Product Overview
Revolutionize your pistol caliber carbine with the PRO2A 16" 9mm Non-Reciprocating (NR) Side Charging Melonite M-LOK Upper with Flash Can. This fully assembled upper receiver group combines high-tier ergonomics with an integrated blast-forwarding design. Engineered around a premium Gibbz Arms Billet Upper Receiver and a rugged 16-inch 4150 CMV Melonite barrel, this configuration features a left-side charging system that remains completely stationary while firing. It drops straight onto any standard 9mm AR-15 lower receiver setup.
Key Features
- Non-Reciprocating Side Charging Handle: The genuine Gibbz Arms left-side charging system stays stationary while firing, providing superior mechanical leverage and eliminating interference with optics.
- Blast-Forwarding Flash Can: Linear muzzle device pushes unburnt powder, bright flash, and concussive sound waves straight downrange, drastically 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.
- Precision 1:10 Twist Rate: Precision button rifling is dialed in to accurately stabilize a massive range of 9mm munitions, including standard 115gr, 124gr, and heavy subsonic 147gr loads.
- Continuous Slim M-LOK Rail: The free-float handguard provides a continuous top Picatinny rail and clear modular slots for accessories like tactical lights, hand stops, or optics.
- Complete Out-Of-The-Box Reliability: Fully assembled, headspaced, and test-fired at the factory.

Why Choose the PRO2A 16" 9mm NR Side Charging Upper?
Standard blowback 9mm AR configurations can sometimes introduce annoying gas blowback and harsh muzzle blast under covered ranges. The Pro2A Tactical 16" 9mm Upper Assembly addresses this directly by routing the blast away from your face with a slimline linear flash can. Combined with the high-end ergonomics of a premium Gibbz Arms side-charging handle, manual manipulation becomes incredibly fluid. You no longer need to break your cheek weld or clear oversized scopes to cycle the bolt. Factory range-tested with a perfectly headspaced 9mm bolt group and a match-ready Melonite barrel, this complete upper delivers a smooth, clean-shooting, and premium workflow optimized for competitive PCC matches or defensive configurations.
