Patriot Ordnance Factory Upper Receivers

Find a complete selection of POF upper receiver assembly units, including P 415 upper receiver assemblies and Patriot Ordinance Factory 308 upper receivers. Our line of POF-USA complete upper receiver assemblies and Gen 4 short-barreled units don't require an FFL for purchase. These include a 7.25” regulated gas piston operated (five-position adjustable) semi-auto that chambers a 5.56mm NATO round and comes with either a black or NP3 finish or one with a 10.5” barrel that shoots the same ammo and comes in the same finish options. Both of these POF gas piston upper assemblies have flash hiders and heavy contour fluted barrels.

We're offering two brand-new P415 upper receiver assemblies that both shoot 6.8mm SPC II rounds and have 16.5” barrels. The Edge model has a five-position adjustable gas piston and a nitrated 11:1 twist barrel that's match grade fluted. It also has a triple port muzzle break and comes with a hard coat black anodized finish. The other P415 being offered has an NP3 finish.

Our lineup of Gen 4 P308 upper receivers includes those with 12.5” barrels, 14.5” barrels, 16.5” barrels and 20” barrels. All have the new E-Square Chamber and shoot 7.62mm (308) rounds. The 14.5” model has a fixed flash hider that brings its overall length to 16”.
