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
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
