Why use this optic - If you are new to carbines, the Holosun 510C is the best entry level reflex optic to get before moving onto something more premium for the MCX.

3 Reticle Patterns - Cycle between 3 reticles based on your tactical needs

  • 65 MOA Ring Only
  • 2 MOA Dot Only

Large Lens For Faster Shooting – Parallax-free reticle with unlimited eye relief with this large POV to instantly place the dot on the target while shooting on the move or transitioning with both eyes open

Never Turns Off - The Solar failsafe technology extends the battery life longer on top of the existing 100,000 hr battery life to keep you in the fight longer without ever changing the battery

Mount on any M1913 Rail – Quick detach lever mount for fast on/off MCX's top rail, and also use it on other guns in your collection
