PSA 5.7 Rock Complete Pistol, Black

This catalog row represents the exact base black full-size PSA 5.7 Rock, SKU RK01-51655146463. It uses lever-delayed blowback with a straight-recoiling, non-tilting barrel. The barrel and slide start rearward together, then a spring-loaded cam arrests the barrel while the slide continues. This exact base pistol has a 4.7-inch non-threaded barrel and a non-optic slide. It does not inherit the optic cut, 5.2-inch barrel, or 1/2x28 muzzle interface found on separate optics-ready and threaded configurations.

The base pistol ships with one 23-round full-size Rock magazine for 23+1 capacity. Its slide has Glock-pattern front and rear sight cuts, while the dust cover provides a full Picatinny accessory rail for a correctly keyed pistol light.

Owners who want the factory optic and threaded interfaces can replace the upper with the exact complete optics-ready threaded slide assembly. That assembly keeps the slide, 5.2-inch 1/2x28 barrel, recoil system, optic cut, and included plates together as one matched upgrade rather than treating the barrel or plate as a generic cross-fit part.
