Bravo Company MFG,
Inc. Introduces a New Series of Upper Receiver Groups, featuring the NEW Daniel
Defense Lite Rail III™(DDM4)
The AR15 Lite Rail III 15.0 is an extended free float rail
system designed to be used in conjunction with a low profile gas block on a
carbine, mid-length, or rifle-length gas systems. This rail system
gives the end user even more “real estate” to mount various accessories
available to the AR15 platform. When mounting a front sight to the top rail, it
allows the shooter to have an extended sight radius enabling more precise shot

Weaponry, by BCM®
Made by Bravo Company MFG, Inc. (BCM®) These Barreled Upper
Receiver Groups are designed for shooting professionals with the Mil-Spec
features for the demands of their duty. They are fully assembled, headspaced,
and test fired. These do not include bolt carrier groups, UNLESS
selected from the drop down menu above.
As a note: BCM® barrel components are parkerized separately
before assembly. Prior to shipping, all BCM® upper receiver groups are test
fired for function, laser bore sighted with a Milspec carry handle for sight
alignment within Mil-Specs, and then batch samples are test fired for accuracy.
As such, the upper receiver group will show handling marks consistent with
these quality control procedures.
M4 Feed Ramp Barrel Extension
M4 Feed Ramp Flat Top Receiver
In developing the USGI M4 carbine as one of the primary
weapons for today’s infantry, some modifications were performed to the original
M16 platform to enhance the reliability of the shorter barreled carbines. With
the shorter carbine gas system and the increased gas port pressure, the carbine
cycled faster, and at times the cycle rate could be faster than the magazine
would feed ammunition. One of the modifications done to increase reliable
feeding included enhancing the angle and the length of the feed ramps. This
USGI modification was done to both the barrel extension and the upper receiver,
creating a longer and steeper feed ramp. These Mil-Spec M4 feed ramps are part
of the original CNC manufacturing process. As a result, the factory machined M4
feed ramps on the receiver are hard coat anodized which adds significant
strength to the aluminum. This feature is offered on all BCM uppers and all BCM
T-Marked Upper Receiver
The contemporary M16/M4 rifle is built around the concept
of modularity. All of the BCM flat top uppers feature a USGI type laser etched
T-marks to provide addressing for the remounting of tactical accessories such
as optics, laser sights, etc. This enables the weapon platform to be easily
configured and then accurately reconfigured for each specific mission.
USGI 1/7 Twist Rate
The USGI 1/7 twist rate of all of the BCM barrels is the
preferred twist rate by most professional infantryman. This twist rate has
proven very versatile and can effectively run the new heavier 5.56 ammo that is
hugely popular with military and private security personal for its’ superior
Mil-Spec Barrel Steel (Certified
BCM barrel steel is Mil-Spec per MIL-B-11595E, and is
independently certified. This grade (CMV) of steel is a Mil-Spec steel used in
the USGI M16 family of rifles; it is stronger and will last longer than the
typical barrels offered in the commercial market. This Mil-Spec grade steel
gets its’ additional strength and rigidity from an increase in carbon and/or
vanadium in the alloy. This will offer increased barrel life and performance
through use in all types of extreme environments and temperatures.
Chrome Bore and Chamber
One of the first modifications that were made to the
original M16 in the mid 1960’s was the addition of the chrome lined bore and
chamber. It is now a world wide standard in the industry for a battle rifle.
The chrome bore and chamber is harder than the barrel steel and on the USGI
M16/M4 rifles will aid in chambering, extraction, and reliability. It increases
velocity, and also resist against fouling and corrosion from extended use in
the field. This gives the end user a longer barrel life with less required time
in maintenance and cleaning.
Manganese Phosphate Barrel Finish
Barrels are parkerized with the manganese phosphate finish
(Mil-Spec A-A-59267). Military specifications also state that the entire barrel
surface is phosphate finished to create a porous surface to absorb oil as to
resist against corrosion from the elements. BCM barrels are phosphated before
installation of front sights. This is a much more extensive assembly operation,
but insures that the entire barrel is finished and protected, even under the
front sight base.
5.56 NATO Chambers
The USGI 5.56 NATO chamber is the best choice for effective
deployment, reliability, and compatibility, of higher chamber pressures of
Government Barrel Profiles
Duty rifles are built to be carried - day in and day out.
The USGI barrel profiles (often referred to as the Government Profile) enable
the operator to carry their weapon for longer periods of time and deploy them
faster than the heavier commercial H-Barrel counterparts. The government
profile barrel is also compatible with the current M203 mounting systems.
HPT / MP Inspected Barrels
Military specifications require that barrels undergo a HPT
(High-Pressure Test) load as a part of quality assurance procedures. Commonly
referred to as a proof load, the M197 HPT is rated for 70,000 psi. BCM barrels
are proof loaded and then MPI (Magnetic Particle Inspected) to detect any
possible flaws in the barrels surface. The barrels are MP inspected with both
circular and longitudinal magnetic fields per ASTME1444-01 (current Mil-Spec)
to assure a high quality finished product. All BCM barrels are marked HP MP as
our proof load marking.
