Product Overview

The PRO2A 7.5" 223/5.56 Pistol Length Upper Kit provides an ergonomic and reliable solution for ultra-compact AR-15 platforms.

Why Choose the PRO2A Side Charging 5.56 Blast Can Kit?

Tuning a short-barrel pistol system can be notoriously challenging due to increased concussive blast and cycling speeds. The PRO2A Tactical upper layout addresses these pain points perfectly. By pairing a high-grade 7.5-inch Melonite barrel with an integrated forward-facing flash can, concussive pressure is directed safely downrange instead of blowing back into your face. Combined with a smooth, rigid non-reciprocating billet side-charging design, manual clearing operations become lightning-fast. Built entirely in the USA by professional armorers, this comprehensive kit ensures uncompromised reliability and elite ergonomics out of the box.
