without a doubt that ar will take you out to 600 if you know how to get there. a good scope will really help imo so dont hesitate to go out and get a leupold or something equal. ballistic charts help to but are almost nothing without a good personal weather device. if you already have a scope on it, try just gettign out to 500 yards and keeping the gun sighted for that range and start practicing. if you can hold a group your good to go out and get better optics and all the fancy toys to go with it.
