Hey guys, I just bought a new Bushmaster and I was wondering if when I put in an empty magazine and pull the charger back is it normal for the handle to be pushed back into the receiver with no resistance? If I push the bolt release in the bolt and handle will slam home and lock up tight. It just seems like the handle is not connected to anything until you close the bolt(if that makes any sense). Please tell me if I have broken my rifle. Thanks, Shawn.
