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 6.2oz!

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 10.5"


Mounting hardware, 2.4oz, for a total of 8.6oz on a 10 rail.

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

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

    Top notch quality

    The BCM KMR rail is super light and has top notch quality. There's a reason why my patrol teammates and friends who are deployed use BCM and trust the gear with their lives. Already had an sbr upper and this handguard just made it that much better. My next sbr upper will be all BCM. Keep up the good work guys!!

    So nice!

    Purchased this for my first pistol build and immediately got back on the site and ordered the 13 in one for my rifle. Extremely light, strong and the thinner profile is really nice.

    Literally this handgaurd had a very tight tolerance when I went to put it on my AR. I've been buying Bravo Company products for a while now and I love everything they have to offer.
