The BD3-AK is a 3-port compensator / muzzle brake hybrid for the AK variant rifles that offers recoil reduction for improved comfort and faster follow-up shots. It virtually eliminates recoil and minimizes muzzle movement.
The three lateral chambers reduce the felt recoil and 2 top ports help to eliminate muzzle rise. The upper ports are situated at the muzzle so the full force of the expanding gas will keep the muzzle down for a very flat recoil profile. The horizontal ports use the larger volume of lower pressure gas to reduce the felt recoil.
The additional forward-angled ports at the rear are designed to “blow out” flash and fire that would otherwise plume outwards from the brake’s chamber.
