produces the highest quality AR15/M16 type rifles
and carbines manufactured in the world today. We are
a U.S. Government Defense Contractor - selling to
U.S. Military Forces and Governmental departments
- as well as many foreign governments and armed forces.
In order for us to fulfill U.S. Government contracts,
we must manufacture our products to strictest U.S.
Military Specifications. What this means to the Law
Enforcement Department, or Individual Officer, is
that you can purchase the same mil. spec. quality
product that we would deliver to the U.S. Government.
We will only manufacture one grade of weapon - of
the highest quality possible. We do not, and will
not, "cut corners" on a product that may
make a life or death difference to you - your partner
- or your department.

We machine our Barrels from either the best grade
Chrome-Moly Vanadium Steel, or 416 Match Grade Stainless
Steel. Our heavy profile Barrels (standard on most
models) step down from 1" diam. at barrel nut
to .750" at the sight base to improve heat dissipation
and decrease barrel whip. The majority of our barrels
are button rifled - right hand twist - 1 turn in 9",
as we've found that the 1 in 9" twist gives optimum
accuracy results with a broad range of ammunition,
and will stabilize bullets up to 75 grains. DCM Competition
Rifles are 1 in 8" twist for the very heavy bullets
used in high power competition.
Chrome Lined Bore & Chamber:
A chromed bore and chamber - as in most of our Chrome
Moly Steel Barrels - can double the barrel's life
if proper care and regular maintenance procedures
are observed. The chrome protects against corrosion,
and as it is harder than the barrel steel, it reduces
friction, increases velocity, and aids in chambering
and ejection. Chrome lined barrels also clean up easier
because lead, copper and powder fouling simply does
not adhere as easily to the chrome lining - so you'll
spend less time cleaning after a day at the range.
Note: With any chrome lined barrel, you should avoid
leaving ammonia based solvents, bore cleaners, or
pastes in long term contact with the chrome lining
(i.e. over-night soakings) as the ammonia can react
with the chrome to cause oxidation. Regular session
cleaning will ensure proper barrel care and long life.
We apply a Manganese Phosphate finish to our barrels,
and other critical steel parts, to protect against
corrosion and rust and to produce a matte black, non-reflective
surface color. We do not paint any of our parts. Finally,
Bushmaster rifles and carbines are laser boresighted
at the factory to assure that the accuracy inherent
in our barrels works in coordination with the sights
that we put on them.
Manganese Phosphate Finish: We utilize
the mil. spec. recommended protective finish for steel
in our manufacturing. This finish protects against
corrosion and rust, and produces the correct matte
grey/black military surface color. We do not paint
any of our parts.
Forged Front Sights: The front sight
base is not a casting. Bushmaster uses only steel
forgings which are far superior in tensile strength.
Your weapon won't be disabled if you bang it against
Receiver Features: We machine our
receivers to fit together with two standard mil. spec.
push pins. This offers simple “tool-less”
take down in the field - no need for two screwdrivers
as with some other brands. We incorporate a brass
deflector into the aluminum upper receiver forgings
for ejected shell control and a raised “fence”
area around the magazine catch button prevents accidental
release of the magazine - all per latest military
Rear Sights: We use the standard
mil. spec. A2 Dual Aperture Rear Sight which incorporates
adjusting knobs for both windage and elevation. Our
A2 sights feature 1/2" incremental windage adjustment
at 100 yards instead of the older version which offered
only 1" increments - additionally, the adjustment
knobs on the new A2 rear sight eliminate the need
for a sight tool. The beauty of the dual aperture
flip-up is that the same sight can offer both quick
target acquisition (with the field aperture) and fine
distance sight picture (with the target aperture).
Stock and Grip: We install the latest
A2 standard trapdoor buttstock - which is 5/8"
longer than the original A1 - for a mil. spec. trigger
pull length of 13.5 inches. The black thermoplastic
pistol grip has finger groove and serrated back for
