The HE508T-RD X2 is a titanium, open reflex optical sight designed for pistol applications. The X2 Series pistol optics feature two improvements. First is the addition of Lock Mode from Holosun's 2018-2019 LE pistol optic models. Lock Mode, when activated, locks the buttons preventing inadvertent setting changes. Second, the buttons have been redesigned to compliment the Lock Mode by placing them lower and out of the way. Additional features include a Titanium housing, Holosun's Super LED with up to 50k hours battery life, Solar Failsafe, Multi-Reticle System, and Shake Awake.
