The PSA 570 Pump is a new 12-gauge, fully modular shotgun built around a receiver with a built-in RMR footprint and compatibility with 870 furniture. Its free-floating hanger system allows the mag tube and barrel to lock up in the receiver, letting users easily reconfigure barrel length and magazine setup at home. The project is nearing completion with production-tooled parts, and a late Q1 to early Q2 release window is expected, with more updates coming before SHOT Show.
