Unity FAST Magnifier Mount they use 2 powerful magnetsThe Unity Tactical FAST OMNI Magnifier Mount is designed to accommodate the most popular magnifiers that need to sit at a taller height then standard mounts can achieve. It utilizes Unity Tacticals unique Flip To Center mechanism that allows you to stow the magnifier over the receiver instead of off to the side like traditional mounts. This reduces the possibility of the optic snagging on any gear or environmental hazards. Features: Made from 7075 T6
