I bought my first AR about 9 months ago and just now getting around to finally shooting it. I purchased a basic 16" barrel collapsable stocked Windham Weaponry. I have never owned an automatic rifle so this was a first. The first 3 groups of 3 shots apiece went into 1" at 100yards. with absolutely no load development. load was Varget and LC brass, fed. gold primer and 55gr. dogtown, to say the least I'm extremely pleased. these AR's are way more accurate than I had expected. Especially with the loose nut sitting at the back of the gun. oh yea optic is a Burris 2x-8x-32 older signature I purchased here also.
