Ooh, hey, can I play?
That's me slinging up Sting, my 1981 vintage 10/22. Garand sling, modified bolt release and hammer, Bell & Carlson extended mag release, nylon bolt buffer (made out of a nylon bolt

), Volquartsen extractor, and a Weaver K7 scope (I just can't really see the 4 MOA targets real well otherwise!).
This is my beater that I just put together a few months back; it's purely a loaner.
Here's what I did to it:
Added Tech-Sights. ($55)
Replaced sear spring (free from Ruger as original had broken)
Stoned hammer
Stoned sear (since the new spring was pushing the sear down to far to allow the safety to engage)
Hogged out the bolt release so it's a one hand operation to release the bolt
Stoned down the bolt (it had gotten somewhat rusted)
CLEANED it (it was NASTY)
Installed Volquartsen extractor ($12)
Installed Bell & Carlson extended mag release ($5)
Installed sling, studs and swivels ($18)
removed barrel band (not needed)
polyurethaned stock (the finish had worn off - it was UGLY)
Added 3 more magazines. ($39)
The dealer I got it from had wirebrushed the barrel (I think) because of rust on the underside where the barrel rests in the stock and sanded down the stock (again, I think). I knew what I was getting when I bought it. It was all of $110. Accessories were about $133. Hasn't made any riflemen - yet - but it will. It shoots pretty good for a beater.
BTW, I'm an Instructor up in New England.
