I have a new Condor O/U in 28" for waterfowl. Got a good deal, $299 at our local Dick's. Anyways, I have been preparing for the upcoming goose season by shooting some trap and noticed that after a few shots the fore end is becoming loose. It has even fallen off once during a round of trap! Yesterday I noticed that after a few shots the release lever seems to be opening up, if I squeeze the fore end to the barrel it tightens back up for the next few shots, but then I have to squeeze it tight again a few minutes later. I have taken it all apart and cleaned it very well. Everything seems to be fine including the release spring and latch on the barrel that the forearm attachs to. I am thinking that the when the barrel heats up after firing several rounds it is expanding an causing the forend to come loose. Any ideas of how to solve this??
