Well the range i am going to take my AR for the first time requires to have it "bore sighted". What is the easiest way to do that at home, or is there a way? Take into account i live in town, so me sitting in my back yard is OK just as long as the neighbors don't call the locals!!! I know this is more of a newbie thing but i have never really had a AR with a scope on it so the last time i sighted in a scope was about 3 years ago on my muzzle-loader!!! Thanks and sorry for showing my greenery with optics, oh its a Trijicon 1.5 x4.
