The HS507K X2 is an open reflex optical sight designed for concealed carry pistols. The X2 Series pistol optics feature two improvements. 

1st = The addition of Lock Mode from our 2018-2019 LE pistol optic models. Lock Mode, when activated, locks the buttons preventing inadvertent setting changes

2nd = The buttons have been redesigned to compliment the Lock Mode by placing them lower and out of the way.


Additional features include: 

  • Holosun’s Super LED with up to 50k hours battery life
  • Multi-Reticle System
  • Shake Awake
