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")

 

Bravo Company MFG, Inc. US Patent 8904691

    MCMR 13

    I installed the MCMR on a 13.7 barrel with a Deadair keymo adapter, in order to have a tight gap to the silencer I milled .2”off the sides which gives a nice .125” gap between the HG and silencer. It is nearly the exact same diameter as the Deadair sandman S and it looks good,
    I would buy again and recommend even if modifications are needed it’s a very solid platform.

    MCMR 13

    I have used the keymod version of this rail in the past, and the M-LOK version is just further proof that these rails are truly among the very best the industry has to offer. Certainly on par with Knight's, Geissele, etc. I'll be using this with a 13.9" Criterion Core barrel (still waiting) and a Sandman K (NFA jail).

    Too Long for 13.7 Inch Barrels with Suppressors

    This is a great rail. I've ordered 3 or 4 of these in the past and they have all worked great. I purchased this 13 inch MCMR to put on a 13.7 inch build. The MCMR is just a hair too long when trying to attach a Surefire suppressor. Removing some material will be required. Otherwise, I suggest purchasing a shorter version. Overall, would buy again.

    Mcmr handrail

    I bought an m c m in the past from Bravo Company and have it on one of my AR-15 which fits like a glove to my Bravo Company upper receiver assembly. I have yet to attach the new ones I purchased since I cannot seem to get my hands on another upper receiver assembly until they become available. I'm sure this one will work just as good as the last time I purchased the handrail. As soon as one comes available please let me know ASAP thank you very much I will definitely purchase Bravo Company again in the future.

    Best rail on the market.

    I have the 13” and they are great. I wish you made a 15” that would fit a M&P 10.
