BCM® MCMR-10 (M-LOK® Compatible* Modular Rail) Handguard


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.
  • Proprietary engineered profile offers additional cross sectional strength.
  • Steel Barrel Nut (same KMR, MCMR, and QRF series), to resist movement under heat.
  • Hard Coat Anodized per Mil-A-8625F, Type III, Class 2
  • Handguard alone weighs 6.6 oz
  • Handguard mounting hardware 2.3 oz
  • Includes BCM M-LOK Compatible Sling Mount, (FREE for a limited time)
  • 1.3" Inside Diameter
  • 1.5" Wide


Actual length when measured to flare is 10.5"

Designed to be used with pistol length, carbine length, or mid length gas systems; all with a low profile gas block.

 

The barrel nut will fit over all mil-spec diameter barrels (max of 1")

    MCMR10

    I really like the rail size and design. I do need to say though that it is extremely tight on the barrel nut. So much so that even with a heat gun it was no easy task to assemble. Also read the directions, if you put the rail too far back you cannot align the locking bolts and will damage them as well as the rail. I learned this the hard way.

    10” rail

    Been using BCM charging handles and mod zero grips on all my builds. Now I will also be using their rails. Everything l have used from this company has been better than anything else I have tried. Thanks BCM

    MCMR 10” rail

    Live this rail!! Replaced a LaRue 9” quad rail with this on an 11.5” rifle. Not only does it save weight, it looks and feels so much better. Installation was easy enough, fit is perfect, rock solid rail!!

    Awesome handguard

    It fits tight and feels great in the hand. Absolutely no complaints, especially for this price. I definitely recommend!

    Perfect Product

    Originally had an upper put together and didn't really understand what I needed for rail length. Thankfully BCM offers a lot of their hand guards in various lengths. The one I purchase was the 10" length for the barrel that I have is a Ballistic Advantage 11.3". It's a close fit, but it still has clearance for me to swap out muzzle devices if need be. Communication, notification, and shipping services were superb.

    Solid

    Great product. Light, slim, strong. Tight fit makes it a bit of work to get on, but once on it locks in rock solid. Bravo makes good shit and they ship fast.

    Great for AR Pistol Build

    I did a recent pistol build with a Aero Precision upper/lower, a Ballistic Advantage 11.5” barrel and all the other high end trigger, pins, etc...so, I wanted the best handguard I could find.
    Well, it turned out great in the end, but there were a few obstacles during the build. First was that one of the two screws that’s included was damaged (BCM took care of with no questions asked...great customer service!) The second was the fit over the barrel nut, which was incredibly tight. The project was finished and looks great, but getting the handguard off will be next to impossible...if ever needed.
    The MLOK rail, length, overall build quality and customer service are outstanding and will bring me back. Just wish it wasn’t so tight that it needed to be assembled with a rubber mallet...literally.
