What’s Included
- Falkor Defense Petra .300 Win. Mag. semi-automatic rifle
The Petra is built around Falkor’s FD-30A long-action receiver set, engineered to accommodate .300 Win. Mag. with an extended ejection port tailored for magnum-length cartridges. This configuration places it among the few production semi-automatic AR-pattern rifles in this chambering.
Its 22-inch DRACOS StraightJacket Barrel System is marked US PAT. 8794122 B2 and is paired with a multi-port muzzle brake bearing the Falkor logo. The system is designed for rigidity and thermal management, supporting consistent performance with magnum loads.
The upper carries a full-length 12-o'clock Picatinny rail for mounting, complemented by a long, free-float M-LOK aluminum handguard branded by Falkor and outfitted with added Picatinny rail sections. No sights are installed, allowing the end user to configure the rifle to their needs.
Ergonomics and control meet precision-minded features: an adjustable stock with length-of-pull and cheek rest adjustments (14.0-inch LOP as set) and a rubber buttpad, plus a Magpul MOE polymer pistol grip. The rifle uses a direct impingement operating system with a manual safety, and wears a multi-tone desert camouflage finish across the receivers and furniture.
