Man I thought this would sell out in a second so I quickly ordered it at its price... At the current sale price, this is by far the best magnifier possible. I wasn't sure on mounting options, but luckily this accepts any 30mm mount. I simply exchanged a cheapo 5x and put this on instead, and the edge clarity and eyebox is so much better. The height matches cowitness a flip to side mount I purchased on ebay for like 30 bucks, and because the aimpoint 3xc has adjustability to center the redot, the overall image is much better than what I had before. If this is on sale at the time you are reading this, I swear you cannot find any of these anywhere close to this price. Its very solid, and compact.
