Avian-X Turkey Chokes Features The Avian-X Turkey Choke is engineered around internal groove technology that helps separate shot pellets from the wad immediately after it leaves the muzzle producing denser and more even patterns downrange. Straight rifling inside the tube prevents the wad from spinning as it travels which keeps more pellets concentrated on target instead of spreading into a wider less effective pattern. Castle cuts machined into the crown lock the choke tightly in the barrel while also providing exhaust channels that let propellant gases escape quickly. Together these features are built to deliver maximum kinetic energy on target at the extended ranges turkey hunters often have to work with. This choke is rated to run steel tungsten bismuth and lead loads giving hunters the flexibility to choose the shot material that best suits their shotgun and hunting situation. It is machined to the Winchester Win Choke configuration in 20 gauge so it threads directly into compatible Winchester shotguns without any additional fitting. A black PVD finish protects the choke from the elements and from repeated cycling in the field across long turkey seasons. The Avian-X Turkey Choke gives dedicated turkey hunters a simple effective upgrade over a factory choke for tighter patterns and more consistent performance.
