So, my father's 10/22 just recently started acting up. He's only had it for a few months and put only 100 rounds through it and all of the sudden, he could no longer lock the bolt open.
So I disassembled it this afternoon. I assumed the problem was in the trigger group even though everything appeared to be fine. I disassembled it and reassembled it. Upon reinstalling the trigger group back into the receiver, I discovered the real problem. I found the large pin at the rear of the receiver lodged in there crooked and it was preventing the bolt from reaching full travel.
Upon further inspection, it appears that the pin is somehow way too short. The receiver measures 1.256" wide, while the pin is only 1.011" long. When the pin is flush on one side of the receiver, below is how it looks/fits.
What's going on here?
