I have several hand guns and a few standard rifles. Never had a problem with any of them after I purchased them from a gun store. Well on Friday I purchased a semi auto Wasr AK-47. It was a used gun but every thing appeared fine it was 420 bucks. I went to shoot it today, loaded the magazine into the reciever and couldnt chamber a round. I attempted to hit the magazine catch to release the mag and nothign happened.. the 30 round mag is stuck in the gun and wont chamber a round. What recourse do I have if any ?? I am fuming right now that I just bought an expensive piece of wood and metal that wont even fire a round. Does the gun store have any obligation to accept the gun back or repair the gun once they sold it? Thanks for any help.
