The Primary Arms Basic Flip to Side Magnifier Mount with thumb screw mount is perfect for placing a magnifier behind all standard height 30mm red dots, Micro dots, and reflex sights using a lower 1/3rd cowitness height. Once your magnifier is installed in the 30mm ring, simply pulling the magnifier to the rear unlocks the mount, allowing you to instantly choose between centerline and off-centerline positions. This tough mount features a lifetime warranty.
NOTE:This mount places the center of the magnifier 1.64 inches above the top of the 1913 Picatinny rail. The magnifier will NOT line up with raised base optics such as the 7mm extended base EOTechs!
