PRO2A 7.5" 223/5.56 1/7 Pistol Length Melonite M-LOK Upper with Flash Can

PRO2A 7.5" 223/5.56 1/7 Pistol Length Melonite M-LOK AR-15 Upper with Flash Can

Product Overview

The PRO2A 7.5" 223/5.56 1/7 Pistol Length Melonite M-LOK AR-15 Upper with Flash Can offers a highly compact, optics-ready tactical upgrade engineered for maneuverability and rapid deployment. Chambered dynamically in 223 Wylde / 5.56 NATO, this pre-assembled barreled upper matches a premium 7.5-inch heavy profile barrel to an integrated project-forward linear Flash Can device. By extending the free-float M-LOK handguard past the muzzle threads, the flash can sits cleanly tucked inside the rail system, driving aggressive muzzle expansion and blast concussions straight downrange. Meticulously headspaced and timed, this premium upper system attaches directly to any standard mil-spec AR-15 lower receiver setup.

Key Features

Tucked Linear Flash Can: Drives aggressive short-barrel muzzle blast, expanding gases, and heavy concussive acoustic shock waves directly forward away from the operator.
Compact 7.5-Inch Profile: Yields fast structural index transitions and handling speeds in close-quarters personal defense environments, vehicles, or tight spaces.
Precision 1/7 Twist Optimization: Land-and-groove button rifling configuration engineered to perfectly stabilize standard and heavy 55gr to 77gr defensive payloads cleanly.
Inside-Out QPQ Melonite Hardening: High-performance liquid salt-bath nitride surface treatment preserves uniform land alignment against high-velocity gas erosion while providing total resistance to moisture corrosion.
Extended Slim M-LOK Rail: Free-floating aluminum handguard design isolates barrel harmonics to protect shot-to-shot groupings while fully wrapping the flash can for a streamlined look and maximum accessory mounting real estate.

Why Choose the PRO2A 7.5" Tucked M-LOK Upper?

Running an ultra-short 7.5-inch barrel setup on the AR-15 platform introduces brutal muzzle flash and massive horizontal concussive shockwaves that make standard flash hiders uncomfortable to operate. Pro2A Tactical counteracts this obstacle on the bench by matching a precision-machined, ultra-hard 7.5" Melonite heavy barrel to a dedicated slimline project-forward linear flash can. By fully tucking the blast device beneath an extended free-float M-LOK handguard, this assembly provides a seamless look that safely pushes the concussive pressure envelope away from your hands and face. Engineered to prevent internal tolerance stacking and built with premium 4150 CMV steel, this upper receiver assembly eliminates the cycling headaches often found in custom short-barrel builds, ensuring immediate drop-in performance right out of the box.
