Carlson’s 20 Gauge Cylinder Flush-Mount Choke for Winchester Invector

The Carlson’s Cylinder Choke Tube (brand part no. 10107) is a flush-mount 20-gauge choke built for Winchester Invector-pattern shotguns. Carlson’s machines the tube from 17-4 stainless steel and bores it to a .620-inch diameter for a Cylinder constriction, the most open pattern in the lineup for very close-range work like home defense or dense-cover upland hunting. 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.
