My L2 has sat unused (I know I know
) for about a month and when I picked it up yesterday I noticed that it only shot once after locking the rear into place. Open the action and close it again for the next shot. No more semi-auto. I tried both with & without pellets. The only thing I did recently was swap out the moderator to the largest Valkerie can. I don't recall adjusting anything else. I haven't tried to revert moderators yet either.
Quick fix?
