Life Saving Tools, by BCM®
These are stripped 11.5" carbine gas Standard 11595E barrels with gas ports installed and dimpled for a strong gas block installation.
M4 Feed Ramp Barrel Extension
In developing the USGI M4 carbine as one of the primary weapons for todays 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 barrels.
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 ballistics.
Mil-Spec Barrel Steel (Mil-B-11595E)
BCM barrel steel is Mil-Spec per MIL-B-11595E. 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. The 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 1960s was the addition of the chrome lined bore and chamber. It is now a worldwide 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 military ammo.
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.

    Love it!

    Exactly what you are looking for if you are reading this. In my experience 11.5 is superior than 10.5 for a variety of reasons, but to each their own. I highly recommend this. Won't comment on accuracy due to a multitude of factors like shooter, ammo, trigger etc... but for myself I couldn't be more pleased especially at 300 yards.

    Solid Quality-Second to None

    I chose BCM because of their reputation for having the best components. I could have gone cheaper with different brands but I was building my truck gun and I had to trust my life with these parts. I chose BCM for the barrel, gas block and tube, and the most important part, the bolt carrier group. I am completely happy with my build and have had no issues. Thanks BCM!

    11.5" BCM Barrel

    Used for sbr. Shoots great with crappy M855 at 100 np. Groups easily less than 2" with no rest shooting free handed in the prone.

    Awesome tube

    The this barrel on my SBR project and went right to the range with it. Put about 7 mags through it and it ate everything I put in it. No problem running through steel (tula, wolf, brown bear) or brass. Haven't shot groups with it yet but I can already tell itll out shoot me, off hand any day. Overall I'm extremely impressed so far, with only 200+ rounds through it, it still has a lot to prove but doubt ill be disappointed. Really glad I spent the extra couple bucks for a BCM!

    BCM is Great

    Quality barrel delivered fast from a great company. Pre-drilled gas block dimple was a plus.

    A solid barrel

    Ordered this to replace my 14.5 BFH. I wanted something shorter and this totally fit the ticket. The product i recieved is totally qualified to wear the BCM name. Perfect shape and shipped in less than 24 hrs. Thanks a lot BCM!!

    BCM is BEST

    The fit and finish and overall quality of this barrel is right on par with the rest of the excellent products I've come to known BCM for producing.

    Another thing to I have to commend them for is their incredible customer service. Their after hours automated customer service email system is unreal. This followed by a prompt response and action to correct a mistake I made in the order, with no hassle... I only wish other companies would implement the same kind of system!

    I am a customer for life.
