Okay, so i purchased a used WASR in 5.45 off of here a while back, and the first time i go to shoot it, i rack the slide back, and it wont go all the way forward.. the bolt is trying to strip the round, but is coming into contact about half way up the round.... now, if you hold the rifle by holding the magazine and pulling it towards you, the rifle will feed rounds reliably and otherwise fires like a champ... so, should i just attempt to clamp down the magazine well a bit?
