Hey guys. I was just shooting my mk2 in the backyard with my donny ronin and when I unscrewed the donny the whole barrel unscrewed. I removed the shroud and started threading the barrel back in the reciever. It starts threading in but the barrel is still a good centimeter away from the breech and the oring popped out when i was lightly pushing the barrel. I know the barrel must thread in to that oring area directly and somehow its off center but how exactly am i supposed to guide this in correctly? I hope I didn't break anything.
