Extended choke with diagonally-ported design for recoil reduction. Conical/parallel internal configuration.
Easy to install and remove with your fingers. No special wrench or tool required.
Fits 20g barrels with Remington Probore style threads.
Remington has multiple thread types that are not interchangeable with one another. It's very easy to tell which choke type you need. If your threads are at the end of the barrel, you need the Probore style chokes. If your threads are recessed, you need the Remington style chokes instead.
To ensure that you receive the correct chokes, it is important that you compare your existing chokes with the measurements and photographs provided on this page.
