Carlson's High Quality Replacement Choke Tubes are the ideal upgrade to lost, damaged, worn or old factory supplied choke tubes. These Replacement Choke Tubes are flush-fitting and come with a free Choke Wrench.

Carlson's Choke Tubes are manufactured from high-strength 17-4 Stainless Steel for use in all weather conditions, and are designed to throw tight, dense patterns.

All Carlson's Choke Tubes are designed to shoot any Lead, Copper-Plated, Nickel-Plated, Bismuth, Hevi-Shot, Hevi-Metal or Tungsten shot shell loads.

Slugs and Sabot Slugs are not to be fired through any choke with a constriction tighter than Improved Modified. Do not shoot steel shot larger than BB or any steel shot shell load faster than 1550 fps through a Full Choke. Shot sizes BB, T, and F should not be fired through any choke tube tube tighter than Modified.

Remember to pattern your shotgun with the specific shotshell load you will be using during your hunt. Different brands of ammunition throw different patterns from the same choke tube.

This choke tube is compatible with early Winchester shotguns using Win-Choke choke tubes, Mossberg 500 Shotguns and early Browning Shotguns using Standard Invector chokes.

Shotguns using Invector Plus chokes, such as new Winchester and Browning shotguns are not compatible with this choke. New Browning A5's use Invector DS chokes.
