The PA-15 uses a direct impingement, semi-automatic system with a carbine-length gas setup for a familiar AR-15 handling profile. The 16-inch M4-profile barrel is threaded and capped with an A2-pattern birdcage flash hider. Its 1:7 twist is well-suited to standard 5.56 NATO bullet weights.
The upper is a flat-top (A3) design with an integral Picatinny rail, forward assist, brass deflector, and dust cover. A fixed A2 front sight base is installed; no rear sight is included. The front sight base also features a bayonet lug and a forward sling swivel.
Furniture is Flat Dark Earth polymer, including a two-piece, ribbed carbine-length handguard, an A2-style grip, and a 6-position collapsible stock with a rear sling loop and PSA crest. Length of pull measures approximately 10 inches (collapsed) to 13.5 inches (extended).
The receivers are aluminum with a matte black anodized finish. Controls include a standard right-side magazine release and a manual safety. Notable details include an upper forging code "A" and U.S. manufacture.
Capacity is 40+1 with the included Magpul PMAG GEN M3 40-round magazine. This setup pairs the classic A2 front sight with the flexibility of a flat-top upper while retaining a clean, excellent-condition bore and chamber.
