My wife and I both have the Aim Point Pro on our KAC SR 15 rifles with a primary arms 3 magnifier. This site is really really good! Easy to zero keeps the zero and is rock solid. the red dot is clear and adjustable for different lighting conditions the battery lasts about three years its always on and ready to go if TSHTF. I like everything about this optic, from the price to the looks of it. I would recommend it to anyone.
