Life Saving Tools, by BCM®
These are stripped 14.5" Mid Length 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 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 military ammo.


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.

    couldn't be happier

    Paired this with a blem BCM upper receiver as a little Coronavirus shutdown project. Never worked on fancy fluted barrels in the past, but I knew I wanted something simple without bs twists and designs. Just holding it for the first time I quickly started to appreciate the attention to detail behind it. The thing's a work of art. I'll stick with BCM for my future barrel purchases.

    4th build, first time using this barrel

    I have not shot this rifle yet, but I love the design. The tapered down effect seems like it will transfer heat evenly across the barrel for even wear, with no hot spots. The machining is great, it was packaged very well, and the threads were protected with a rubber cap. The grease used for corrosion protection was adequate and cleaned off with relative ease. The only reason I’m giving 4 stars instead of 5 is because of the fluting. There is nothing wrong with it, but it is for function only. I usually don’t care for how my weapons look, I don’t build them to look cool, I build them to work, but I feel like the fluting could have looked a little bit better. It just seemed rushed.

    Badass barrel!

    This is a piece of art. Put 500 rounds through it the first day I had it without a hiccup.

    This is an amazing barrel. I just wish they made an 18" medium weight fluted barrel because the 18 in barrel they make is just to heavy. Good job BCM. (Seriously make an 18 inch version of this barrel)

    Excellent choice!

    If you're planning on running a suppressor, this is the barrel to go with. It evens out the who rifle and you won't be disappointed.

    I won't talk about groupings because there are to many other factors like( ammo, trigger, etc...) but I have to say that I've had such a great relationship with this barrel I now have two. The profile is how I believe every barrel should be made. The weight is perfectly distributed so it maneuvers like a lightweight barrel with the accuracy and reliability of a heavy barrel. This is the best barrel I've ever handled , that's why I have two.
