The Gobblin Thunder is designed and built in the USA with turkey hunters in mind. Unlike other brands, Kick's manufactures this shotgun choke tube replacement with diagonal ports. These specialized ports slows the wad and efficiently vents gasses which results in improved patterning, reduced recoil and lowered muzzle rise. The next time you're calling in a Tom, be sure to use the Kick's Industries Gobblin Thunder choke tube with your hunting shotgun.
