Brownells sells the barreled actions, some are on sale low enough that you might be able to tweak it to your liking for a bit less than if you started with a complete one.Their walnut stocks are about $215, for instance.
I might dress up my 7.62 a bit when my grandson is through with it. DIP guard and release, maybe the Brownells stock. That wouldn't be the same as buying another rifle, right?
