Patriot Ordnance Factory P-15 Base Features The Patriot Ordnance Factory P-15 Base is built around a Mil-spec P-15 receiver set paired with a match grade 16.5 barrel chambered in 5.56 NATO delivering both accuracy and reliability from a 100 percent American made platform. The bolt carrier group uses POF s patented Roller Cam Pin design to ensure smooth operation and reduced wear over extended use. An A2 flash hider caps the 1/2x28 threaded muzzle controlling muzzle flash while leaving the threads ready for a compensator or suppressor. The Mil-spec trigger provides a reliable predictable pull suited to both range training and duty use. An anti-tilt 6 position buffer tube pairs with a Mission First Tactical adjustable stock letting shooters dial in length of pull for a personalized fit across different body types and gear setups. The 15 M-LOK handguard provides a full length Picatinny rail at the 12 o clock position along with multiple mounting interfaces at 3 6 and 9 o clock for lights lasers or bipods. The entire receiver set and handguard wear a Black Anodized finish that resists wear and corrosion through hard use. Weighing just 6.30 pounds the P-15 Base gives shooters a light reliable rifle that can be upgraded piece by piece as their needs evolve.
