The LMT MARS-L 5.56 PDW 10.5" SBR from Lewis Machine & Tool is a short-barreled rifle platform chambered in 5.56×45mm NATO, built around the company’s Monolithic Rail Platform (MRP) upper receiver system. The monolithic upper is machined from a single forging and utilizes a dual locking bolt barrel attachment design that allows for barrel changes within the MRP system. The MLC upper features a full-length Picatinny top rail with additional M-LOK attachment interfaces. The MARS-L ambidextrous lower receiver includes bilateral controls for the bolt catch, bolt release, magazine release, and safety selector. This configuration includes a 10.5-inch chrome-lined 1:7 twist barrel, direct impingement operating system, two-stage trigger, and a compact stock assembly, and ships with a magazine, owner’s manual, and grip panels.
