Kick's Gobblin Thunder Turkey Choke Tube for 12 ga Winchester .655 SPECIFICATIONS BRAND: KICK'S INDUSTRIES BRAND FAMILY: GOBBLIN THUNDER CA PROP 65: YES CHOKE DIAMETER: .655 COLOR: BLACK GAUGE: 12 GA WEAPON MFG: WINCHESTER DESCRIPTION All of Kick's chokes feature a conical parallel design. This refers to the cone of constriction (typical) coupled with a parallel section (rarely found in other chokes) of roughly 1" where the constriction is held constant. Kick's combines this design with their exclusive directional* diagonal ports that because of their outward angle create a sharp forward inside edge which grabs, stabilizes and slows the wad for faster separation of wad and shot column. This results in cleaner patterns not adversely affected by the wad. The diagonal ports also reduce muzzle jump and recoil for faster, more accurate follow up shots. The external ported portion of the chokes extends roughly 1 3/4" from the muzzle and isn't noticable when shooting. *Directional- The angle of the ports is 135 degree away from the shooter, reducing side blast prevalent in ports 90 degree or less. This is a big plus for close quarters like duck blinds, trap fields and five stand. The ports also stay clear and don't foul up like others. The Gobblin' Thunder is a two-time winner of the NWTF still target shoot in Atlanta, GA. The Gobblin' Thunder is also a two-time winner of the NWTF Ladies Open Competition and the 98 winner of the Jakes competition.Kick's has also captured many grand slam hunts. Gobblin' Thunder easily converts most 10 & 12 gauge factory-threaded barrels from a mild-mannered bird gun into a turkey hunting specialist.
