Carlsons 20 Gauge Flush Mount Extra Full Choke Tube - Winchester Invector - 17-4 Stainless Steel

The Carlsons Flush Mount Extra Full choke tube is a precision-engineered replacement choke for 20 gauge shotguns chambered for the Winchester Invector choke system. Proudly manufactured in the USA from solid 17-4 stainless steel, this choke is CNC milled and heat-treated for the long service life Carlson shooters have come to expect.

Rated at Extra Full (X-Full) constriction with a .585 in diameter, this choke delivers the tight, dense shot patterns favored for long-range turkey and waterfowl hunting, as well as pass shooting. The flush-mount profile keeps the muzzle contour clean and snag-free in the field, while the knurled end allows for quick, tool-free hand installation and removal.

Designed as a direct replacement for damaged, worn, or missing factory chokes, this Carlsons 20 gauge flush mount choke fits any shotgun using the Winchester Invector pattern. From patterning sessions to the hunt, it produces consistent, uniform shot columns shot after shot.
