Abstract: Disclosed is a manifold device containing two equidistant manifold openings which adapt to shotgun chokes to counteract muzzle rise, felt recoil, and muzzle blast in addition to the selectable shotgun choke which controls the shot pattern. The two manifold openings are located in the upper 180 degree portion of the manifold to counteract forces by discharging gases substantially upwards and backwards. A manifold saddle with sufficient curvature for accommodating a second barrel can be utilized for double barrel weapons. The manifold is held in place to maintain the upper 180 degree direction by a choke stop, clamp, or other attachment.
