hey y'all I've posted this on another forum as well but i love my DD rifle is 5.56 but recently found the 6mm creedmoor and bought a ruger precision rifle in that caliber but still considering the caliber in a AR platform so was thinking of buying a DD rifle and switching it from .308 to the 6mm just curious if anyone could help me with what all i would have to change or is it even possible to switch?
