It looks like the best thing for you would be a low-power variable scope in the 1X4 or 1.5X5 Magnification range. Some of the good ones are the IOR 1.1X4, Leupold CQT 1X3 Magnification, Leupold Mark 4 1.5X5 Magnification, Trijican Accupoint 1.5X4 Magnification, and the Horus Vision Talon 1X4 Magnification. The actual best scope in the class is the Schmidt and Bender 1.1X4 Short dot, but it costs $2000. The IOR is great and it comes with two reticle options, the regular CQB reticle and a new one that has the bullet drops on the reticle specifically designed for the 62 Grain bullet. The Leupold CQT is also good and they also have a new reticle similar to the IOR's new one. The Trijicon Accupoint is the least expensive and it has great reputation. A lot of people like it. Whichever one you get, it is best to get it with the Larue SPR type mount since some of these scopes have to be mounted far forward. However, if this is too high in your price range, then I would definitely recommend the IOR M2 scope which is a fixed 4X magnification scope. It is illuminated and it has the BDC Cam on the elevation turret for the 62 Grain bullets. It is a good scoe that you should ge able to get for about $350.00. But, your best bet is to go to a place that sells scopes and check them out and ask questions. You might also want to check out the "Complete Guide AR-15 book" But don't take anything you read from magazines too serious though.
