I have had a 10/22 since 1970, have done all the maintance on it myself. Rugers are easy to work on, most parts from Brownell's and reasonable. Mine is now due for the third set of replacement springs as the last were replaced in the mid 90's. I have an extra barrel if the original ever wears out. Have gone thru two stocks [broken in falls], three scopes [worn eye peace rings] and numerous bluing touchups. The bolt has imprinted on the face of the breach from so much use, still can hit what I cross hair with ease.
