PRO2A 8.5" 300 Blackout 1/7 Pistol Length NR Side Charging Melonite M-LOK AR-15 Upper with Flash Can Kit
Product Overview
The PRO2A 8.5" 300 Blackout 1/7 Pistol Length NR Side Charging Melonite AR-15 Upper with Flash Can Kit delivers the ultimate close-quarters compact performance package for the versatile AR-15 platform. Built around a precision 8.5-inch 4150 CMV barrel, this complete upper build configuration maximizes powder burn efficiency and muzzle velocity for the hard-hitting .300 AAC Blackout cartridge. Featuring a premium Non-Reciprocating (NR) side-charging handle to optimize weapon manipulation under optics and paired with an integrated muzzle flash can to throw heavy pressure waves downrange, this complete conversion kit stands ready to drop directly onto your choice of mil-spec lower receivers.
Key Features
Non-Reciprocating Side Charging Action: Handle remains locked forward and completely stationary during cycling sequences to eliminate shooter distraction and clear wide optic setups.
Blast-Directing Linear Flash Can: Correctly redirects concussive blast profiles, hot gas expansion, and noise forward away from the operator during close-quarters firing.
Optimized Pistol-Length Gas Port: Tuned gas dwell times supply the exact backpressure tolerances needed to reliably cycle both supersonic hunting cartridges and heavy subsonic grain loads.
Rigid Melonite/QPQ Barrel Defense: High-rigidity liquid-nitride lining increases surface thickness, maintains bore accuracy, and guards against harsh field elements.
All-In-One Assembly Package: Fully includes the crucial bolt group, lower lower parts group, and blade stabilization gear required for immediate frame integration.
