Thanks Mudhen, I measured the one they sent me and it is 1 1/2 inch. I emailed Rhino to see if they knew of any problems but haven't heard back from them yet. The problem appears to be that it is making contact the first place it flares on the bottom of the tube. I'll get it corrected, did take a gobbler at 35 yards with the SBE II and Comp-n-Choke combo on Tuesday. Thanks for the help.
I got the Rhino choke tube that's suppose to fit the SBE II and Beretta Xtrema and it wouldn't fit my gun. I have a Comp-n-Choke, unscrewed it and the Rhino wouldn't make it into the barrel where the threads start. Anybody else have this problem? Choke came from Wing Supply and is the 2" extended version. I have been in touch and they will exchange it but I want one that will fit.
