Kick s Gobblin Thunder Choke Tube Features The Kick s Gobblin Thunder Choke Tube is machined from 17-4PH stainless steel and chemically blackened for a durable corrosion-resistant finish that holds up to repeated field use. Its interior combines a conical and parallel design that is unique to this choke working the shot column to produce denser and more consistent patterns than a standard constriction. Sized to a .685 restriction it is specifically recommended for 3.5 shells loaded with #4 lead shot matching the choke to serious turkey hunting applications. The round angle-ported extension measures approximately 1.5 long extending visibly past the muzzle while cutting down on recoil and muzzle jump with every shot fired. Threaded for the Browning Invector Plus pattern the Gobblin Thunder installs and removes without a wrench letting a hunter swap chokes quickly in the field or at home. The extended ported design not only tames recoil but also helps keep the muzzle settled for a faster recovery between shots which matters when a follow-up shot on a gobbler counts. Sizing is based on the choke s inside diameter measurement giving hunters a clear consistent reference when selecting the right constriction for their load. For turkey hunters running a Browning Invector Plus shotgun who want tighter patterns and reduced recoil the Kick s Gobblin Thunder Choke Tube is available for sale at GrabAGun.
