Professional Grade Weaponry, 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.

    Just what I was looking for !

    Posted by J. R. on Oct 27th 2017

    Only place where I could find a duty grade mid weight barrel with some fluting. Totally happy with the product. Feed ramps, gas port, and threading were all perfect. Nobody likes to spend money, but the price wasn't terrible.

    Good stuff

    Posted by Arnold Rogers on Oct 27th 2017

    Been to the range twice and 2 patrol rifle classes, and the results are good. About 1 mag of slow shooting to break it in and remove any burs. Total weight with light, MRO, sling, and full mag is a pinch over 7lbs. Barrel is plalenty accurate and light weight. Gonna get the 300 blackout next.

    The quality of this barrel is second to none, as well as the fast shipping. I received my product within 3 days of ordering it. I am very pleased with this company and will be ordering an 11.5" version of this barrel for another build. Thank you guys for everything you do!

    Exactly what I was looking for

    Posted by Rich R on Sep 22nd 2016

    Love this barrel. Purchased this for my first complete build and love the way it performs and balances.
    Have always been interested in trying a lightweight barrel but was reluctant only because I plan to keeping it forever and wanted the best I could afford. Pencil profiles just look strange to me. Once I saw this I knew I needed it. It's heavy were it needs to be and slim towards the muzzle. It just made sense.
    I've had it for over a year and a few thousand rounds on a Wilson Combat matched receiver set. Just recently swapped it onto a spare BCM upper and knew I had to get a BCM lower and a kmr. Now it's perfect. Balances great and is a joy to shoot and show off to friends. It feels light and swings easily. Even with an old surefire e series light out front I don't feel any weight past the mag well.
    Try it. You'll like it. I may just get another
    Thanks BCM!

    Shaking with excitement!

    Posted by Seth Miracle on Dec 4th 2015

    This build was meant to be lightweight...coming from a heavier profile 16 inch barrel this feels like there isn't any weight past the mag well! The chrome lining is high quality no chipping anywhere I could see! So excited to make pew pew with this barrel!
