What is THR's opinion on the Rock River Arms CAR A4? I am planning on purchasing my first AR in the near future and this is the rifle I am leaning towards. I want the A4 style as I would like the ability to easily and quickly mount optics on the rifle. This will be a plinker and defensive rifle. I have a Saiga now but have been bitten by the AR bug and now I would like to sell the Saiga and get an AR. So would this be a good rifle to purchase?Also what would be a good price for pay for such a rifle?
