Stock is a McMillan A5, its now chamber in 30.06 As mentioned in the title 7mm mag. I would like to suppress it so besides the obvious bottom metal and mags what else will I need? Which bolt face(PTG Mag?), what twist barrel for the heavy pills, what length, what recoil lug, what trigger, what suppressor. Receiver is a square back. Add any other parts I may have missed(barrel nut).
