LMT MARS-L PDW | Complete Lower

The LMT MARS-L PDW Complete Lower Receiver is an AR-15 compatible lower receiver assembly featuring the Modular Ambidextrous Rifle System (MARS) design. The receiver incorporates fully ambidextrous controls, including the selector, magazine release, bolt catch, and bolt release, allowing operation from either side of the firearm. An enhanced flared magazine well and integrated ambidextrous mechanisms are machined directly into the receiver to support efficient magazine changes and handling.

This complete lower assembly includes several factory-installed components commonly used on AR-15 platforms, including an LMT two-stage trigger group, winter trigger guard, ergonomic pistol grip, and QD sling endplate. The lower is equipped with a PDW-style buttstock, designed to provide a more compact overall length compared to standard AR-15 stocks. The MARS-L lower receiver is compatible with AR-15 pattern upper receivers chambered in 5.56 NATO / .223 Remington or .300 AAC Blackout.
