Thanks for the recent article on the .300 AAC Blackout (.300 BLACKOUT: America's New Assault Rifle Caliber?, July 2013 S.W.A.T.). I had been looking to acquire a .30-caliber AR but could not decide which one would really meet my needs. Always looking for a reason (good or not) to build another AR, I've now built my own .30-caliber AR.
