Tuned around Barrett’s proven recoil-operated action, this FDE Cerakote model wears a rugged, low-signature finish over a steel receiver and synthetic furniture, delivering battle-proven reliability and weather resistance. Out front, the heavy-profile 20" barrel optimizes maneuverability while maintaining the terminal authority and downrange consistency .50 caliber shooters demand. A factory bipod, rear monopod, and flip-up iron sights ship in the box—together with a custom Pelican hard case—so you can deploy with confidence the moment it arrives. Why the M107A1 (20") Sets the Standard Serious .50 BMG authority: The shorter 20" barrel balances mobility and muzzle control while preserving the energy and penetration that made the platform famous. Duty-ready finish: Flat Dark Earth Cerakote resists abrasion, chemicals, and hard weather for long-service durability and reduced visual signature. Stability from prone to props: Factory bipod and fine-adjust monopod combine with a long, flat underside for rock-solid recoil management and repeatable shot-to-shot recoveries. Immediate deployment: Ships optic-ready with front and rear flip sights, one 10-rd magazine, and a fitted Pelican case for protected transport to range or field. Confidence under recoil: The synthetic stock, optimized gas/recoil system* and multi-baffle brake (device may vary) help maintain sight picture and shooter endurance over extended strings. *Recoil/operating system details may vary by production run; Barrett’s hallmark is robust, field-serviceable engineering.
