So I was able to snag another Mega lower and am trying to decide what to build. I already have a Mega.223 and a Mega.308. I've been flirting with the idea or a 300BLK or a 6.5grendel, but maybe I should just build another .223. Any opinions? I'm not in a huge hurry because I'm sure things will settle down (at least uppers/bolt carriers/ammo will settle down)
