The Pro2A Tactical 12.5-inch 5.56 NATO Non-Reciprocating (NR) Side Charging Complete Upper Receiver assembly featuring an integrated linear Flash Can maximizes tactical maneuverability, handling speed, and blast mitigation on the AR-15 platform. Hand-assembled and quality verified in Georgia, this premier system replaces the traditional rear charging handle with an advanced, static side-charger mechanism.

Stepping away from traditional over-gassed carbine setups on short barrels is crucial for structural cycling performance. The Pro2A 12.5" 5.56 NATO NR Side Charging Upper with Flash Can addresses this design vulnerability entirely by matching its premium billet architecture to an extended mid-length direct impingement gas system and a forward-directing linear muzzle layout. The static side-charging handle yields crucial clearance for modern, oversized optics while maximizing operational speed from prone positions. Built with professional case-hardening surface treatments to preserve bore life and guarantee effortless maintenance, it is the ultimate option for tactical operators demanding maximum custom-tier rigidity in a drop-in package.
