I have red-dots, shotgun, fixed, variable, run from Ziess to Nikon, Sightron II, Simmons, (new+old), Weaver, (new+old), Brunton,Bushnell, Barska and a couple of others I can't remember. To be honest, The Ziess is great, but not worth the multiple price from the new Simmons or new Weavers. Nikons and Sightron are also very good. Friend of mine has a Burris and has offered to trade me straight up for a Simmons Pro-Hunter! His was 3X the price of mine! I like good glass, but it pains me greatly to pay as much for glass as the damn rifle. Really am satisfied with the new Simmons line and the new Weavers. Both are made by Meade I believe. All but the Barskas give good enough vision to see to shoot till the end of legal hunting time, don't really need much else. DP.
