The barrel is
surrounded by two aluminum lined Fiberglass hand guards which are
notched to permit air to circulate and cool the barrel and also

Helpful Tips in Using this Weapon
- Although the projectile will travel
up to two miles, its' maximum effective range is about 300 meters,
in practiced hands, in daylight, with a stationary, man-sized
target. Most medical personnel won't be able to achieve those
results, so try to hold your fire 'til you "see the whites of their
- Effective rifle fire, other than at
point blank range, requires careful sighting (aligning the front and
rear sights with the target), breath control (try not to breath
while firing), a smooth, steady trigger pull (try to avoid jerking
the trigger), and avoidance of "flinching" in anticipation of the
weapon firing. The latter can be avoided through practicing "dry

Slap, Rack, Bang procedure:

back the "Charging Handle" and release it, ejecting the misfired
round and bringing a fresh round into the firing chamber. Let the
the "Charging Handle" spring back on its' own...don't "ride" it
goes the rifle when you pull the trigger.
- When defending against multiple
targets, try to stop the most threatening target first. Usually that
is the target closest to you. However, someone with an automatic
weapon or shotgun is more dangerous to you and your patients than
someone with a pistol. Likewise, someone with a rifle is more
dangerous than someone with a pistol.
- Take advantage of any cover you may
have. Crouching behind a rock or packing crate is much better than
standing out in the open. If you are caught out in the open, quickly
make a decision to either go to the ground, or to run to cover. If
you go to ground, keep moving (rolling, crawling), to decrease the
chance of your being wounded.
- Should you become wounded, keep
shooting. The best defense against incoming fire is to return fire,
wounded or not.
