I've just bought this 2nd-hand PC from a friend at Apknite and DayZ included. It means I'm a new player with not too much experience. I spawned in and the first thing I find is a cr 527 with a magazine in it. I find ammo for it and try to take the mag out to load it, but to my disappointment, the mag is glitched in the gun and won't come out. Can I do anything about this or am I just screwed at the moment.
