I have one of those evil semiautomatic killing machines on order from Rock River and can't wait to play with it. Hopefully it will be done in a couple weeks with it being 6 weeks already come and gone since my order. I ordered the RRA ATH Carbine. I chose this one because its is a very sexy gun to me and I got an awesome deal through Legal Transfers LLC (saved over $250 using them). I will just be doing target shooting is all with it and maybe some small woodland creatures. I want this thing to be a tack driver shooting from a bench 100-300 yards out.I will be putting a bipod on it so now my decision comes down to a scope. I just don't know much about this stuff so I am wanting opinions. My buddy told me about the Nikon 223 scope such as the M-223 or P-223. Do any of have one of these and is it a good choice?
