It's a very versatile, rugged and compact design. Unlike a lot of scopes, it comes with its own mounting system and is ready to be mounted on either a rail or a traditional AR carrying handle. It includes a screw-in sunshade and flip-up dust covers, and the reticle has five brightness settings in both red and green depending on light conditions. Better yet, when the battery is dead or the power is off, you still have a black reticle.
Like I said, it's not optimum for precision long range stuff (the center reticle dot is 3 mils) but it does allow for pretty rapid target acquisition. The body of the sight itself has addition rails if you want to slap a small laser, flashlight or even a small 0X holo-sight on it.
FWIW, I'm very pleased with mine.
