The MARS-H brings the innovative design of our MARS-L to the MWS® platform.

The LMT® Modular Ambidextrous Rifle System (MARS®) lower receiver offers ambidextrous controls to include: selector, magazine release and bolt catch and release. The ambidextrous magazine and bolt catch mechanisms are machined directly into the receiver and have been designed to function as ergonomically as possible.

This “stripped” version comes only with the ambidextrous components installed.

LMT® MWS® lower receivers are only guaranteed compatible with our upper receivers. Any other brand may not fit or function correctly.
