The HS507C X2 gives you Multiple Reticle System (MRS) technology and extra-long battery life in a rugged reflex sight built for pistol applications. MRS technology provides the flexibility to change reticles with the push of a button. If you need a precise shot, run the 2 MOA dot only. When you need a reticle for fast target acquisition, turn on the 32 MOA circle with the push of a button. Or, combine both. The best part? There's no need to re-zero when switching reticles.
