Description
Precision Reflex’s Mark 12 Mod 0 SPR Gen II Upper Receiver is a complete, full-featured tactical upper that’s fully assembled and ready to shoot…once you install it on a mil-spec lower receiver. It is fitted with PRI’s Gen II Retro Carbon Fiber Forend that replicates the handguard of the U.S. Navy’s Mk 12 Mod 0 Special Purpose Rifle. You get a mile-long, uninterrupted expanse of Picatinny top rail extending from the rear of the receiver to the front of the forend. (Maybe we exaggerate slightly – half a mile.) There are also short 3″ lengths of Picatinny rail up front in the 3, 6 and 9 o’clock positions. The Mark 12 Mod 0 SPR Gen II Upper Receiver will deliver MOA accuracy right out of the box thanks to its free-floated, 18″ Douglas barrel of high-grade 416 stainless steel with 1-7″ target rifling and M4-type feed ramps. The bolt is custom-fitted to the barrel. And as the late-night infomercials say, that’s not all. The SPR Gen II upper also offers: PRI Gas Buster charging handle with an easy-to-grasp oversized latch Precision Reflex Flip Up sights – elevation (front) & windage (rear) adjustable without tools OPS muzzle brake to tame recoil & muzzle rise during rapid fire 5.56x45mm NATO chamber accepts both military & civilian .223 Remington ammunition Rifle-length gas system cuts gas velocity to promote excellent reliability Non-reflective matte black finish on barrel, brake, receiver & forearm The PRI Mark 12 Mod 0 SPR Gen II Upper Receiver delivers a unique combination of accuracy, performance, and versatility, but it’s pleasantly basic where it counts. The forged, mil-spec AR-15 flattop receiver comes with a standard commercial carrier, so compatibility with a mil-spec (.250″ pivot/takedown) lower is no problem.
