They did during the 80's up until they quit making the late model 101's and 23's but they were a different thread pattern and diameter altogether. They were interchangeable with the original Browning invector and the flush mount Ruger chokes found on the Red Label and Gold Label. I would almost bet Briley has a thin wall flush mount in the original winchoke thread pattern & diameter.
Thanks Spank. I'll check it out
