PRO2A LEFT HAND 20" 6mm ARC 1/7.5 Rifle Length NR Side Charging Melonite M-LOK AR-15 Upper

Description

The Pro2A Tactical Left-Handed 20-inch 6mm ARC Non-Reciprocating (NR) Side Charging Complete Upper Receiver assembly delivers maximum ergonomic control and long-range accuracy for southpaw operators. Built with a heavy-duty, field-verified design in Georgia, this upper combines a true left-hand ejection architecture with an advanced, static side-charger mechanism. Paired with a velocity-optimized 20-inch barrel and smooth-cycling rifle-length gas system, it provides left-handed competitive shooters and long-range hunters with an ultra-rigid, blowback-free drop-in solution.

Key Features

• Left-Handed Non-Reciprocating Charger: Designed with a dedicated left-eject billet upper and a side-mounted charging mechanism that remains static while firing, keeping gas and casings away from southpaw shooters' faces.
• 6mm ARC Ballistics: Engineered to squeeze maximum downrange velocity out of the 6mm Advanced Rifle Cartridge, outperforming traditional chamberings in drop, wind drift, and energy delivery.
• Fast 1/7.5 Twist Rate: Specifically spun to confidently stabilize heavy, high-BC match and modern hunting projectiles for pinpoint sub-MOA capabilities.
• Rifle-Length Cyclic Tuning: An extended direct impingement gas curve reduces internal bolt carrier speeds, decreasing felt recoil and easing mechanical wear during heavy use.
