BCM® MCMR-10 (M-LOK® Compatible* Modular Rail) Handguard
Flat Dark Earth Cerakote (LIMITED QTYS)

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")

    Durable. Fit and finish is top notch. The included pic rail section and qd mount were really nice additions. Not sure you could pick a better handguard for the money.

    Quality stuff.

    This is good ole BCM quality! Install went smooth, some light heat on the rail and a few light taps with a rubber mallet and it was good to go. Solid as a rock! One cool thing is that with a carbine length gas system the two Allen screws on the bottom of the low pro gas block are perfectly accessible from the bottom through one of the m-lok slots. I ordered this to go along with some cerakoted aero precision recievers, the colors are very similar but not an exact match, which worked great for me.
