I have one of the first Ruger M77 MarkII Target rifles in 308 Win. It actually has a blued receiver and a stainless heavy barrel. I've got 2 other 308s I shoot and this gun has just been collecting dust. I'm kinda interested in the Gunsite Scout rifle with a DBM, scout rail, open sites, and 16in barrel. Would this be a simple stock change with the required bottom metal? I believe the scout rail mounts off the front scope ring mount. The only permanent modification would be hacking off the barrel and installing a front site.
