Ive got a buddy looking for a scope for his 6mm Rem in Ruger 77 and Ive got a stock that came off a ruger 77 220 Swift,do these two rifles interchange on the stocks...............

Well if they are both tang safety or both mark II's and if the barrel profile is the same then the answer is yes.
If answwer is no to any one of the above questions then the answer is no.

alrighty then Iguess the answere is yes,thanks again...............
