The Aimpoint 3X Mag-1 Magnifier can be used in combination with all Aimpoint sights to give the shooter and extended range for both aiming and observation. When using an Aimpoint 3X Mag-1 with a red dot sight, the red dot is used as the reticle. This removes the need to re-zero when changing from zoomed and non-zoomed aiming. In addition to being an optics magnifier, the Aimpoint 3x Mag-1 can be used as a handheld monocular. This function is enhanced by the shock absorbing, protective rubber coating which provides an ergonomic grip. Aimpoint 3X Mag-1 Magnifier (No Mount)
