Hi, I posted this originally in the Gun show thread, because I bought this Kalashnikov style shotgun from at the Oaks gun show. But someone suggested it might be better to post here: I'm super new to shotguns and bought this one new from Bay Silah Firearms out of Hagerstown. I got it home and found some light rust on it, and that I can't get the dust cover open. The release seems to be fixed on to the dust cover itself, will not depress, and there is a bit of metal there that looks like it was welded. But admittedly I don't understand this well. I'd appreciate any advice on this. I've tried to contact the company and they're not responding, there was no owners manual.
