The American Defense Flik fixed power magnifier is an extremely short, high-performance optic that will increase the capability and accuracy of any red dot or holographic sight. The patent pending, ambidextrous mount allows the shooter to quickly transition from 1x to 3x/5x by simply flipping the magnifier back and fourth from the line of sight. The mount interface provides two positions to mount the optic that offers additional eye relief options to accommodate various cheek-weld positions on the stock. In addition, the FLIK comes with both a 4mm and 8mm spacer that adapts to most red dot sights to provide, low, co-witness, or lower 1/3 co-witness alignment.
