Genuine Remington Choke Tube. Remington's factory Rem Chokes are a system of interchangeable choke tubes and extended chokes that allow you to quickly and easily change the choke of your shotgun to match specific hunting conditions. Performance tuned for all Remington shotguns in field and target constrictions for optimal pattern performance.
Note: There are two kinds of Chokes for Remington Shotguns. Rem Choke and ProBore. If you don't know which your gun uses simply screw it out and look at the threads. Rem Choke threads are near the back of the choke tube ( look at picture of a Rem Choke tube here on the store). ProBore threads near the front of the choke tube ( look at picture of a ProBore Choke here on the store).
