Lucid LLC 2X Magnifier 2Oz Threaded For HD7 & M7 Red Dot Black Magnification L-2X

This is a great screw on magnifier for my M7 mini dot sight. It screws on off quickly and easily, and Wholesale Hunter is selling them cheaper than anyone else out there! ( I checked amazon, Ebay, and several local retail stores)

Does exactly what it is supposed to. Threads on with no wobble or rattle. I am not sure how much it actually magnifies, but it does create a kind of fish eye view. The dot was blurry for me, which is why I got it. Works great for bringing the dot into focus. It narrows the view significantly. Also makes two eyes open shooting difficult. I like it and would recommend if you have an HD7 and don't want a flip to the side magnifier.
