BCM® KMR Alpha 15


All the advantages and features of Bravo Company s KeyMod™ Rail, now available in 100% aluminum

Manufactured from aluminum, it is lightweight yet durable. Also featuring a proprietary patent pending mounting, indexing and lock up system that mitigates 12:00 rail movement under heat generated from the barrel nut.


Handguard alone weighs 8.6oz!


1.3 Inner Diameter

1.5 OUTSIDE flat to flat.

Handguard flares forward (towards muzzle end) at the 3 and 9 O'clock positions approximately 1/4"

Actual length when measured to flare is 15.0"

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


Mounting hardware, 2.4oz, for a total of 11oz on a very long 15 rail.


The KMR Alpha is hardcoat anodized for corrosion resistance as well as to maintain a non-reflective finish.


The KeyMod interface system was developed by Eric Kincel (now the Director of BCM's product development team) to work in parallel with the current picatinny system. In many applications it will advance modularity past the current 1913 rail system.


The BCM KMR Alpha also allows for a larger range of modularity offering 4 different offset mounting positions between traditional 3,6,9, and 12:00 positions.


In the most basic of applications the KeyMod system allows for universal modularity between various manufacturers of accessories, and accessory rails. A big win for the trigger puller. As the industry advances the modular accessories will mount directly to the KeyMod instead of picatinny, allowing for a lighter, cleaner, and less bulky weapon system.

*Includes BCM KeyMod Sling Mount

Please note: Nylon/Polymer Picatinny rail sections are for NON-load bearing accessories only. For load bearing accessories, we recommend aluminum Picatinny rail sections. Do NOT exceed 20 in/lbs. when securing KeyMod Fasteners on Polymer accessories. Aluminum Picatinny rail sections may be torqued to 30 in/lbs

    AFTER improvements

    Just joking sorta, the construction of the hand guard in my opinion is better than Yankee Hill.
    It’s well built and well cut out. It fit perfect.
    I do however have one complaint. I didn’t like having to beat the crap out of it to get to seat against the upper. I believe in a tight fit, but REALLY!! Especially after I sandblasted and cerakoted it. Hitting it with a rubber hammer at that point on burnt bronze doesn’t look to good.

    Very good!

    This is my third build using the BCM KMR hand guard and it is the best that I have seen. I have used other hand guards on other builds but they are not engenerred as well as the BCM KMR. I highly recommend it.
