BCM KMR Alpha
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.
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:
7in = 7.39in
8in = 8.39in
9in = 9.4in
10in = 10.5in
13in = 13.4in
15in = 15in
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 BCMs’ 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.
