Its very low profiled so if you use it on an AR, be sure to get a riser so you dont mess your neck up. Also it doesnt have an off button, it shuts off based on darkness. All in all, its a great small profile redot that wont clutter up your rail of add much weight.
Pros: Price, features, profile
Cons: no off button
