The Carlson’s Improved Modified Choke Tube (brand part no. 12214) 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 .705-inch diameter for an Improved Modified constriction, tightening the pattern beyond standard Modified for longer-range work while staying more open than a Full choke. 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.
