Hello my fellow Benelli Owners! i just purchased my first Benelli, it's a supernova, but it's used. i have a couple questions? Since I purchased it used I don't know but it seems like the charging handle/forend is loose and wobbly. Is there any way to make it smoother? my second question is where can I get a 22-24" barrel? It doesn't need to be factory Benelli, but I would like it to have a raised rib front sight since I have a peep hole rear. from reading on this forum it seems like Nordic is the way to go for mag tube extensions so I'm set there. I'll post some pics and tell me what u suggest. Thanks for ur time... sffred
