This super full Turkey Choke Tube has been specifically formulated for Ultimately tight patterns. It features a ported, knurled fore-end for easy installation in the field under any condition, without tools. The porting drops gas pressure at the muzzle, helping ease the wad away from the shot, reduced recoil, and dampen muzzle jump. The choke tubes feature internal axial rings to keep the shot cloud on target. The tubes are forged from aircraft stainless steel for years of carefree use, and finished in matte black for concealment.
