My good friend bought his daughter this gun in 20 ga ,to take to SD for pheasants, ,The night before they left, he dropped it off at my house and said it would not cycle, Keeps jamming, I read the post about the browning jamming ,and break free seemed to do the trick, Just wanting a comfirmation from you folks ,I have done everything else I know to do, ie clean, blow out ports and clean more. Could it be as simple as break free, to cure this problem,, Rem oil did not help....
