BCM® MCMR-7 (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 4.8 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 7.39"

Designed to be used with a carbine length, mid length, or rifle length gas system with a FSB or a pistol length gas system with a low profile gas block.

 

 

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

    MCMR-7 Great Handguard

    Posted by Denny on Sep 1st 2020

    This is the second BCM handguard I have purchased. I put this one on a 300blk custom build. These are very sturdy but very lightweight at the same time. Quality is top notch. You get what you pay for and this is no exception. I highly recommend these handguards for anyone looking for a top of the line rail for a mid level price. Shipping was super fast too.

    I am very pleased with this hand guard. It is built incredibly well and boy is it light! For having a “bulletproof” reputation, I was surprised at the weight. It fit tight like it should and I couldn’t be happier with the rail. For my first time buying something BCM, I am very happy and will be buying more in the future!

    Awesome Handguard

    Posted by Brandon on Jul 9th 2020

    I love this handguard! It lines up perfect with the rail on my upper receiver and fits nice and snug (it's not going anywhere!). I love how lightweight it is too. And, it just looks beautiful. Oh, and I also love the QD swivel attachment that comes with it.It is super solid.

    My first AR build was almost all BCM parts and it went together beautifully and has always functioned great.

    For my most recent build in 9mm, I got one of the cheapest upper parts kits I could find because I wanted to save money. Well, you get what you pay for and the charging handle broke during function testing. The upper receiver had out-of-spec holes so I couldn't install the dust port cover or forward assist and then when I finally went to put on my front sight, I found that the morons who built the handguard had made the pic rail profile too tall so my sights wouldn't fit. I immediately got on BCM to order this to replace it (I also bought a BCM charging handle to replace the broken one). I had every confidence in their quality and they didn't disappoint. It went on great, looks fantastic, and lines up perfectly (oh, and my front sight is now sitting proudly up on the rail. I wish I had just started with BCM to begin with.

    BCM MCMR-7 M-LOK
    New rail came VERY promptly. Installation was not overly difficult for one of Neanderthal mechanical skills and the unit works great.
