The Patriot Ordnance Factory P-15 Base SMU Rifle (brand part no. 02549) is a .300 AAC Blackout semi-automatic AR-15 pattern rifle built around POF-USA’s 7075-T6 aluminum P-15 receiver set, finished in Olive Drab Cerakote for a durable, low-profile look. Patriot Ordnance Factory machines a 13.75-inch black nitride match-grade barrel and permanently pins and welds a muzzle device to it, bringing the total barrel length to 16.1 inches — keeping this a standard Title I rifle with no NFA paperwork or transfer wait, while still giving the compact handling of a shorter true barrel. A Picatinny top rail and M-LOK handguard provide mounting space for optics and accessories, and an Amend2 adjustable stock lets shooters dial in length of pull. Among our AR rifles, the P-15 Base SMU suits .300 Blackout shooters who want compact handling without the wait and paperwork of an NFA-registered short-barreled rifle.
