PRO2A 5" 300 Blackout Micro Length Melonite AR-15 Upper with Flash Can Kit

PRO2A 5" 300 Blackout 1/5 Micro Length Melonite AR-15 Upper with Flash Can Kit

Product Description

The PRO2A 5" 300 Blackout Micro Length Melonite M-LOK Upper Kit with Flash Can delivers an ultra-compact, hard-hitting solution for personal defense weapon (PDW) configurations. Engineered around a highly specialized 5-inch barrel with an ultra-fast 1/5 twist rate, this micro system is built to maximize stabilizing rotational torque on heavy subsonic projectiles. It comes standard with a linear blast-forwarding Flash Can tucked cleanly inside the free-float handguard rail, a premium full-auto bolt carrier group, a full lower parts kit, and a stock completion assembly to turn any standard stripped lower receiver into a functional micro platform.

Key Features

Ultra-Fast 1/5 Twist Rate: Delivers maximum stabilization for heavy-grain subsonic loads out of an ultra-short barrel profile to prevent keyholing or baffle strikes.
Blast-Forwarding Linear Flash Can: Mitigates severe lateral concussion by forcing explosive muzzle gases, flame, and auditory signatures downrange away from the shooter.
Micro PDW Footprint: Exceptional compact maneuverability ideal for tight close-quarters tactical environments and discrete vehicle storage.
Premium All-Inclusive Build Package: Bundles your high-accuracy upper assembly with a full nitrided BCG, complete small lower receiver parts, and an adjustable stock completion system.
