This scope is amazing! it adjusts really easily and is really helpfull.a cool feture that no1 mentioned was that the lens covers can come off. if you look at the picture you will see that the lens covers are connected to the scope but the peice its connected to on the scope is rubber and can slide off the entire ring and you can play with out the lens covers wich is a good idea because my freind played with his on and they got shot at and they broke and cracked. this scope has red and green dots and 5 diffrent levels of brightness which is awesome. with out the lens covers the scope loks slimmer and even more awesome.oh yeah by the way i bought this for my JG M4 S SYSTEM NHANCED VERSION and it fits great looks great and YOU DONT NEED A RAIL MOUNT. there was only 1 thing that i was,well i wouldnt say dissapointed but surprised that the front lens onmine was chrome/silver where in the picture its red.the pros and cons are:
-Lens covers easily removable(they slide right off)
-2 colors of dots
-comes with 2 batterys(though 1 of them lasts FOREVER!)
-Also comes with a cleaning cloth that you can also use to clean your gun with.
-honestly NONE! this reflex sight is amazing and very durable i would recommend this scope to anyone
