Just got a new stock for precision savage build but it has no mag port looks like a blind mag. Can these be altered to fit my current model 10 its a vlp .243/w dbm? or will a new savage have to be perchased .Action screws are at 4.4 o/c,on the choate tac. stock. I did not know model 10's came without a detachable mag. what model 10 action would be appropriate for this blind mag choate tac.
