PRO2A 5" 9mm 1/10 Pistol Caliber NR Side Charging Melonite M-LOK Upper

Description

The Pro2A Tactical 5-inch 9mm Non-Reciprocating (NR) Side Charging Complete Upper Receiver assembly delivers maximum compact speed and handling efficiency to the AR-9 micro platform. Assembled by hand and verified for tight quality specs in Georgia, this system upgrades the traditional platform by replacing the rear charging handle with an advanced, static side-charger mechanism. Featuring an ultra-short 5-inch Melonite barrel operating on a dependable blowback system, it provides a premium drop-in solution for micro pistol builds, personal defense setups, or compact truck guns.

Key Features

• Non-Reciprocating Side Charging: Upgrades weapon manipulation with a side-mounted handle that remains static while firing, preventing optic mount interference and keeping your eyes fixed on target.
• Micro-Compact Footprint: Outfitted with an ultra-short 5-inch barrel configuration that offers maximum maneuverability and quick transitions in close-quarters applications.
• Straight Blowback Action: Built without gas blocks or gas tubes, dropping complex wear points to guarantee steady feeding and extraction cycles with standard 9mm ammunition.
• Premium Melonite Treatment: The 4150 steel barrel is treated inside and out with an ultra-hard Melonite finish, providing extreme corrosion resistance and an easily cleaned bore surface.
