Lately I've been getting the itch to pick up an AR pistol just for giggles. What's the best bank for the buck out there? I've been out of the AR platform game for a while. It used to be stick to ABC (Armalite, Colt, Bushmaster) and you were good. That's probably not the case any more. I've been reading a bunch on AR15.com but most of those guys roll their own.
2nd question. Is 300 blackout worth the extra up front and ammo cost?
