Crafted from 17-4 PH stainless steel, American-made BlackBore choke tubes feature “knife blade” ports, designed to retard the wad for more consistent, denser patterns, and reduce recoil and muzzle flip. The size, number and positioning of the ports are load-specific, with models available for the range (Competition), light hunting loads (HunterPro LT), heavy hunting loads (HunterPro HV), and buckshot and slugs (HunterPro DR).
BlackBore Tactical HD choke tubes are designed specifically for buckshot and slugs. Competition models are available in bright and matte-stainless steel finishes, as well as black oxide; those for hunting and tactical use are offered in black oxide only. The chokes extend 2 inches beyond the end of the barrel, and the choke constriction options are dependent on the model selected. The company has options for most brands and thread types. Price: $60-$65.
