When did Ruger stop putting walnut stocks on standard 10/22 carbines? (Not including deluxe sporters, just standard carbines).
Wasn't the last year of the 1022 carbine walnut stocks 1977.According to Workman's book, 1981 was "officially" when the Walnut stock material was dropped. There was an overlap of the Walnut and Birch stocks during a transition period. Lowest Birch "recorded" was 119-70067 and highest Walnut was 121-50355.
I have seen lower numbered serials with a Birch stock, I just don't know if they were swapped out for Walnut by previous owner/s or not.
