    EO Tech EXPS2-2

    I began looking for an EXPS2-0 after seeing one at a local gun show. As I do with everything weapon related I researched the internet for current pricing and of course, "a great deal." After several days of research I found AT3's website and read about their sale of opened box/returned items. AT3 had an EXPS2-2 listed, and at a price that couldn't be beat! Plus they gave an additional 10% off and free shipping too! Item operates as designed and mounted beautifully. I have not had a chance to take it to the range yet. Looking through the site at two (2) 1 MOA dots will take some getting used to I suppose. I can't say yet whether this sight is the equivalent of having a third eye in the middle of my forehead. But I will say this about AT3; they have great products, competitive pricing, fast shipping, etc., etc., etc. Thanks AT3
