I use the same Choke tubes in my T/C 12ga as I use in my S&W, and Mossberg 12ga. I do believe they are Browning tubes. I'll have to check.
Let me take the above back. Can't remember which tubes I use in my T/C 12 ga. It's buried under about 30 guns and barrels and I don't feel like digging it out at this time. I do know when I bought it I found I already had choke tubes that fit it. And after thinking about it for a while I do believe the choke tubes came from my Stouger 12ga Skeet gun. But I still think the little plastic tubes the choke tubes came in say Browning on the outside.
Best thing to do is take the tube currently in the barrel with you to the gun store, and match it. In most cases when the guy behind the counter sees it he will know which one you need.
