The goal of this lower was to reduce the distance between the receiver and the 100, 150 and 200 round M249/MK46 “NUTSACK” by pulling it up tighter up to the barrel, allowing for a much better prone position (with/without bipod). Made from 7075-T6 heat-treated aluminum with CERRO forging. Slab side cuts make it a thin as possible profile and with a ambidextrous bolt release for perfect use with the MCR® DUAL-FEED™ UPPER M-LOK® COMPACT (MCR-556-DFRMS) or ARES SHRIKE belt-fed uppers.
