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")

    Gets hot real quick

    First time i ever took it out shooting it got really hot and it was unbearable to shoot, got some rail covers to help with the heat to make it at least bearable, I would recommend to either use gloves or get some rail covers with these rails, other than that the rails are nice and light with an easy installation of the rails and attachments to the rails, was also nice that they included a little 2 inch MLOK rail

    BCM for the win

    got this to pair with my 13.7" barrel. The two side protrusions go about half way up the threads on it, so be aware of that if you plan on running a suppressor with a QD. Other than that, its solid, as expected from BCM!!

    Perfection

    I have built 12 of my AR’s with these BCM rails. They are phenomenal. I have never had any issues. These rails are a perfect fit in the hands and I have never had an issue retaining zero with my peq-15 rail mounted

    bcm mcmr 13 inch handguard

    Fantastic handguard. Spec is super tight and fit super well. Construction is great and super light overall. Took it out immediately after finishing the build and is honestly one of the best handguards I've ever used. Probably going to use BCM guards from now on

    MCMR Handguard

    I have (3) of these MCMR handguards, one being on my back up duty rifle and others for personal home defense.
    Best handguards in business, have a lot of rounds down range with them and they have held up to the abuse despite being very lightweight I was very surprised. Anything BCM made is of extreme high quality, and something I trust my life with on or off duty. THANK YOU!

    Perfect handguard system

    This is the best handguard that I have used to date. The mounting system is great and the install instructions are easy to follow. Does require a torque wrench and some specialty tooling to hold your upper, but it’s super easy to install either way. Handguard attachment is much better than the Midwest rail that this is replacing. I never did like how that rail mounted, but this one seems solid as a rock. Would recommend to anyone.
