BCMGUNFIGHTER KMR Handguard
Sorry, this item is out of stock
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 flares forward (towards muzzle end) at the 3 and 9 O'clock positions approximately 1/4"
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.
