Carlson’s 12 Gauge Improved Cylinder Flush-Mount Choke for Winchester Invector

The Carlson’s Improved Cylinder Choke Tube (brand part no. 12212) is a flush-mount 12-gauge choke built for Winchester Invector-pattern shotguns. Carlson’s machines the tube from 17-4 stainless steel and bores it to a .720-inch diameter for an Improved Cylinder constriction, opening the pattern wide for close-range upland flushes and clays. Because it sits flush with the muzzle, there is no extension to snag brush or a gun case lining. It is rated safe for steel, lead, copper-plated lead, nickel, Hevi-Shot, and bismuth loads, and also fits Mossberg Accu-Choke and Weatherby shotguns using the same thread pattern.
