LMT Defense MARS-H Battle Rifle Features
The MARS-H Battle Rifle is built around LMT’s Monolithic Rail Platform (MWS®), providing a rigid, free-floated barrel system that enhances accuracy and modularity. The MLOK handguard allows for easy attachment of accessories, while the monolithic upper receiver ensures a solid, one-piece design for increased strength and durability. The 13.5-inch chromoly steel barrel is engineered for optimal performance with a 1:10″ twist rate, providing excellent stabilization for .308/7.62 NATO projectiles.
The MARS-H ambidextrous lower receiver offers enhanced ergonomics and full ambidextrous controls, including the bolt catch and release, magazine release, and safety selector, making it an ideal choice for both right- and left-handed shooters. The two-stage trigger provides a crisp and consistent pull, while the adjustable stock ensures optimal comfort and control. The inclusion of a QD sling attachment point enhances the rifle’s adaptability for tactical use.
