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")

    Excellent Handguard

    Very good fit and finish. Its very tight. I had to use a mallet to seat it all the way. Im using a Superlative Arms adjustable piston kit. Fits over the gas block perfectly

    No worries here with any of their products. Made to be used hard, not stuffed in the safe. Shipping is also great,, enough said. .

    Haven’t had a chance to install it yet but it seems to be durable despite weighing practically nothing. It would be nice it the barrel but was longer like the geissele barrel nut but the fit is so tight I don’t think it will go anywhere once in place and torqued down.
