My saiga is only shooting every other round. I'll fire a shot, the empty shell ejects, a new shell gets loaded in the chamber, and then when I pull the trigger... nothing. It's as if when the bolt carrier slides back... it's ejecting the shell just fine but not resetting the trigger. When I pull the trigger it's just loose and I can keep rapid pulling it and nothing is gonna happen.
So here's the sequence of events. I shoot the first shot, the bolt flys back ejecting the shell, the bolt flies forward and loads a new cartridge, I pull the trigger, nothing happens, I then manually pull back
