The MARS-H brings LMT’s innovative design of their 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 are very intuitive. This “stripped” version comes with the ambidextrous components installed at the factory.
LMT MWS lower receivers are only guaranteed compatible with LMT upper receivers. Other brands may not fit or function correctly.
