Description

The LMT Defense MLKMWS 20" 6.5 Creedmoor MARS Semi-Auto Rifle System (MLK6520LA-MARS) is LMT's premier long-range precision semi-automatic battle rifle, combining the exceptional ballistics of the 6.5 Creedmoor cartridge with LMT's combat-proven MARS-H ambidextrous lower and the new ARCA-integrated 15.3" M-LOK upper receiver chassis. New for 2026, the MARS-H DMR series now features an integrated ARCA rail at the rear of the handguard for seamless tripod and bipod mounting without additional accessories. Utilizing LMT's patented Monolithic Rail Platform — the only true monolithic rail platform milled from a single solid piece of aerospace aluminum forging — this rifle delivers exceptional accuracy, full-360-degree barrel engagement for superior heat dissipation, and rapid barrel-change capability with return to zero.
