The PA-15 platform delivers a classic AR-15 configuration with a semi-automatic, direct-impingement operating system. The upper is flat-top with a full-length Picatinny rail for mounting sights, and it includes a forward assist and ejection-port cover. A low-profile, set-screw gas block keeps the sight picture clear and supports the extended handguard.
The 16-inch barrel is threaded and capped with an A2-style birdcage flash hider. The extended free-float aluminum M-LOK handguard offers ample accessory mounting along with a short forward 1913 rail section for front sight or ancillary attachments. This setup helps maintain rigidity while keeping weight forward of the receiver balanced.
Furniture is upgraded with a Magpul STR stock and MOE grip in FDE. The STR provides a collapsible, adjustable length of pull and an enhanced cheek weld, pairing function with comfort. The MOE grip complements the stock with a secure, repeatable hold.
Polymer flip-up front and rear sights are installed, so the rifle is ready to zero out of the box. It accepts standard AR-15/STANAG magazines and includes one 30-round PMAG. Controls are familiar and straightforward, including a manual safety selector. Receiver construction is aluminum alloy with a black anodized finish, made in the United States.
