The PA-15 pistol is built on an AR-15 platform with familiar controls, including the magazine release, bolt catch, forward assist, ejection-port cover, and brass deflector. It uses a direct-impingement, rotating-bolt operating system and feeds from STANAG-pattern magazines. Capacity is 30+1 with compatible magazines.
Its 10.5-inch steel barrel is threaded and capped with an A2-style birdcage flash hider, pairing well with the .300 AAC Blackout chambering for compact handling. The free-float aluminum M-LOK handguard features a continuous, full-length top Picatinny rail for mounting sights and accessories.
Factory-style AR-15 controls are complemented by an ambidextrous-latch charging handle and a manual safety. The pistol grip is a BCM unit, and the trigger is described as curved and polished. The receiver extension is a pistol configuration with a capped end and no stock or brace.
Accessories are already installed, including a tubular red-dot optic on a riser, flip-up backup sights, a handguard-mounted weapon light positioned around 10:30, a small M-LOK handstop, and textured rail panels. The user-applied gray/green camouflage covers the receivers, handguard, and mounted accessories for a unified appearance.
Markings include PA-15 and MULTI on the lower along with Palmetto State Armory, West Columbia, SC, and SAFE/FIRE selector markings. This U.S.-made AR pistol is finished in a gray/green camouflage pattern on its aluminum alloy receivers and handguard.
