LMT Defense MARS-L MRP Monolithic Rail Platform 5.56 NATO Black Rifle

Description

Product Overview

The LMT Defense MARS-L MRP is a 5.56 NATO semi-automatic rifle built around LMT’s patented Monolithic Rail Platform. Its upper receiver is machined from a single aerospace aluminum forging and provides an uninterrupted 1913 Picatinny top rail with M-LOK attachment points on the remaining sides. The 16-inch chrome-lined chromoly barrel uses a 1:7 right-hand twist and a direct-impingement operating system. A removable barrel design allows fast caliber and barrel configuration changes while maintaining return to zero with the same barrel. The ambidextrous MARS-L lower receiver includes bilateral controls, a two-stage trigger, an ergonomic textured grip, and an adjustable SOPMOD stock.
