Product Description

The PRO2A 13.7" 5.56 NATO Mid Length Melonite M-LOK Upper Receiver Assembly with Flash Can is meticulously engineered to achieve the absolute shortest legal rifle profile possible without the need for federal NFA short-barreled rifle registration. This specialized upper features an extended linear blast-forwarding Flash Can permanently pinned and welded to the barrel, satisfying the legal 16-inch civilian length requirement. Utilizing a smooth-cycling mid-length gas layout and a premium modular free-float handguard that encompasses the recessed muzzle setup, it drops instantly onto any standard AR-15 lower receiver to provide an incredibly well-balanced and flat-shooting defensive assembly.

Key Features

• Non-NFA Legal Compliance: Ultra-short 13.7-inch barrel is permanently extended past the standard civilian 16-inch threshold using a clean, professional pin-and-weld muzzle attachment procedure.
• Blast-Forwarding Linear Flash Can: Mitigates harsh lateral concussion and directs explosive powder gasses, flame, and raw muzzle report completely forward downrange away from the operator.
• Smoother Mid-Length Gas Profile: Implements an optimized gas port distance to drop cyclic pressures and bolt slide speed, resulting in significantly smoothed out recoil and minimized mechanical wear.
• Premium Melonite Structural Defense: Heavy-duty 4150 CMV steel is thoroughly liquid nitrided to secure supreme environmental corrosion resistance and a longer bore throat life.
