I assume you are talking about choke tubes. The Browning tube (not their Invector, but their earlier ones) will fit as will the Mossberg, and a few others. Most on line gun supply stores will have them. Briley will have them for sure, but Briley tubes are usually on the expensive side. These other tubes will not have the knurled end sticking out as the Winchester has, but they will fit and work. You may also need a new wrench for them, but I always used a coin and it worked great.
