Safety Guidelines

Quad-300

Barnett Quad-300 crossbows are equipped with an automatic
safety, which engages every time the crossbow is cocked. The
safety must be released before each shot. This, as with any
other mechanical device, does not guarantee total safety, as no
safety device is a substitute for common sense and safe
handling. The crossbow trigger is only to be pulled when the
safety is in "fire" position and NEVER when it is in the "safe"
position or anywhere between "safe" and "fire." Do not attempt
to alter or modify the safety or the trigger mechanism. If the
safety will not release, this happens when the trigger is pulled
before the safety switch is released. To correct this, push the
trigger pull forward, then release the safety catch.

The following rules should be followed at all times:

EXTREME CAUTION SHOULD BE USED AT ALL TIMES WHEN
HANDLING A CROSSBOW. FAILURE TO FOLLOW THESE
RULES COULD RESULT IN SERIOUS INJURY OR DEATH.

• Always keep your fingers below the flight track and
out of the path of cables and strings when firing the
crossbow.

• Never dry-fire the crossbow (shoot without an
arrow). Dry firing will void the warranty and can
result in damage to the limb assembly and possibly
cause personal injury.

• Never fire the crossbow until you are sure of your
target.

• Always use an adequate target and backstop when
target shooting.

• Always use suitable crossbow arrows, such as
XX75 2219 20” or Barnett’s 22" Carbon Crossbow
arrows for the Quad-300 with moon nock. Arrows
of improper stiffness or mass weight may damage
the limb and cable assembly, voiding the warranty
and possibly cause personal injury.

• Always inspect the crossbow and arrows before
firing. Bent or damaged arrows are not safe to fire
and should be discarded or repaired.

ASSEMBLY GUIDE

Attaching Prod Housing to Stock

PRIOR TO ASSEMBLY LUBRICATE CABLES (CENTER) WHERE
THEY ARE IN CONTACT WITH THE UNDERSIDE OF FLIGHT
TRACK.

1. Place the string on top of the flight track while sliding
cables into long U-shaped channel. See Figure 1

2. Push bow limb assembly gently until it engages with the
stock.

3. Secure the bow limb assembly to the stock using the
1/4"-20x3/4" screw and washer with the 3/16" hex key.
See Figure 2

Fig.1

Fig. 2

Attaching the Foot Stirrup Assembly

1. Attach the foot stirrup assembly to the front of limb
housing using the 5/16"- 18x1-1/2" button head screw.
Make sure foot stirrup is pushed into foot stirrup block as
far as it will go before

putting the 5/16"-18x1-1/2" button

head screw into foot stirrup block and attach.

2. Align the foot stirrup assembly
to limb housing so that foot
claw is positioned on bottom of
block. See Figure 3

3. For your own safety, before

Fig.3

each shooting, make sure that
the foot stirrup assembly is fully tightened to the limb
housing.

Mounting the Front Sight

1. Install the front sight bracket using the two
lock washers and 10-32x3/4" socket head
provided. See Figure 4

Fig. 4

8

2. Unscrewing the threaded lock nut from the
pin and inserting it through the side of the

Fig. 5

front sight so that the point of the pin is in
the center of the front sight. See Figure 5

3. Replace threaded lock nut on sight pin and
tighten.

Mounting the Rear Peep Sight

1. Slide the rear peep sight onto the attached dovetail with
setscrew facing the front of the bow.

2. Tighten setscrew when the peep is in
the proper eye relief position with the
hex key provided. See Figure 6

Fig. 6

Installing an Optional Scope

The recommended crossbow scope is a Barnett 4x32 mm five
reticle scope which includes 1” rings to fit a 3/8” dovetail mount.

1.) Remove peep sight from the scope rail.

2.) Position your scope by moving it forward or backward
until the proper eye relief is found. This is typically three
to four inches from your eye to the eye-piece when you
are holding the crossbow in a shooting position.

3.) After scope installed you may remove the front sight
bracket and pins.

Important: Be sure to tighten scope mount rings before shooting
crossbow.

CROSSBOW OPERATION

Cocking your Crossbow

Be sure to apply Barnett lubewax to the center string
serving, cables and the flight track area from the string to
the trigger area.

