PRO2A 16" 9mm 1/10 Pistol Caliber Melonite M-LOK AR-15 Upper with Flash Can
Product Overview
Optimize your Pistol Caliber Carbine (PCC) assembly with the PRO2A 16" 9mm 1/10 Pistol Caliber Melonite M-LOK AR-15 Upper with Flash Can. This premium, factory-assembled complete upper receiver group is engineered to deliver unmatched blowback cycling reliability and linear blast management. Built with a full-length 16-inch 4150 CMV Melonite barrel housed within a continuous 17-inch free-float M-LOK rail, this upper features a slimline linear flash can that cleanly redirects concussion away from the operator.
Key Features
- Blast-Forwarding Flash Can: Linear muzzle device safely channels muzzle concussion, expanding gases, and debris straight downrange, drastically improving physical comfort at indoor or covered lanes.
- Duty-Grade Melonite Finished Barrel: Crafted from heavy-duty 4150 CMV steel and finished inside and out with a liquid QPQ Nitride/Melonite layer for maximum surface hardness and elite corrosion resistance.
- Precision 1:10 Twist Rate: The specialized rifling twist stabilizes standard 9x19mm Luger cartridges across all major grain weights, ensuring excellent consistency with 115gr, 124gr, and heavy 147gr subsonic rounds.
- Extended 17" Slim M-LOK Handguard: Shrouds the barrel completely and seamlessly exposes the crown of the flash can, offering maximum grip space and endless modular real estate for optics, weapon lights, or hand stops.
- Slick-Side Forged Upper Receiver: Precision machined without a traditional forward assist or standard rifle gas tracks, delivering a clean profile optimized explicitly for blowback pistol caliber configurations.
- Complete Operational Readiness: Arrives fully headspaced and factory range-tested.

Why Choose the PRO2A 16" 9mm Flash Can Upper?
Assembling a 16-inch 9mm AR rifle provides the velocity benefits and legal compliance of a full rifle stock, but direct blowback operations generate significant acoustic pressure inside covered environments. The Pro2A Tactical Flash Can Upper Assembly resolves this directly by wrapping the muzzle profile inside a dedicated linear redirection chamber. By mating this feature with a factory-tuned, ramped 9mm bolt carrier group and an easy-to-clean Melonite-treated barrel, Pro2A eliminates the headache of stacking component tolerances. Whether you are assembling a low-recoil home-defense rifle or a competitive target companion, this range-tested assembly provides a smooth, ergonomic, and reliable workflow out of the box.
