Eye relief refers to the distance between your eye and the lens at the rear of the scope that will give you a full crisp view, no dark ring around the edges. Important to know for high recoil calibers to avoid a black eye or worse. Some scopes are single power (3Ã32, 4Ã30 for example) which means no adjustments.
BDC Rifle Scopes. BDC is an acronym for bullet drop compensation and refers to a setting on the scope where you can adjust the range to factor in bullet drop. In most cases BDC is caliber and even bullet weight specific. There are a number of rifle makers in the market who offer a BDC model, but my 2 favorites are BSA and Nikon.
