I have a like new Top single barrel for a Browning Citori . It`s from a early model 1980`s, ser# 156xx . Fit on one at the club but doesn`t fit my Grade 6 without some work - close !! I have a bottom release so it does me no good . 34"Full fixed choke , ported and bluing as new !!! Used some so it has a few match up marks to the receiver and forend but slight . $1200 plus shipping from NJ .
