The freefloating Bravo Company MCMR M-LOK Rail eliminates external load on the barrel, reducing deflection for more accurate shooting. Featuring the same industry leading barrel nut and lock up design introduced on BCM's KMR handguard, the MCMR series of handguards delivers modularity for the M-LOK platform. Its proprietary patented mounting system (US Patent 8904691), includes a mechanical index to the 12-o’clock rail and positions mounting hardware to mitigate movement caused by heat.

Another Win for BCM!


When BCM released this handguard I jumped on it. Having a 15" KMR on another build I couldn't wait to add another one in Mlok. I can't say enough great things about it! It is super light, nice and narrow, and feels great in hand. I liked it so much that I ordered another one (shorter) for a 14'er build I'm working on. I have a few favorites and the MCMR/KMR is an example of that!

Great BCM Rail!

What a great rail! I used this as an upgrade to my existing polymer one that came with my rifle. It is surprisingly lightweight and slimmer then my original one. I was torn between this one and one from another manufacturer and ended up going with this one due to the diameter being smaller then the other. Very happy with this and it looks awesome on my rifle!

My go to hand guard/rail

KMR was my go to hand guard rail on my better builds until BCM introduced the MCMR. My ARs don’t leave home without them. Solid, lightweight, well made and well priced. Have used many, but this is the one.

It’s legit
