The PMR30 operates on a hybrid blow back/locked-breech system, allowing for the use of a wide variety of ammunition as it adjusts depending on the pressure of the cartridge. It uses a flush fit, double stack Zytel nylon magazine with round count ports. The trigger is a crisp single action with an over travel stop. It has a thumb-activated ambidextrous safety lever. The slide locks back after the last shot and a manual slide lock lever is also provided. Features dual opposing extractors for reliability; heel magazine release to aid in magazine retention; Picatinny accessory rail under the barrel, urethane recoil buffer and captive coaxial recoil springs. The PMR30 disassembles for cleaning by removal of a single pin.
