Muzzle Device

A2 Style Flash Hider or Compact Muzzle Brake? While mostly a matter of looks or preference, some states have outlawed A2 Style Flash Hiders or consider them to be "evil features", contributing toward what may or may not be considered an "assault rifle" under the definition of state law. Be sure to read and understand your local laws.

Aside from the legality, there are benefits in looks and performance when choosing a Compact Muzzle Brake. Muzzle brakes, besides looking cool, divert the gasses exiting the barrel in such a way that reduces recoil and muzzle rise, and can improve follow-up shot accuracy.

Don't forget to add one of our 80% Lower Jigs, the fastest and easiest way to finish your 80% Lower at home!
