I shot the 3-12x42 in the BDC reticle at a range in the states that was only 200 yards. Very fast acquisition of target and very easy to use. I had never shot an AR before and quite enjoyed it. The big sell point is the custom mounts that are provided with it. They are designed to sit properly with a good eye relief on an AR. CGN doesn't appreciate me putting up promo pieces without being an official sponsor, but if you want check out the nikonhunting.com site and watch the promo video. Its around five minutes and will give you an overview of the two reticles and the point blank. The guy you hear introducing everything, not the narrator, is John Lacorte and he is the designer of our BDC reticle. (Purple safety glasses).
Unfortunately with us currently not listing in Canada I can't give you a price point as thats above my pay grade but if you can play with one down south give them a shot. Lots of fun.
Be a great varmint hunter.
