes
from Red to Green, and keep the MINI
power OFF.

The front fore-grip of the MINI is the
housing for the Optimus I™ Board and
the battery. You only need to loosen two
screws to remove the front fore-grip

from the main body, however this is not
necessary or recommended. There is an
easy access removable side plate which
gives you access to the Optimus I™
Board, Function Key, Battery. To access
it simply remove the screw at the bottom
of the fore grip and remove the plate.
There is very little need to ever remove
the Front Fore-Grip from the Frame.

PLEASE USE CAUTION!

If you remove and re-install the Front
Fore-Grip. The male portion of the board
connector is located on the Optimus I™
board and is guided into the female
connection point located on the Sensor
board (which is housed in the main
body). This can be very fragile, so
please be gentle. Likewise there is a
small groove in the bottom of the
battery/board compartment to make sure
the alignment of the board is accurate in
re-assembly. Ensure that the Front
Fore-Grip is secured on the trigger
guard guide, when reinstalling onto
the Frame.

DO NOT over tighten retention screw!

and keep the MINI power OFF Insert
Image of Grip Frame and Regulator

The Grip Frame houses the trigger, and
the air channel (which feeds air from the
MINI Bottom-line Regulator into the
main body). Attached to the bottom of
the grip frame is the MINI Bottom-line
Regulator. The MINI Bottom-line
Regulator is a functioning regulator and
cannot be adjusted forward or
backwards without MINI approved
aftermarket parts.

To access the bottom-line regulator first
remove the grip panels using a hex
wrench. Next loosen the outside set
screws located on the outside lower end
of the grip frame. The outside set
screws only need to come out enough to
loosen the bottom regulator so it can be
pulled down from the MINI.

When reattaching the bottom-line
regulator, put the piece back into the
grip frame and first tighten the outside
set screws so that they are flush to the
grip frame. If the bottom-line regulator
is not tight enough turn the MINI over to
access the inside set screws in the grip
frame. Tighten inside set screws just
until tight. Do not over tighten any set
screws in the MINI.

CAUTION: Before attempting to

perform any maintenance operations

or any marker disassembly, make
sure that all paintballs and propellant
sources have been removed from the

marker. Install a barrel blocking

device, push the on/off button and
hold for over 1 sec until the Led light

changes from Red to Green, and keep

the MINI power OFF

The main body consists of the Air
Transfer Plate, the Check Valve, the
Sensor board (which the eyes are
attached to), the Main Spring, and the
Bolt Assembly. The Bolt Assembly can
be accessed by loosening the rear main
body screw (Primary Retention Screw)
so that the internals pop out the back of
the MINI.

To access the eyes, the main body must
be separated from the grip frame. This
must be done in the following order:

1.

Using a hex wrench, remove the two
set screws accessible through the front
of the trigger guard allowing the front
foregrip assembly to slide down the
attachment rail and away from the main
body.

2.

After the front foregrip assembly is
removed, remove the two main body
screws.

3.

Slide the Grip Frame Assembly away
from the main body. Do NOT twist while
separating.
The Sensor Board is located under the
Air Transfer Plate in the bottom of the
main body, which is fastened with 7
small Hex head screws.

PLEASE USE CAUTION WHEN

REMOVING THE SENSOR BOARD – IF

THE CHECK VALVE IS ACCIDENTALLY

REMOVED IT WILL AFFECT THE

PERFORMANCE OF THE MARKER!

The Check Valve is a very small plastic
piece located between the body and the
Sensor Board. It is designed to control
the bolt speed of the marker, but due to
its size may be easy to misplace. If it is
misplaced the MINI will fire, but the bolt
speed will increase drastically and likely
cause problems. To re-insert the Check
Valve, insert it with the “crown side” in
first, back into it’s spot on the main
body.

To re-attach the Grip Frame and Front
Foregrip to the main body:

1.

Line up the solenoid and gas

transfer tube attached to the body with
the space and the tube in the grip frame.

2.

Slide Grip Frame into place

3.

Insert two main body screws and

tighten (do NOT over tighten).

4.

Slide Front Foregrip Assembly up

the rail located on the front of the trigger
guard and carefully press upwards while
making sure the circuit board
connectors line up and are properly
seated.

5.

Using a hex wrench, install the two

set screws accessible through the front
of the trigger guard holding the front
foregrip assembly to the attachment rail
(do NOT over tighten).

The technology in the MINI Sensor
board and Eyes eliminate the need for
wires. The Eyes are an integrated fixed
part of the circuit board. To remove the
eyes you will need to remove the Sensor
board, however it is recommended that
the eyes should be cleaned via the
breach with a clean cloth, cotton swab,
or swab style squeegee.

The main body and the grip frame are
held together with a front and a back
body screw (Primary Retention Screw)
both 1/8 Hex Key. Use caution when
unscrewing the Primary Retention screw
as the bolt and spring will pop out the
back of the Mini. Remove the Primary
Retention Screw at the back of the gun
directly behind the grip frame and on the
underside of the main body. By loosen­ing and removing this screw, the pres­sure of the Main Spring will push the
Main Body Internals out of the back of
the marker, so please keep a firm grip on
the Rear Body Cap!

NOTE – The main spring must be fitted
to the bolt and does so in ONLY ONE
DIRECTION. The Main Spring is
actually slightly tapered or conical, so
when the spring is slid onto the bolt
correctly, there will be a snug fit and
most importantly when pressed firmly,
it will actually “click” into place
against the rear of the bolt. Adversely
if you attempt to slide the spring onto
the bolt the wrong way, the fit will be
loose and will not “click” into place.

To re-assemble the Main Body, insert
the Main Spring and Bolt Assembly into
the body with the Spring towards the
front of the marker, gently compress the
Main Spring by pushing in the
components towards the front of the
marker, line up the Rear Body Cap, then
re-insert the Primary Retention Screw.

TO LINE UP THE REAR OF THE BOLT
GUIDE ON THE BODY –

There is a small
hole on the back of the Bolt Guide that
should be lined up to match the small
hole on the back of the body which is at
the top dead center of the body.

Tighten both body screws without over
tightening either screw.

Ball Breakage Problems

The balls break in the breach.

• The balls in you loader can bind,
messing up your trigger timing.
Always use an agitated or powerfeed
loader and verify the eyes are on.

• If the ball detents do not move freely,
the paintballs may crush against them
or they may have stuck in the
depressed position, allowing double
feeding. Check tension regularly and
keep this area as clean as
possible.

• If the ball detents are too sloppy, the
ball will not be held in the proper
position. This may allow the next ball
to enter the path of the bolt,
subjecting it to impact cracking or
shearing. Verify the tension.

Regulator Related Problems

The gauge reads correctly when charged,
but climbs in pressure after a few
moments.

• The regulator seal has been
contaminated. Disassemble the
regulator and clean the seal with a Q-

tip and alcohol or back out the
adjuster screw completely and check
that the pressure is zero. If not back
out the reg cap until it reads zero then
adjust te pressure to 200psi with the
brass adjuster only. If you need
assistance in the disassembly of the
regulator, please go to www.paintball­solutions.com or call 1-800-220-

3222.

Battery Related Problems

• LED Functions but the marker does
not fire.

• LED flashes either Orange or Red
during normal operation.

• Alternately missed shots.

• Velocity drops while firing several
shots.

• Erratic velocities. Jumps of 20 fps or
more.

• Unexplainable paint breakage.

• Solution:

Change the Battery. All
batteries are NOT created equal.
Performance will vary. Therefore, if
you experience any erratic behavior,
always use a new battery.