1.) Place the foot stirrup on the ground with one foot in the
stirrup and the stock resting against your mid section.
See Figure 7

2.) Place both hands on the string at each side of the
crossbow body no more than ½ inch from crossbow body.

3.) Using even pressure pull the string back until it locks into

the trigger mechanism with an
audible “click”. Be sure to apply
downward pressure against
flight track.

4.) Slowly release hand

pressure on the string until you

Fig. 7

9

are sure it is locked securely into the trigger mechanism. The
crossbow is now cocked with the safety on.

Note: The serving on the string has had a line on each side of
the flight surface marked at the factory. After cocking the
crossbow make sure that the marks on the string are showing
equally on each side of the trigger mechanism. Unevenly cocked
crossbows will have erratic arrow flight. When restringing your
crossbow mark the serving of the string, on each side of the
flight track at rest, where the string leaves the flight surface
(track) and apply Barnett Lubewax to the string serving and
track surface.

Arrow Retainer

When loaded, the arrow should lie “flat” in the flight grove. The
arrow retaining spring should not be twisted to the left or right
and should exert only enough pressure on the rear of the arrow
to hold it in place. It should not lift the front of the arrow off the
flight grove. At this point, the arrow should be lying directly
parallel with the flight grove. We recommend the use of Barnett
arrows manufactured specifically for your Barnett crossbow.

Loading your Crossbow

1.) Place the arrow forward under the front sight bracket and lay the
arrow on the flight surface. When using arrows with moon

nocks, be sure that the odd colored fletch is placed in the
flight grove and that the concaved nock is parallel to the
string.

2.) Slide the arrow back under the arrow retaining spring and
fully into the trigger mechanism. Note: The arrow

retaining spring should only exert enough pressure to
hold the arrow in place without lifting it from its position
on the flight surface.

Firing your Crossbow

To fire the arrow from your crossbow:

1.) Point the crossbow in a safe direction.

2.) Slide the safety forward to the off position. The

crossbow will now fire when the trigger is pulled. The
safety MUST be disengaged in this manner prior to
every shot. BE SURE TO KEEP YOUR FINGERS BELOW THE

STOCK FORE END (FLIGHT TRACK) WHILE SHOOTING. Note
photos below

10

INCORRECT

INCORRECT

This will prevent your hands from being struck by the
string as it travels forward. The velocity of the string
hitting your fingers will cause severe injury.

Unloading your Crossbow

By far, the easiest way to un-cock a cocked crossbow is to fire an
arrow into a target or into the ground away from debris, loose
rocks or other people.

Sighting-In the Crossbow
Using the rear peep sight and front sight pins:

1.) Place the first sight pin near the top of the front sight
bracket.

2.) Shooting at a target from 10 yards, aim for the bulls eye. If
the first shot is above the bulls eye, move the pin up (or down if
the shot is below the bulls eye).

3.) If the first shot is to the left of the bulls eye, screw the pin to
the left (or right if the shot is to the right)

TIP: Move the pin in the direction of the error, follow the arrow.
Continue in this manner until you have three consecutive shots
into the bulls eye. Repeat this procedure with the other pin,
starting near the bottom of the sight bracket. It is

recommended that the bottom pin be sighted in to the 30- to 35­yard range.

CORRECT CORRECT

11

Arrow Selection and Proper Flight

Due to the unique design of your Barnett crossbow, it is
imperative that only specified arrows are used. These arrows
are correctly weighted to absorb the high energy generated by
the compound design. Lighter arrows simulate a “dryfire”
condition and will result in damage to the crossbow VOIDING the
warranty. Barnett’s 22” Carbon Arrows or XX75 20” 2219 are
correctly “spined”. DRY FIRING WILL VOID THE WARRANTY.

• Use Barnett’s 22” Carbon Arrows or 20” 2219 XX75
Arrows with straight, offset or helical fletches with or
Moon Nock.

• Recommended fixed blade broadheads can be any three
blade low profile broadhead with a cutting diameter no
larger than 1-3/16”.

• When using fixed blade broadheads, the blades must be
aligned with the fletches of the arrow. This can be done
by placing a rubber o-ring between the broadhead and
the arrow front insert.

• Mechanical broadheads that simulate the flight of a field
point may be used where legal.

