I have a new, 12 gauge H&R Topper with a factory screw in choke tube. Anybody know if another brand of choke tubes are interchangable? Thanks.

They are compatible with Winchokes.

A pretty good reference resource at this link:

They will also work with Mossberg Accu choke tubes, older Browning choke tubes, and Colonial choke tubes cut and threaded for those models.

Thanks. I had determined that Remington chokes from my 870 DON't work :)

Y'all made life a bit easier. Thanks again!! :D
