Patriot Ordnance Factory LMR Base Features The Patriot Ordnance Factory LMR Base is chambered in .308 Win and built around a 16.5 premium 416R stainless steel barrel with a 1:8 twist and 6R right-hand lands and grooves a combination tuned for consistent accuracy across a wide range of .308 loads. The barrel carries 5/8x24 muzzle threads under an A2 flash hider giving the rifle a path to a suppressor or muzzle device without further gunsmithing. A mid-length gas system paired with a black nitride low-profile non-adjustable gas block keeps the action running reliably while reducing unnecessary complexity. The aluminum billet forged upper and lower receivers are hard anodized black finished to MIL-A-8625F Type III Class 2 standards for a durable corrosion-resistant surface. Inside a premium Black Nitride KeyLock bolt carrier group with a roller cam pin reduces wear on critical moving parts while keeping the action running smoothly shot after shot. A 15 aluminum M-LOK rail system provides a MIL-STD 1913 rail at the 12 o clock position for optics with additional M-LOK mounting interfaces at the 3 6 and 9 o clock positions for accessories. The rifle ships with a Mission First Tactical Minimalist collapsible stock an A2 pistol grip a mil-spec trigger group and a mil-spec charging handle plus one 20-round Magpul PMAG.
