I have thought about modifying my 10/22 too, but never got around to it. There are tons of things out there for them, barrels, stocks, triggers, muzzle breaks, hammers, you can basically rebuild the whole gun. I just really like the look of a big ol bull barrel on a short .22. Dont know how much they really improve the accuracy though. I read an interview with Mr. Ruger himself one time and he mentioned the 10/22 and said he never understood why people would change the barrels on his .22 that he built it with the best, most accurate barrels you could get. He said that he built one of the best .22's out there and doesnt think anything should be changed.
