About this upper
Precision Reflex MK12 Mod 0 SPR GEN II 5.56MM 18'' Barrel 1-8 Twist Upper FDE is an upper receiver. Finish: Flat Dark Earth.
Manufacturer details
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:
Features
- 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

A note on accuracy. We work hard to keep every listing correct, but specifications, images and compliance details come from many sources and can contain errors or change without notice. Images may show a configuration that is not California-legal. If a detail on this page matters to your decision, call us and we will confirm it against the actual firearm before you order. The compliance information here is general in nature and is not legal advice; California and local laws change, and the configuration described is confirmed at the time of sale.
