Key Features

Complete Build Integration: Bundles your high-accuracy upper assembly, full nitrided BCG, small completion parts, and an adjustable stock system into a singular package.
Blast-Forwarding Linear Flash Can: Mitigates lateral concussion and directs high-pressure hot gases, muzzle flash, and auditory signatures cleanly forward toward your targets.
Smoother Mid-Length Cycling: Utilizes an optimal gas port distance to reduce system pressure, slide velocity, and mechanical wear over high-volume firing schedules.
Premium Melonite Structural Treatment: Crafted from 4150 CMV steel liquid nitrided to grant superb protection against environmental elements, uniform heat displacement, and enhanced longevity thresholds.
