Great value - Primary Arms Classic Series 21mm Micro Reflex Sight with Autolive, 3 MOA Red Dot

I purchased this to use on my moms Equalizer and so far, it has performed well with 100+ rounds through it at the range. The glass is clear and the dot is bright enough for her to see and shoot well. My only complaint is the need for a tiny allen key to make the elevation and windage adjustments, which they provide. But if you don't have the tool on you, you're S.O.L. Budget optics are often overlooked by the "big" GunTubers as they frequently recommend flashy big name things most people just can't afford. You don't need to 4-7 bills on a quality optic, especially if you're not jumping out of helicopters in a warzone.
