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

The KeyModT 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 KeyModT 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 KeyModT instead of picatinny, allowing for a lighter, cleaner, and less bulky weapon system.

Includes BCM® KeyModT Sling Mount.

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 KeyModT Fasteners on Polymer accessories. Aluminum Picatinny rail sections may be torqued to 30 in/lbs.
