Re: What's the difference between an AR-10 and an AR-15?

Exactly. And I would start with a 5.56 upper, and keep that as the standard rig, and simply buy/assemble a barreled upper in another caliber. You can swap out uppers in about 30 seconds. It's a lot easier doing that than it is trying to rebarrel a single upper whenever you want to switch.Carry-a-Kimber wrote:If you don't plan on running a suppressor on the rifle I would go with 6.8 SPC over 300 AAC for hunting.

Plus, if I get really brave, all I would need is the barrel and a barrel wrench (and some brave soul on the forum to hold my hand.)
