degassed, hopper
removed, no paintballs in the feed port
or breech and the EGrip is turned off.
2. While pointing marker
in a safe direction,
place the threaded
end of the barrel into the front opening of the marker body.
3. Turn the barrel clockwise until it stops (do not over tighten).
4. Adjust the barrel accessories if necessary.
5. Install a barrel blocking device. This can be a barrel plug or other such device that
prevents the accidental discharge of a paintball.
Air Cylinder Installation
1. Make sure the barrel blocking device is properly installed and the E-grip is turned
off.
2. While pointing the marker in a safe direction, cock the marker by pulling the cock-
ing knob located on the left side of the marker back until it clicks and stops.
3. Release the cocking knob.

draw the cylinder into the marker until it stops. Your marker is now charged.
Note: If cylinder is installed incorrectly, you can damage the threads on your marker
and cylinder. Make sure to align them properly before installing cylinder.
Velocity Adjustment
1. Always check the velocity of the marker
prior to playing paintball. Different playing fields may have different maximum
velocity limits. At no time should you
shoot at velocities above 300 feet-persecond.
2. Put on eye protection designed specifically for paintball and make sure that
anyone within range of the BT Delta
Elite™ does the same.
3. While pointing the marker in a safe direction, remove the barrel blocking device.
4. Point the BT Delta Elite™ over a chronograph that will measure the velocity of the
paintballs discharged by the marker.
5. Turn the Marker’s E-Grip On.
6. Pull the trigger and check the reading on the chronograph.
7. Locate the velocity adjuster screw on the center of BT Delta Elite™, under the
name Plate.
8. Using a 5/32" hex key, turn the screw inward or clockwise to reduce the velocity,
and outward or counterclockwise to increase the velocity of the paintballs discharged from the marker.
Note: Different Types/Brands of Paintballs will affect your markers velocity. Check
your markers velocity before each day of
play.
Stock Adjustment
1. Push the stock adjustment lever to the
left and adjust the stocks length by pulling
or pushing on the back of the stock
2. Make sure the lever springs back to the
right to lock it in position.

(Figures 6-8)
Figure 6Figure 7Figure 8
Activating the Rip-Clip™
Locate the power button on the rear control panel. To turn on, press the button. The
green LED comes on while the button is pressed; now release button. The green
LED will now flash again for one second, go off, then flash quickly 1, 2, or 3 times
indicating the speed it is currently set to. The motor will spin for a second and the
loader is now ready to use. Do NOT fire your marker until after the initial motor spin
has completed. Firing during this period can disrupt the auto-adjusting sound sensitivity and cause the hopper not to work properly. The green LED will flash repeatedly
while the unit is on to show it is ready. If the LED flashing changes to red, then the
batteries are low and need to be replaced.
Battery Installation
1. Remove the screw on top of battery door.
2. Install 4 x AA batteries following the polarity marking.
3. Reinstall the battery door screw. (Figure 1)
Rip-Clip Installation
1. Loosen up the spring screws. (Figure 2)
2. Clip on the BT Delta Elite™ between the 2 sight rails.
(Figure 3)
3. Make sure the feed holes are aligned. (Figure 4)
4. Tighten up the spring screws. (Figure 5)
Figure 2Figure 3Figure 4
Figure 1
Figure 5
To turn off, press and hold until the loader gives a RED indication. Release the button and loader will power down to the OFF state.
Setting the Speed
1. When the Rip-Clip is first turned on, while the LED flashes for one long second,
press and hold the power button again during this flash.
2. When done properly, the LED will now change to red and you can release the button.
3. The LED will only stay red for about 15 seconds, then change back to its flashing
green sequence for regular operation if no buttons are pressed.
4. To set the speed during the red LED phase, push and release the button the number of times necessary based on what speed you desire.
5. Press once for normal slow speed, twice for faster normal speed, and three times
for fastest speed. Each time you press and release the button during this sequence,
the press of the button should last about one second.
6. If done too quickly, the board may not be set to the speed you desire. When done
correctly, the red LED will go off, then flash the same number of times the button
was pressed, indicating which speed it is now set to.
7. The motor will now spin up at the speed it is set to, it will stop, and now the speed
is set and the unit is ready to use.
Note: Always use good name brand batteries. Using other types of batteries will
affect the Rip Clips performance.

The Apex barrel is the most advanced barrel in
the world. You can adjust the barrel to shoot in
different directions and set it to give you greater
distance than any standard barrel.

modes are changed by removing the left
side grip and adjusting the dip switches
located in the grip frame. The Delta Elite
comes in Ramping mode from the factory
and the Jumper in the frame must be
removed to lock the firing mode to semiauto. The E-Grip has an automatic shut-off
after 1 hour of inactivity.
Note: Always use good name brand batteries. Using other types of batteries will
affect the marker performance.
Adjusting Direction of Shots
1. Adjust the Apex front by turning it.
2. Turning it right will give you a right hook
3. Turning it left will give you a left hook
4. Rotating it 180 degrees will give you a drop shot.
5. The standard position will give you a long shot.
Note: It will be necessary to adjust the Ramp setting on the Apex barrel to the paint
you are using. Different brands/types of paintballs will have a slightly different size.
This will affect the amount of curve you get.
Features
1. On/Off capability.
2. Hit previously untouchable targets with new curve feature.
3. Adjustable ramp switch - choose the desired level of the curve.
4. Left hook, right hook, drop shot and long flat trajectory shots with a twist of the
barrel.
5. Easy to dial in targets and change the level of curve.

Adjusting the Sear Height
To adjust the sear height, there is a set
screw in the lower vertical arm of the sear
that contacts the front of the solenoid. If it
is necessary to raise the sear to engage
the rear bolt, insert a 0.50" allen wrench
past the side of trigger and turn the allen
wrench counter clockwise. Make adjustments while the trigger frame is off the
receiver (body) and the marker is
degassed. Look down from the top of
frame to help locate the set screw. Only
turn the allen wrench 1/8 turn at a time and check engagement after each adjustment. Once the sear begins to engage the rear bolt, turn the set screw an additional
half to 1 full turn.
General Maintenance
Once the BT Delta is unloaded and the air cylinder is removed, you can use a damp
cloth to wipe off paint, oil, dirt and debris. You can also use warm water to rinse the
marker clean, but be careful not to get the internal components wet.
Once your marker is clean and dry you can re-oil using a light, premium marker oil.
(Note: Petroleum based and aerosol products can damage your markers o-rings.
