Volquartsen makes a VERY expensive 10/22 receiver...I've seen at least one other that was about the price of a new rifle. Somebody else makes a cheaper one, but iirc it needs some finishing to get it to drop into a stock.
You might want to check out Brownell's. But, by the time you pay the shipping and the transfer fee, it really is cheaper just to trot down to Wally World and snag one.

The superlite one for $196 actually looks pretty cool...it comes in colors, and has a built in scope mount. I could see buying that one...I've actually thought about it. As a matter of fact, I might just do that when I do my next 10/22 build. A nice shiny RED one
