Hope it works out for you. If it doesn't group as well as before, have it glass and pillar bedded. I've got a MkII .300 Win Mag all-weather I took out of the ugly paddle stock and put in a Boyds. It had to have the above changes (plus free floating the barrel) before it shot as good (now better) as before. If it's a calm day and I'm shooting good it's a one hole rifle.
Hope yours is too!
