The Patriot Ordnance Factory P415 complete upper is a piston-driven 5.56x45mm NATO upper receiver built on decades of combat-proven design refinement. POF's piston system has earned its reputation for reliability across demanding environments—whether you're running suppressed, in extreme climates, or logging serious round counts at the range. This complete upper pairs that robust operating system with a 16.50" black nitride barrel and aluminum black anodized receiver, giving you a compact, corrosion-resistant platform ready to accept any compatible lower.
The 14.50" M-LOK handguard is engineered for both shootability and weight management. At just 1.75 inches wide, it keeps the upper slender and handy without sacrificing rail real estate for mounting optics, lights, or other accessories. If you're building a rifle for hunting, tactical training, or general-purpose shooting, this upper handles suppressor-ready barrels and pairs easily with any standard AR-pattern lower receiver.
POF's E2 Extraction Technology and fully ambidextrous controls (on the complete rifle platform) represent the company's continuous evolution since the P415 platform debuted. You're getting the benefit of that refinement in a no-frills, purpose-built upper that prioritizes function over marketing noise.

This is a complete upper receiver assembly designed for any standard AR-pattern lower receiver. It's a direct-drop fit with no modifications needed.
The 16.50" barrel is compatible with suppressors, but this listing does not specify whether the barrel features a threaded muzzle or what thread pitch may be included. Verify muzzle configuration before purchasing a suppressor.
Piston-driven uppers cycle cleaner and run cooler than direct-impingement designs, reducing fouling and extending service life—especially valuable if you run suppressors or shoot high round counts.
Yes. The M-LOK handguard and receiver are designed to accept standard AR-pattern rail accessories. The handguard provides plenty of real estate for mounts without adding bulk.
