BCM® MCMR-15 (M-LOK® Compatible* Modular Rail)


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 9.2 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 15.0"

Designed to be used with pistol length, carbine length, mid length, or Mil-Spec M16 rifle length gas systems; all with a low profile gas block.

 

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

    Free Float Handguard

    The handguard is a nice design. Very well put together. The rail is very lightweighted and it come with all the tool you need to assemble your handguard. The only issue I have is the finish is like a Non-Polish finish which make it easier to scratch up. It will be nice if they can add a more polish finish feel like Daniel Defense Rails. Overall a very nice design with BCM writing on the side.

    Installed on a 20” upper. Amazing quality

    Previously, I was running a fixed front sight/gas block on a 20” upper. I decided I wanted more accuracy out of the barrel and more mounting options so a friend recommended BCM. They shipped the rail quickly, and it included everything you would require to install the rail (minus a vice, lol.) the rail is lightweight, incredibly sturdy, with generous amounts of MLOK fittings, and great craftsmanship throughout. The BCM logo isn’t massive or obnoxious, and everything fit perfectly on an Aero upper. They even threw in some extra goodies like stickers and an MLOK picatinny rail. I will definitely shop BCM again for the next build.

    BCM MCMR

    The BCM MCMR is exactly what I was looking for and everything I’ve gotten from BCM has been great. The rail is clean and looks great with no unnecessary things about it. I will definitely buy more of these rails for now on.

    15” mcmr

    As per usual, BCM has shown me why they’re one of the go-to companies when it comes to quality. Tossed a full length mcmr on my rifle build and am kicking myself for not doing it sooner.

    Great handrail

    Been using the magpul MOE 7 inch handrail for years finally went free floating and I am happy that I did despite the changing of the A2 front sight this new handrail is sturdy feels like what ever I add to the hand rail will hold zero will find that out once I get to shoot it. I have no doubt that it will do just fine.
