My guess would be that the IO AR would be pretty much on par with the Radical Firearms stuff. Just a guess though. Now is definitely time to buy as prices have come way down due to demand, over supply, and the current political climate. I've seen rifles from Bushmaster, Del-ton, Ruger, and Palmetto State Armory for right around $500. While I'm not an AR snob, I am a sucker for things like chrome lined barrels, high pressure tested parts, and magnetic particle inspections so most of my "low end" stuff is from Spikes Tactical and Bravo Company.
