THESE SBRs ARE USED, FACTORY, DEPARTMENT TRADE INS. UPPER RECEIVERS ARE MARKED “LEWIS MACHINE & TOOL CO.”

LMT built this short-stroke gas piston SBR with its patented Monolithic Rail Platform, milled from a single high-grade aluminum forging. Two locking bolts on the side of the receiver lock the barrel extension in place. MRP® technology engages the barrel extension for a full 360 degrees and allows the barrel to be removed in seconds while minimizing point of impact shift. One upper can support numerous barrels of varying length, material, and caliber. This particular SBR is equipped with a 12″ chrome-lined piston barrel and a semi-auto bolt carrier group.
