That model rifle has been discontinued for many years, due to the bolt and extraction issues. Bolt was machined from Tungsten which is 2x the weight of steel. If in great/excellent condition, you might be able to sell your rifle for $500 to someone needing an extra rifle for spare parts (less the bolt).
Sell yours "as - is" and by another brand in 22WMR. I know several rimfire shooters that have been looking for a 10/22M replacement bolt for over 10 yrs
