Description

The G215 300 Blackout SBR is a purpose-built short-barreled rifle optimized for the 300 Blackout cartridge’s performance envelope. Designed for tactical applications, home defense, and suppressed shooting, this compact platform delivers full powder burn and optimal ballistics from its abbreviated barrel length.

Built on mil-spec forged 7075-T6 aluminum receivers with a Type III hard anodized finish, the G215 SBR provides a durable foundation in a reduced footprint. The rifle maintains standard AR-15 controls and ergonomics while offering enhanced maneuverability in confined spaces.

At the core of the rifle is a 10.5″ 4150 Chrome Moly Vanadium barrel with a Melonite finish for corrosion resistance and extended service life. This barrel length is widely regarded as optimal for 300 Blackout, providing complete powder burn for both supersonic and subsonic loads while maintaining portability. The barrel is chambered in 300 Blackout with a 1:7 or 1:8 twist rate to stabilize heavy subsonic projectiles, and features a pistol-length gas system tuned for reliable cycling with suppressed and unsuppressed fire.

The rifle is equipped with a 9.125″ quad rail handguard in Coyote Tan finish, providing Picatinny rail sections on all four sides for maximum accessory mounting flexibility. This allows for lights, lasers, vertical grips, and other tactical accessories to be positioned precisely for the shooter’s needs. The quad rail design offers a traditional aesthetic with proven durability.

The G215 SBR features standard 5/8″-24 threading for .30 caliber muzzle devices and suppressors, making it suppressor-ready out of the box—a key consideration given the 300 Blackout’s subsonic capabilities.

This is a short-barreled rifle (SBR) regulated under the National Firearms Act (NFA). Purchasers must comply with all federal, state, and local laws, including ATF Form 4 or Form 1 requirements and applicable tax stamps.
