Guys is there any legal problems with taking a factory ruger 10/22 barrel and cutting of .200 " on the chamber end and recutting a new chamber. The shoulder would need to be set back the same distance. This would make the 18.5" barrel 18.3". There is a lot of guys using these reworked barrels in the States and claim good accuracy. I would like to try this seeing that I have a spare factory barrel kicking around.
