NERO® 556: Hybrid Muzzle Brake & Compensator

Neutralizing Energy, Remain at Origin

We set off to create the ideal compensating muzzle brake by starting from a blank canvas. Our goal was to completely transform the recoil impulse of the AR-15 into a simple, soft rearward push with zero muzzle climb. Due to the NERO 556's performance characteristics, we highly recommend using a firm but neutral grip when firing (specifically - resist any instinct to pull down on the rifle anticipating muzzle rise).

To achieve our design goal of zero muzzle rise, we had to reject all design constraints and engineer the NERO 556 from the ground up using computational fluid dynamics and direct metal laser sintering (DMLS – also referred to as “3D printed metal”). Leveraging these cutting-edge technologies also allowed us to manufacture a device using Inconel, a nickel-chromium superalloy more at home in rockets and jet engines (learn more about Inconel here), all to produce a muzzle brake that had no peer. Whether combat or competition, the NERO 556 is designed to give you the absolute ideal level of controllability and speed.
