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")

5 of 5 Perfect Product August 20, 2019
Reviewer: Joshua R.  
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.

5 of 5 Solid June 4, 2019
Reviewer: Ty from WI  
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.

4 of 5 Great for AR Pistol Build June 4, 2019
Reviewer: M. Oakes from Austin, TX United States  
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.
