RUger may do it for you for free, but if you have an action job or non stock ruger parts, they will replace them with ruger parts when you get it back. there CS is good, they will even go so far as destorying the gun, then replacing it with the exact serial number.( so no back ground check and other bs per state law) personally i'd check youtube, you may just find it. lots of good ( and bad) stuff on there.
