The Carlson’s Extra Full Choke Tube (brand part no. 12216) 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 .690-inch diameter for an Extra Full constriction, the tightest pattern in the standard lineup for maximum reach on turkey or long-range waterfowl. Because it sits flush with the muzzle, there is no extension to snag brush or a gun case lining. It is rated safe for lead, copper-plated lead, nickel, Hevi-Shot, and bismuth loads, but is not intended for use with steel shot.
