I have to agree, you can find all of this on utube and do them yourself. I did. Free is a very good price.Those are all very simple modifications that can be done at home. That is the great part part about the 10/22. There are tons of online resources with pics and detailed instructions for all those things.
JBETT, Thank you very much for your reply. I will contact him.I have used the services of Burt Christopherson, 503-244-0305. He is very knowledgeable of most guns, new and old, fair in his prices, will turn down work that he thinks is not needed and even advise you of alternatives.
