Why 300 Blackout?

The 300 Blackout cartridge was purpose-built for the AR-15 platform. It delivers rifle-class power in a compact package, making it ideal for hunting medium game, home defense, and sport shooting. The round's inherent subsonic capability—when paired with appropriate ammunition—offers unique tactical flexibility.

Practical Design

The M-LOK handguard provides genuine modularity. Add a light for home defense, mount a scope for hunting, or keep it simple for range work. The 16-inch barrel strikes a balance between velocity and maneuverability.

This is a rifle built to work, not to impress. It's the kind of gun you'll actually use.
