This scope comes with an American Defense quick release picatinny rail mount. The mount allows you to remove the scope and put it on without losing its sight. The scope is a true 1:1 so you cna use both eyes open and see through the scope and see your suroundings with the other eye. It magnifies to x4. It has a lighted reticle with 100, 200, 300, and 500 yard marks for a 5.56mm round. The lighted reticle has multiple brightness levels and each one is separated by an off position on the rotating knob. It is a bad a_ _ scope. New the scope cost 1000 and the mount about 150. It comes with the original box and paperwork and is about one year old. Thanks, Michael
