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")

    Carbine length hand guard

    BCM is always top notch kit. This hand guard totally transformed my pistol length upper into pure magic.. The previous picatinny rail that was on there was bulky and combersome. BCM hand guard transformed it into a sleek, lighter with more eye candy appeal blaster upper. I’m totally happy and would recommend. 100% guarantee from a trigger happy range monkey.

    Take your time

    The rail is a great balance between usable rail space and a slim design. Very light weight and robust. I've installed a few of these and the only downside is how well they are made. The tolerances between the rail and barrel nut are very tight. If you are going to install this rail, or any BCM rails, take your time and use the right tools. If you try to install this rail with random tools you have laying in your garage, you're going to have a tough time. Besides the actual process of installing these rails, they are awesome. Well designed and light weight without sacrificing robustness.

    Awesome Handguard

    Very high quality fit and finish. Great inclusion of the wrench and sling QD mount point. Looks great, feels great, is VERY stable. I just wish I could afford the ammo to shoot it as much as it deserves.

    BCM MCMR 10” Rail

    Very happy with this product! I kept reading reviews saying how hard it is to get the rail over the barrel nut but it was quite easy when following the directions. A hair dryer and light taps with a soft mallet is all it took. Install was a breeze and the fit and finish is great! I did add some BCM MLOK covers to help thicken the feel and add some grip.

    Unmatched Quality

    BCM continues to create parts that are top tier in quality, fit and craftsmanship. This was placed on my new 11.5 build and install was smooth.
