The EOTech G43 is a 3X fixed magnifier that mounts behind an EOTech holographic sight to extend your effective range. It ships with the Switch-to-Side (STS) mount, so you can swing the magnifier off-axis and go back to 1X without tools when targets get close.
The G43 is EOTech's compact 3X magnifier. It gives 2.50" of eye relief and roughly a 7.5° field of view, and the adjustable diopter lets you focus the image for your eyes. An anti-fog coating keeps the glass usable through temperature changes. Behind a holographic sight, you get a magnified view of the same reticle for longer shots, then flip the magnifier aside for close-range work.
Mounts on any Picatinny rail with the included STS mount. Place it directly behind your holographic sight, set the diopter, then confirm the magnifier swings clear of the sight and locks in both positions.
