I'm new with the semi's, and was wonderin which brand that yall prefer? Im looking to build a .308, maybe a DPMS or an Armalite, not sure which (any other suggestions would be great to). After the rifle, any suggested upgrades? I have a Zeiss off a previous bolt action build, just wondering what else would help. Like I said, first long semi-auto I've tried to build, not sure what all is different from the bolts. Thanks!
