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.

    BCM Standard 20 "5.56 Stripper Barrel

    Totally 100% pleased with this new barrel. It arrived approximately only three days after ordering,, that's hard to beat. I wanted a 20 inch barrel mainly for deer hunting, I think this would totally work out for the upper I'm building, thanks bravo Company and I will be ordering more from you guys 👍👍

    Best barrel for the money.

    There is nothing to say about these barrels that hasn't already been said. I trust BCM quality control. Last 3 barrels I used were all BCM from different batches (hp/mp stamping slightly different depth and texture of finish) and they all zeroed less than moa at 50 and solid 1-1.5 at 100 when I didn't screw it up. All were 16" free floated using Geissele ssa or ssa-e triggers.

    Great product

    Awesome Leight weight rail , I just can't give it five stars because it did not come with any rail segments or anyway to mount accessories

    Perfect fit!

    I've had nothing but good experiences with BCM and their products. This barrel was a bit of a tight fit in the BCM M4 upper I purchased from a local gun shop but it went on just fine.

    Awesome Quality

    I am only giving it four stars, because I am in the process of building the upper I am attaching this barrel to...so I have not put any rounds down range yet. But I am happy with the over all quality of the barrel, and the quality inspection checks done. I been shopping around for awhile and very few places actually do the different QA testing on it.

    very light

    Lighter then my 16 in midlength. I have not assembled yet but the barrel sleeve fits very snug in the bcm m4 upper. With this barrel and nut, delta ring assembly and triangle, bcm low pro gas block, the a2 flash hider, and the m4 upper it weights 3.134 lbs.

    20" Barrel

    Well, I haven't received the barrel yet but, I always purchase from BMC when I can. Always VERY FAST SHIPPING and I like that.
    I'll be looking for a keymod rail system for that barrel soon

    Great barrel

    I purchased this barrel over a year ago. So far, it's proven to be very accurate in all bullet weights I've tried: 55gr, 62gr, 63gr, 69gr, 75gr, and 77gr.

    I'm still amazed at the low price compared to other barrels on the market. It's perhaps the best bang for your buck barrel out there.
