The 10.5-inch barrel is machined from 4150 CMV steel and treated with a nitride finish for corrosion resistance and extended life. A 1:8 twist rate stabilizes a wide range of .300 BLK bullet weights, while 5/8-24 threads allow easy attachment of muzzle devices or suppressors.
PSA’s Enhanced Polished Trigger uses a nickel-Teflon coating for a smoother single-stage pull compared with standard mil-spec units, giving the shooter better control without aftermarket work.
The lightweight free-float aluminum handguard spans roughly nine inches and carries M-Lok slots for accessories along with a continuous Picatinny rail that joins the upper receiver, providing over 14 inches of uninterrupted mounting space.
An SBA3 brace offers five-position adjustability, letting the shooter tune length of pull while keeping the pistol compact. The Magpul MOE grip supplies a familiar, ergonomic hold.
Both upper and lower receivers are forged from 7075-T6 aluminum, hard-coat anodized in black, and multi-marked to accept caliber conversions. A pistol-length gas system and direct-impingement action keep the build light and reliable. Made in the USA.
