I have a rock river arms AR, that I am torn over. This rifle is fun to shoot and I've only owned it for about 7 months. Winter is upon us and I'm out of ammo (minus the one magazine that is for just in case). Anyways, I've been toying with the idea of just simply selling it. Or...
buying a different upper to have a multipurpose AR.
Anyone here use same lower and just swap out uppers?
If so, what are advantages if say: .308, 6.5, so com caliber?
My second purpose would be for hunting. Iron site gun.
