The KeyMod interface system was originally developed by Eric Kincel to work in parallel with the current Picatinny rail handguard system. In many applications, the KMR will offer modularity and customization exceeding the current 1913 rail systems with baked-in rails.
The KMR-13 was manufactured from an exclusive blended aluminum and magnesium alloy, it weighs 30-40% less than pure aluminum with the same strength properties. The BCM KMR also features a proprietary patent pending mounting, indexing and lock up system that mitigates 12:00 rail movement due to heat generated from the barrel nut.
The BCM KMR also allows for a greater range of customization, offering an additional 4 offset mounting points between traditional 3,6,9, and 12:00 positions.
At its heart, the KeyMod system creates the potential for universal modularity between various manufacturers of accessories and accessory rails. As more options become available, new KeyMod accessories will attach directly to the KeyMod slots rather than via Picatinny rail segments, creating a lighter, cleaner, and less bulky weapon system.
