HOLOSUN Elite Green Dot Sight  - HE508T-GR-X2

The Holosun HE508T-GR X2 Green Dot Sight provides a large field of view paired with useful features that will help you stay on target while greatly reducing target acquisition time. The X2 optics offer upgraded features such as a Lock Mode that prevents unintentional button presses while the optic is holstered and a side access battery tray, which allows the operator to change the battery while the optic is attached to the firearm. 

Holosun manufactured this product from light yet rugged titanium and added a multicoated lens that provides a bright, crisp sight picture. 

The Holosun HE508T-GR-X2 Green Dot Sight uses both Solar Failsafe technology and a high capacity lithium battery to power the optic, ensuring you'll always have a reliable point of aim in the field
