Marky, my apologies for the late reply. I have no magnification on the rear sight, but the iris is adjustable and with 60+ year old eyes and bifocals; I am shooting good scores in the 4 position (prone, sitting, kneeling and standing) informal rimfire league at my local shooting range. Like you it is fun to shoot with scoped rifles but with the iron sighted rifles (FS 22lr and Trainer 17hmr) the shooting experience takes on a new dimension. As an added shooting enjoyment experience, at my local shooting range I participate in a .177 caliber air rifle league.
