I got mine (Sturdy 5.56 mag) yesterday after about 320 hours played. I notice I'm running out of ammo way too quickly now. I need some better trigger discipline. Having 61 rounds in the mag made me lazy. I find myself tossing lead at the enemy even if I don't think I will hit them, because there's "plenty of ammo to spare" in the mag. But that's neither here nor there.
