KelTec PR57 5.7x28mm 4.64" 20rd Burnt Bronze Optic Ready Pistol

The KelTec PR57 is a unique take on the 5.7x28mm pistol, using a rotating barrel lockup and a tip-up, top-loading design that fills the magazine through the ejection port with a stripper-clip-style loader. That means no stiff mag spring to fight with and no dedicated loader tool — you press rounds down into a fixed 20-round internal mag. The 4.64" barrel, fiber optic front, adjustable rear, and optic-ready slide cut give you a flat-shooting 5.7 handgun that feeds from the top instead of the bottom.

Recoil on the PR57 is flat thanks to the low-pressure, high-velocity 5.7x28mm round, and the rotating barrel keeps muzzle rise in check. This Burnt Bronze variant wears a Cerakote slide finish over a polymer frame with aggressive grip texturing. The optic cut accepts RMSc / K-series micro dots, and the rail up front takes a compact weapon light for home defense duty. An ambidextrous safety and reversible mag release keep it friendly for southpaws. Comes as a single integrated mag gun — no loose spare magazines, just the internal 20-round stack.
