The worst thing that an owner can do with a .22 semi-auto is put oil in it. This acts as a magnet for dust and firing residue. The full tune on a Ruger 10/22 (2.5 lb crisp trigger pull, refit barrel, tune for subs, supply and fit buffer pin) should not cost any more than $60 from any competent gunsmith. It was a job I happily did for $50 and made good money as it takes about 30-40 minutes, and still under 1 hour if you include a threading job.
