Does anyone have any experience with these firearms? I was thinking about picking one up to plink with. I don't know a whole lot about ar's and have posted on a couple of other forums. I am just trying to get as much info as I can before I shell out money for a gun. They seem like they have a lot going for them as far as what you get for the price. I thought I was pretty much settled on a Rock River but then I read about these and I am not sure now. Any advice or first hand experience would be great.
