The Barrett M107A1 is a semi-auto .50 BMG rifle from Barrett Firearms (brand part no. 20184), built on the same battle-proven platform that has served U.S. and allied military units around the world. This configuration pairs a 29-inch fluted barrel with a full-length Picatinny rail receiver and M-LOK handguard, giving shooters a stable, accessory-ready foundation for optics, bipods and other mission-specific gear. A quick-detach bipod mounts directly to the forend for a steady prone or supported shooting position, while a modular rear grip on the receiver’s M1913 rail accepts an optional monopod for added stability at the shoulder. Built for long-range precision work, this M107A1 is equally at home on a static range or supporting a designated marksman in the field.
