Holosun 508T X2

The Holosun 508T X2 is a hard-use open-emitter pistol optic available with either a red or green Multi-Reticle System. Select the preferred reticle color from the available options above. Both versions combine a Grade 5 titanium housing, RMR footprint, Solar Failsafe, Shake Awake, and a selectable reticle system designed for duty pistols, defensive carry, competition, and high-round-count training.

Holosun’s Multi-Reticle System allows the shooter to choose between a precise 2 MOA dot, a fast-acquisition 32 MOA circle, or the combined circle-dot reticle. The dot provides a refined aiming point for deliberate shots, while the larger circle can help guide the eye during rapid presentations and close-range target transitions.

The Red model uses a 650nm Super LED, while the Green model uses a high-visibility 540nm Super LED. Both reticle choices provide up to 50,000 hours of battery life at setting six and offer eight daylight and four night-vision-compatible brightness settings.

Solar Failsafe supplements the CR1632 battery with available ambient light and supports automatic brightness adjustment as lighting conditions change. Manual Mode provides direct control over reticle intensity, while Shake Awake places the optic into standby during inactivity and immediately restores the previous setting when movement is detected.

The side-loading battery tray allows the CR1632 battery to be replaced without removing the optic from the slide or disturbing its zero. Lockout Mode helps prevent accidental brightness or reticle changes after the preferred settings have been selected.

A precision-machined Grade 5 titanium housing gives the 508T X2 exceptional impact resistance while keeping the optic to approximately 2 ounces. Its squared protective structure provides added reinforcement around the lens without creating excessive bulk on a reciprocating pistol slide.

The Holosun 508T X2 uses the widely adopted RMR footprint for installation on compatible optics-ready pistols, direct-milled slides, and adapter plates. IP67 environmental protection and a 5,000G vibration rating prepare it for exposure to water, debris, recoil, and demanding field conditions.
