Ok gang, I need your expertise. I've never had a Mac90 before. I just bought a Norinco Mac90 today, and I'm not sure what the deal is with the mechanism that locks the bolt back. I can rack the bolt all the way back and all the way forward multiple times, and I can also slide the bolt about 1/2 way back at which point it will sometimes lock open in this position. In order to get it to release, I just barely tap the bolt handle and it will spring forward which is just what the guy I bought it from did. My question is:
Is there something wrong with the gun? It just seems odd to me that there isn't some more definite way to lock the bolt back, and it also seems odd that simply tapping the bolt handle will release the bolt to spring forward. I'm not quite sure what the internal mechanism is that actually holds the bolt back once you lock it open, but if simply barely tapping it will cause it to spring forward in the closed position, it seems like something must be broken or not working right in the gun? Or is this normal? The gun appears to be in almost new condition with a wood thumbhole stock and a rubber recoil pad, and the guy I bought it from says he only ran about 1 or 2 magazines of ammo through it. Help. Thanks.
