Patriot Ordnance Factory P-15 Base SMU Features The Patriot Ordnance Factory P-15 Base SMU is built around 7075-T6 aluminum upper and lower receivers anodized Black for durability against wear and corrosion. A direct impingement operating system cycles the action using a bolt carrier group with Patriot Ordnance Factory s patented roller cam pin which reduces friction and wear on the cam pin track over extended use. The 13.75 inch Match Grade barrel is finished in Black Nitride for corrosion resistance and comes paired with a pinned and welded Dead Air KeyMo muzzle brake bringing the overall barrel length to 16.10 inches. Chambered in .300 AAC Blackout the rifle feeds from 30 round magazines and cycles reliably across both supersonic and subsonic loads thanks to its 1 in 7 inch twist barrel. An anti tilt six position buffer tube pairs with an Amend2 adjustable stock to let shooters dial in length of pull for different body types or gear setups. The flared magwell speeds up magazine changes under time pressure while the Amend2 grip and Mil-Spec trigger round out the ergonomics package. A full length Picatinny top rail runs the length of the upper receiver for mounting optics and the 13 inch M-LOK handguard provides ample real estate for lights grips or bipods. At 6.30 pounds the P-15 Base SMU stays maneuverable while delivering the ruggedness Patriot Ordnance Factory rifles are known for and it is available for sale at GrabAGun for shooters who want a dependable .300 Blackout platform.
