I bought my 10/22 back in the mid 80's. It has had thousands of rounds through it. Never had any trouble with it. Still shoots like it did when I was shooting it as a teenager. Has anybody ever wore one out? Sometimes I think I should buy a new one as a spare, but it has never given me any reason to doubt it. Just a thought.
Ive got one from 2002 and have shot thousands of rounds through it and actually have never cleaned it yet it just keeps shooting....even shot a couple competitions with it back in the day, still going with absolutely no issues!
They should last a lifetime. I have 23 of them with the oldest being from 1965. This was the 2nd year of production.
