LMT Defense MARS-H DMR 7.62 X 51 20″ Barrel 20-Rounds

LMT Defense MARS-H DMR Features

The LMT Monolithic Rail Platform (MRP™) is the only true monolithic rail platform, precision-milled from a single solid piece of aerospace aluminum forging. This design allows for unparalleled durability and modularity, utilizing two side-accessible locking bolts to secure the barrel extension for a full 360-degree engagement, ensuring a fast, tool-free barrel swap while maintaining return-to-zero performance.

The MLKMWS upper receiver offers 19.25 inches of uninterrupted Picatinny rail at the 12 o’clock position, while the remaining seven sides provide M-LOK compatible attachment points, maximizing customization options for optics, bipods, lasers, and accessories. The low-profile gas block and straight gas tube contribute to reliable operation, enhanced durability, and consistent performance.

The MARS-H ambidextrous lower receiver features a precision EDM-machined two-stage trigger, an enhanced winter trigger guard, and a QD swivel endplate for sling attachment. It incorporates fully ambidextrous controls, including a bolt catch and release, magazine catch, and safety selector, making it ideal for both right- and left-handed shooters. The SOPMOD stock and LMT ergonomic textured grip ensure a comfortable and stable shooting experience.
