Barrett M107A-S: Lightweight .50 BMG Semi Auto with Enhanced Suppressor Compatibility

For operators, competitive shooters, and collectors who demand a .50 BMG semi-automatic rifle that balances battlefield-proven power with modern ergonomic and suppressor-ready features, this rifle stands out. It pares down unnecessary weight while retaining rugged reliability and accessory options that long-range shooters require.

BARRETT M107A-S is built on the weight-saving improvements introduced with the M107A1 platform while incorporating the S variant’s steel upper receiver for enhanced strength. The rifle is 5 pounds lighter than the original M107 thanks to a lightweight aluminum receiver and other optimized components, and it was engineered from the ground up to be suppressor ready. Key features include a new bolt carrier group and muzzle brake designed to interface seamlessly with Barrett’s QDL series of suppressors, a titanium barrel key, chrome-lined bore for long service life, a full-length Picatinny rail for optics, and a 20-inch barrel chambered in .50 BMG. One 10-round magazine and a bipod are included with the system. Shop this product

Design and Weight Savings

The M107A-S takes the M107A1’s aluminum receiver benefits and balances them with a steel upper receiver on this S variant to boost durability in high-stress components without sacrificing the platform’s overall weight advantages. The approximately 5-pound reduction from the original M107 improves transportability and follow-up shot ergonomics for teams who must move with heavy-caliber rifles.

Suppressor Compatibility and Durability

Suppressor integration is a core intent of the design. A dedicated bolt carrier group and muzzle brake interface directly with the QDL quick-detach suppressor system, letting units mount and dismount suppression quickly while maintaining consistent point of impact. The titanium barrel key reduces weight at a critical junction, and the chrome-lined bore increases barrel life and simplifies maintenance for .50 BMG service rounds.

Operational Fit and Pricing

The 20-inch barrel and included 10-round magazine plus bipod make the BARRETT M107A-S a ready-to-deploy solution for long-range precision and anti-materiel tasks. Chambered in .50 BMG, it delivers the energy and range expected of the caliber for disabling equipment and long-distance engagement. Listed at $11,106.99, this rifle sits in the high-end tactical segment for buyers prioritizing suppressor readiness and proven engineering. View product details and pricing
