BCM® MCMR-13 (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 8.2 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 13.4"

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")

Please note: Nylon/Polymer Picatinny rail sections are for NON-load bearing accessories only (grips, hand stops, light mounts). For load bearing accessories (bipod mounts, sling mounts, vertical grips, barricade supports), we recommend aluminum Picatinny rail sections. Do NOT exceed 20 in/lbs. when securing fasteners on Polymer accessories. Aluminum Picatinny rail sections may be torqued to 30 in/lbs.

    Awesome rail

    5 star rail. Have handled other aluminum rails in my day which have sharp edges or weird finishes that don't feel good on the hand... This rail is superb! Very secure attachment (you have to heat the rail to slip it over the barrel nut, read the directions!) Great finish that feels good in the hand, edges are deburred so you don't feel like you're going to cut yourself on it.. looking to get another one for my ar 15 pistol

    Very good quality

    I haven't installed this yet thus missing one star. I didn't feel it was fair to right highest without having tested this. It is made very durably and of excellent quality. I have no doubt it perform past expectation.

    Great handguard, excellent method of attachment

    My favorite part about the mcmr is how it attaches to the barrel nut, very stable and not able to walk out over time or under recoil
