I have 10/22 that has about 2,000 rounds through it, two years old. All of the sudden the trigger would not reset. I can push the trigger forward and it will reset. I thought a good cleaning would do the trick. Took it back to range cycled perfectly for three or four 25 round magazines and it started the same thing I was able to push the trigger forward and it would fire that one shot. I have repeated the cleaning shooting process two two more times with the same result two or three magazines perfect and then trigger won't completely reset. Any suggestions.
