LMT Defense MARS-H DMR 20in Semi-Auto Rifle

Description

Product Overview

The LMT Defense MARS-H DMR is a semi-auto 7.62x51 NATO precision-oriented rifle built on LMT’s monolithic rail platform (MWS). It pairs an ambidextrous MARS-H lower with an upper receiver that uses the MRP-style monolithic rail for rigid alignment and practical side-loading barrel removal, while maintaining return-to-zero performance with compatible barrels. The 20 in stainless steel barrel, 1:11.25" twist, and straight gas tube direct-impingement system are designed for dependable service and long-term durability.
