The Holosun 508T is a compact reflex sight engineered for slide mounting and duty use where weight and durability matter. The sight combines a multi-reticle offering with Holosun’s Super LED and solar-assist systems to extend operational life while maintaining a low mounting profile.

Optically the unit provides a 2 MOA dot, a 32 MOA circle, or a combined dot-and-circle selectable reticle set, with multiple brightness steps and Shake Awake motion activation. The housing is machined from titanium for a high strength-to-weight ratio and a subdued finish. Power is provided by a CR1632 cell with solar assist, electronics are sealed for weather resistance and the unit is compatible with RMR footprint plates and optic systems for direct mounting to compatible slides. No original box or accessories included.
