I suppose this has been covered a gazillion times - but who makes the best threaded barrel for a Ruger 10/22. I have a sparrow suppressor which I use on my S&W 41 - and would also use it on the Ruger, although I think I would also consider an integrally suppressed barrel, just so that the the Ruger is always ready to go suppressed. Any feelings about the integrally suppressed barrels - especially accuracy and durability? Thanks
