Description

The Pro2A Tactical 10.5-inch 10mm Auto Non-Reciprocating (NR) Side Charging Complete Upper Receiver assembly extracts the absolute maximum ballistic performance and ergonomic control from the AR-10mm platform. Hand-assembled and quality verified in Georgia, this premier system upgrades your layout by replacing the traditional rear charging handle with an advanced, static side-charger mechanism. Utilizing an extended 10.5-inch Melonite barrel calibrated to squeeze optimal velocity thresholds and improved downrange foot-pounds of energy out of full-power heavy loads, it provides a flawless drop-in solution for personal defense, home security configurations, or backcountry wilderness protection.

Key Features

• Non-Reciprocating Side Charging: Enhances manual charging ergonomics with a side-mounted handle that remains fully static while cycling, preventing optics obstruction and maximizing leverage from standard shooting positions.
• Maximized 10.5" Velocity & Energy: The extended 10.5-inch barrel length significantly improves powder burn efficiency compared to micro setups, delivering optimal downrange ballistics out of the 10mm Auto cartridge.
• Straight Blowback Reliability: Engineered completely without traditional gas blocks or gas tubes, dropping complex wear points to guarantee steady feeding and extraction cycles with heavy loads.
• Premium Melonite Hardness: 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.
