The 508T X2 is a hard-use open reflex sight designed for handgun applications. Features include a grade 5 titanium housing with industry standard footprint, Holosun’s ultra efficient 540nm Super LED with up to 50k hour battery life from a 1632 battery, and a Multi-Reticle System providing 2MOA dot only, 32MOA Circle only, or Circle-Dot combination.
 508T X2 also features Solar Failsafe and Shake Awake technology, and Lock Mode which, when activated, can prevent inadvertent setting changes. 508T-X2 features 12 intensity settings, two of which are compatible with night vision devices.
Granite Ridge's Take
The Holosun 508T X2 combines an open-reflex layout with a titanium housing for shooters who want a durable optic without moving to an enclosed-emitter design. It sits near the top of Holosun’s traditional open pistol-optic lineup and is a natural comparison point against the 507C X3 and 509T X2.
Buying & Compatibility Notes
Compare with 507C X3 for value and 509T X2 for enclosed-emitter protection. Confirm slide or plate compatibility with the RMR footprint
