Key Features
- Blast-Forwarding Flash Can: Linear muzzle device pushes unburnt powder, bright flash, and concussive sound waves straight downrange, dramatically improving shooter comfort—especially during indoor or barricade operations.
- Premium Melonite / Nitride Treated Barrel: The 4150 CMV steel barrel features a uniform liquid QPQ Nitride treatment inside and out for top-tier surface hardness, extreme corrosion protection, and long bore life.
- Versatile 1:7 Twist Rate: The fast rifling twist ensures reliable stability with heavy duty cartridges (62gr to 77gr) while comfortably managing standard 55gr practice ammo.
- Continuous 15" Slim M-LOK Rail: The free-float handguard provides full-length real estate for stable modern hand placements and endless layout options for accessories like lights, optics, or grips.

Why Choose the PRO2A 16" 5.56 NATO Flash Can Upper?
Standard A2 birdcage muzzle devices vent muzzle concussions at 360 degrees, which can distract neighboring shooters at public lanes or cause significant acoustic discomfort under covered roofs. The Pro2A Tactical Flash Can Upper addresses this directly by wrapping the muzzle profile inside a linear redirecting chamber. By pairing this feature with an ultra-durable, easy-to-clean Melonite barrel and a soft-shooting mid-length gas loop, Pro2A provides a flat-cycling system that feels incredibly comfortable to shoot. Whether you are assembling a home-defense rifle or a reliable target setup, this complete, range-tested assembly ensures an optimized, ergonomic shooting experience.
