The 3xMag magnifying module (3xMag) is specially designed for compatibility with most red dot sights and for maximum flexibility and increased performance in the field. It is a revolutionary tool for military personnel, law enforcement, sport shooters and hunters. When combined with the FTS (Flip to Side) mount, the 3xMag magnifying module gives the user something never before possible - the ability to switch in a split second from CQB (Close Quarters Battle) to semi-sniping and vice versa. The versatile 3xMag also can be used as a handheld magnifying glass monocular for discrete observation and identification.

I ordered a magnifier and wanted it shipped overnight. Longhorn was amazing to deal with on the phone. Answered all my questions and I had my magnifier the next day! I would recommend them to anyone!
