American Handgunner ran an article on a Ruger Mark 2 with a Volquartsen barrel conversion. They loved it, and it was a tack driver.

We've got seven Ruger in all. Aside from assembly issues, happy with them. I have used Volquartsen triggers on our Ruger 10/22 as that makes them easier for the boys when they were younger. All of our Ruger are incredibly accurate.
What a even more accurate rifle? CZ 455 Ultra Lux. That extra barrel length is big plus.
