The title says it all. I don't know jack about long guns. I've shot several rounds through an ar15 chambered in 223 and liked it. I'd like to buy or build a long gun of my own. Do you go ar platform, or ak platform? What caliber? I thought if i was just going to peruse various message boards for an answer, i'd start here. It would most likely be used for target shooting and things of that nature.
