Mine seems to work with the browning chokes just fine. The threads are a exact match and length is correct compared to the factory NEF choke. The browning tubes don't extend past the end of the barrel though. I am not satisfied with the factory turkey choke pattern at all. But I just can't seem to get myself to spend over $100 for a choke tube on a $180.0o shotgun. That being said every turkey I've shot with my 10ga under 40yards has gone down like you've hit them in the head with a sledgehammer. I did get one at a lasered 48yards with the factory choke, I wouldn't have shot at that range except I miss judged the distance. I have heard the Rhino chokes are darn good.
