The 10.5 inch barrel is machined from 4150 CMV steel and threaded 5/8-24 to accept common muzzle devices or suppressors, matching the caliber’s subsonic versatility. The 1:7 or 1:8 twist rate stabilizes a broad range of .300 BLK bullet weights, from lightweight supersonic loads to heavy subsonics.
PSA’s Lightweight Hex free-float rail reduces front-end mass while providing abundant M-LOK slots for accessories. A continuous top Picatinny section integrates smoothly with the forged upper receiver, and the included 45° offset sights give an instant back-up aiming option without obstructing optics.
The forged 7075-T6 lower hosts an SBA3 adjustable brace that locks solidly in multiple positions, enhancing control while preserving compactness. A Hogue-style rubber grip with finger grooves offers a secure, cushioned hold.
Direct-impingement operation, a full-capacity 40-round PMAG, and a hard-coat anodized finish round out a package that balances reliability, capacity, and maneuverability for range, defense, or field use.
