BCM KMR-13
Bravo Company’s KeyMod™ Rail, 13”
Manufactured from an exclusive blended aluminum and
magnesium alloy, it weighs 30-40% less than aluminum with the same strength
properties. 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 5.5oz!
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 13.4"
Mounting hardware, 2.2oz, for a total of 7.7oz on a very
long 13” rail.
The KMR’s propriety finish was originally developed for the
Aerospace industry. It is a plasma
deposition process which creates a stabilized ceramic-like surface coating with
superior wear resistance when compared to anodize or even hard chrome. The stabilized nature of the coating means it
has a higher corrosion resistance as well, due to the lack of ‘pores’ in the
surface.
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 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.
“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”
