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 the chamber is harder than the barrel steel and will aid in chambering, extraction, and reliability. It increases velocity and also resists fouling and corrosion from extended use in the field. This gives the end user a longer barrel life with less required time for maintenance and cleaning.

Mil-Spec Barrel Steel (Certified Mil-B-11595E)

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.

Manganese Phosphate Barrel Finish

Barrels are parkerized with the manganese phosphate finish per Mil-Spec. Military specifications also state that the entire barrel surface is phosphate finished to create a porous surface to absorb oil to resist corrosion from the elements. BCM barrels are phosphated before the 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.

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 infantrymen. This twist rate has proven very versatile and can effectively run the new heavier 5.56 ammo that is hugely popular with military, private security personnel, and personal defense for its' superior ballistics.

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.

BCM® has taken great care to ensure the best possible performance and interchangeability. However, due to the large operational range of 300 Blackout ammunition in the market place, BCM® cannot guarantee function will all ammunition types in all conditions.

Optimized for use with suppressors without a adjustable gas block

These barrels were designed to run High Velocity ammo only. Fine tuning may be required in limited instances based on ammo and buffer choices that work best for the desired application. BCM® also recommends running the Crane O-ring (provided with all BCM® Bolt Carrier Groups) over the extractor with 300 Blackout.

BCM® GUNFIGHTER MCMR M-LOK Handguard Kit 5"

Featuring the same industry leading barrel nut and lock up design as originally introduced on BCM's evolutionary KMR handguard, the MCMR Series of handguards gives the shooter modularity in the M-LOK platform.This proprietary patented mounting system (US Patent 8904691), includes a mechanical index to the 12:00 rail and positions mounting hardware to mitigate the movement caused by heat generated by the weapon system.

MCMR features M-LOK Compatible mounting system
Free Float Handguard eliminates loads from barrel, reducing the deflection for more accurate shooting
Precision Machined Aerospace 6061-T6 Aluminum Alloy, for high strength and lightweight