IMPORTANT DISCLAIMER

Because of the power of the Barnett Crossbow and the
inconsistent properties of wooden shafts, which have a tendency
to warp, vary in spine stiffness; density; moisture absorption, all
of which result in inaccuracy. Barnett International DOES NOT
RECOMMEND their use under any circumstance.
Possible injury could result from shaft breakage, ect., we accept
no responsibility or liability arising from the use of wooded shaft
arrows.

TROUBLESHOOTING

Arrow Flight

Possibly the greatest variable in accuracy are the arrows. These
differ greatly and have totally different fight characteristics.
Generally speaking, target arrows are more accurate than
hunting arrows. Because of the surface area of the fixed bladed
broadheads used in hunting there is a tendency for the arrow to
“plane”. To help overcome this we suggest that practice be made
well in advance of the hunting season with the type of arrows

12

you will be using to achieve consistent groupings. Consider the
following when selecting arrows; heavy, stiff spined arrows with
fletching hold more energy for humane harvesting at reasonable
ranges (15-35 yards). Lighter arrows are much faster however
hold less energy.

1. If the string has been changed was it a Barnett string?

2. Are the arrows straight and fletches (vanes) in good
condition?

3. Does the arrow lie flat (true) on the flight groove? Is the
arrow retainer to tight or twisted? (Adjust arrow retainer
with a pair of needle nose pliers – USE CAUTION)

4. Does the arrow slide smoothly and evenly into the trigger
mechanism?

5. When cocking your crossbow, are you pulling equally on
each side on each side of the string? (Mark your new
strings on each side of the flight track as stated earlier)
After cocking the crossbow, make sure the marks are
showing evenly on each side of the trigger mechanism.

6. When cocking your crossbow make a conscious effort to
hold the string on the flight track so as not to lift over the
arrow retainer.

7. Are you putting one fletching down in the flight groove?

8. When using broadheads, line up
the blades with the fletches on the
arrow (using o-ring).

9. Have you checked the tiller to see
if any adjustments should be
made? See Figure 8 Tiller is the
measurement between the base of
the limb and the bowstring. The tiller measurement tells
you if both limbs are equally stressed. Your bow is in
proper tiller when this measurement is the same for both
limbs. Uneven tiller will cause erratic arrow flight. All

crossbows are accurately tillered at the factory
prior to shipping. To adjust the tiller, use an allen

wrench and measuring tape as shown in the illustration.

String Fraying

1. Are you using Barnett lubewax on the center string
serving and cables every 5-10 shots and on the flight
track when needed?

2. Keep the trigger mechanism and flight surface free of
obstruction.

Fig. 3

Fig. 8

13

3. Check for metal burrs on the flight track and arrow end
caps.

Limbs Weak or Losing Power

1. Has the crossbow been dry fired? (could cause limb to
crack).

2. Inspect the limbs for splits or cracks.

3. Are you using Barnett string (the proper length).

CARE AND MAINTENANCE

Care of String

The owners kit contains a tube of lube wax that should be
applied to the center serving and flight track every 5 – 10 shots.
Lube wax should also be applied anywhere the cables make
contact with the Teflon tape or flight track every 20 – 30 shots.
To extend the life of your cables it is important to apply
ARCHERY STRING WAX to all areas of the cables and string every
30 - 50 shots or when white fuzz begins to appear. If the
crossbow has been exposed to excessive moisture you may need
to apply wax sooner.

PRIOR TO EVERY SHOOTING SESSION, IT IS
RECOMMENDED THAT A COMPLETE CHECK OF CABLES,
WHEELS, SCREWS AND ARROWS BE MADE.

• Always store your crossbow in a safe, dry place.

• Do not expose your crossbow to extreme heat, such

as closed, hot vehicles or near heat sources.

• Inspect cables and strings for signs of wear. Cables
showing wear should be replaced immediately by
an authorized service center or the factory.

• Periodically put a few drops of quality lightweight
machine oil in the trigger mechanism.

• Periodically lubricate the eccentric wheel axels with
lightweight machine oil.

• Keep the flight track and the string serving waxed,
reducing friction.

• Your prod can be left strung indefinitely although
we do not recommend that the bow be left in the
cocked position for periods longer than four hours.

With reasonable care of your equipment and diligent practice,
your crossbow will remain an accurate, highly efficient hunting
weapon.
