Kick s Gobblin Thunder Choke Tube Features The Kick s Gobblin Thunder Choke Tube is machined from 17-4PH stainless steel and chemically blackened giving it a tough corrosion resistant finish for repeated field use. Its 18 angle ported design distributes gas pressure around the upper 270 degrees of the tube helping stabilize the shot charge and reduce both recoil and muzzle jump. The unique conical parallel interior geometry is engineered to produce denser more consistent turkey patterns compared to a standard choke. At .570 constriction this choke is purpose built for 3 loads of #4 lead shot a common turkey hunting combination. Extending approximately 1.5 from the barrel the Gobblin Thunder requires no wrench for installation or removal making it easy to swap in the field. It is threaded specifically for the Crio and Crio Plus choke system found on Benelli 20 gauge shotguns ensuring a secure precise fit. The choke will safely pattern projectiles up to .30 caliber giving turkey hunters confidence in a wide range of shot sizes within its intended use. Turkey hunters looking to tighten their pattern and improve consistency at extended range will find the Gobblin Thunder a worthwhile upgrade.
