Kick s Gobblin Thunder Choke Tube Features The Kick s Industries Gobblin Thunder uses a conical parallel design combining a typical cone of constriction with a roughly one inch parallel section that holds the constriction constant. This geometry is paired with exclusive directional diagonal ports angled 135 degrees away from the shooter which create a sharp forward inside edge that grabs and stabilizes the wad. Slowing the wad lets it separate from the shot column faster producing cleaner patterns that are not thrown off by the wad trailing through the pattern. The angled ports also reduce muzzle jump and recoil helping the shooter get back on target faster for a follow-up shot if needed. Because the ports are directional side blast is reduced compared to chokes vented at 90 degrees or less which is a real advantage in tight spaces like duck blinds or five stand bays. The external ported section extends about 1-3/4 inches from the muzzle without being noticeable while shooting and the ports are designed to stay clear rather than fouling up like some competing designs. This .670 constriction is built specifically for the Browning Invector Plus thread pattern in 12 gauge converting a general-purpose bird gun into a dedicated turkey hunting tool. The Gobblin Thunder line carries a competitive pedigree having placed in NWTF still target and Ladies Open shoots.
