These choke tubes are compatible with shotguns using Win-Choke thread size and fit a variety of brands including Remington, Beretta/Benelli, and Mossberg 835 Ultra Mag.
The tubes are constructed from stainless steel, are heat treated, and can be used with magnum and steel shot loads. However, X-Full and Turkey constrictions should only be used with Lead and Hevi-Shot.
Available in 12 and 20 gauge sizes, the Win-Choke-style tubes have specific thread per inch measurements to match barrels originally equipped with compatible choke systems.
