Overview
The Eotech 3x30.5mm x 21.6mm Holographic Hybrid Green Dot Sight is a robust optic designed for precision aiming with its green reticle. It features a holographic design that allows for quick target acquisition, and it mounts securely to a Picatinny rail, making it compatible with a variety of firearms. This sight is frequently found on builds utilizing a mid-length gas system chambered in 5.56 NATO, providing the ideal balance of performance and versatility.

EOTech holographic hybrid green dot sight returns to zero perfectly after detach and reinstall. Glass is sharp at typical engagement distances. Battery life on hybrid mode is significantly longer than my old XPS. Solid premium optic.
