Overview

This catalog row represents the exact full-size PSA 5.7 Rock optics-ready threaded pistol, SKU RK01-51655129091. Its factory upper uses a 5.2-inch fluted carbon-steel barrel with 1/2x28 threads and a thread protector, plus an optics-ready 416 stainless-steel slide.

The slide accepts Shield-footprint optics directly. PSA also includes separate RMR and Docter adapter plates, so an RMR-footprint optic mounts through the included RMR plate rather than directly to the Shield cut. Leupold DeltaPoint Pro optics are excluded from the direct cut.

The pistol retains the full-size Rock frame, 23-round magazine family, Glock-pattern sight cuts, and Picatinny accessory rail. It ships with two full-size magazines. Suppressor selection still depends on an exact 5.7x28 rating, the 1/2x28 mount, and the suppressor maker's host instructions.
