The Aimpoint(R) 3XMag-1 can be used in conjunction with all Aimpoint(R) sights for long-range aiming or observation. A variable (-3 to +3) dioptric setting allows this magnifier to be adapted to the individual operator's eye. The 3XMag-1 can also be used as a handheld 3X monocular. Aimpoint magnifiers utilize the red dot in Aimpoint sights as the aiming reticle,eliminating the need for re-zeroing when shifting between non-magnified and magnified aiming. The 3XMag-1 is encased in a shock absorbing protective rubber cover that also creates an ideal ergonomic grip. Internal optical adjustments make aligning the magnifier and sight quick and easy.
