Barrett M107A1 .50 BMG 20in Tungsten Gray 10rd

The Barrett M107A1 .50 BMG 20in Tungsten Gray 10rd is a recoil-operated semi-automatic rifle built for long-range precision and specialized applications. This specific configuration pairs a 20-inch fluted, chrome-lined barrel with a Tungsten Gray Cerakote finish on all aluminum components. The rifle is suppressor-optimized from the factory and ships with one 10-round detachable magazine, a bipod, a monopod, and a hard case for transport and storage.

Key Features

• Recoil-Operated Semi-Automatic Action: Why it matters — the M107A1’s short-stroke gas piston system cycles .50 BMG rounds reliably while reducing felt recoil, allowing you to stay on target for rapid follow-up shots without losing your sight picture.
• 20-Inch Fluted, Chrome-Lined Barrel: Why it matters — fluting reduces barrel weight by roughly 1.5 pounds compared to a solid profile, improves heat dissipation during sustained fire, and the chrome lining extends barrel life well past 5,000 rounds of heavy .50 BMG use.
• Tungsten Gray Cerakote Finish: Why it matters — this corrosion-resistant coating on the aluminum receiver and handguard provides a low-glare, durable surface that holds up to harsh field conditions, including salt spray and extreme temperatures.
• Suppressor-Optimized Design: Why it matters — the factory-installed QD muzzle brake accepts Barrett’s own suppressor (sold separately), reducing signature and blast for concealed-position operations or shooting on private land without rattling neighbors.
• Included Bipod, Monopod & Hard Case: Why it matters — you get a stable shooting platform right out of the box with the Harris-style bipod and rear monopod, plus a purpose-built hard case for airline travel or secure storage.

Who It’s For

This rifle is for the long-range shooter who demands .50 BMG terminal energy at distances beyond 1,500 meters. It’s for the competitive ELR shooter who needs a semi-auto platform for fast engagement strings, the military/LE precision marksman who relies on Barrett’s combat-proven reliability, and the serious collector who wants the current-issue U.S. military-spec anti-materiel rifle in a compact, suppressor-ready package. If you’re still running a bolt-action .50 and your stage times are suffering, this M107A1 will cut your split times in half.

Pros & Cons

• Pro: Semi-auto action delivers faster follow-up shots than any bolt-action .50 BMG — you can put three rounds on a steel plate at 1,000 yards in under 4 seconds.
• Pro: Chrome-lined barrel gives you 5,000+ rounds of accurate service life with minimal cleaning, per Barrett’s own endurance testing.
• Con: At 28.2 lbs unloaded, this rifle is heavy — you’ll need a strong bipod and a solid shooting position; it’s not a hunting rifle for hiking miles.
• Con: The 20-inch barrel, while suppressor-friendly, reduces muzzle velocity by roughly 150 fps compared to the standard 29-inch barrel — a trade-off for compactness.
