I just acquired a 20 ga. express bbl. obviously some body didn't seat the rem choke and shot it and probably blew the end off, any way it does not have any choke at all. It was cut off at the next post area that supports the vent rib, only about three inches as it is 23 and 1/4 in long now. any recommendations on who could rethread it preferably back to rem chokes as that is what I have now and also my heirs down the road won't be as likely to screw it up again not thinking about it being different chokes.
I. D. is .616 O. D. is .765
