The Holosun HS507COMP is a competition-bred open-reflex pistol dot with one mission: speed on the clock. Its oversized window gives a wide, distraction-free sight picture for fast draws and target transitions, and the red reticle delivers a crisp, instantly visible aiming point.
The headline feature is Holosun's Competition Reticle System (CRS): dial in a precise 2 MOA dot, or open up to 8, 20 or 32 MOA circles to suit the stage — switchable on the optic, no tools needed. Built on a 7075-T6 housing on the RMR footprint, with Shake Awake, Lock Mode and a side-loading CR1632 for up to 50,000 hours. In stock for fast UK dispatch.

Frequently Asked Questions
What do the CRS reticle options do?
A 2 MOA dot for precision, or 8/20/32 MOA circle-dots for fast, large-target acquisition — switchable on the optic to suit the stage.
What pistols does it fit?
It uses the RMR footprint, so it mounts to any slide cut or adapter plate machined for a Trijicon RMR.
How is the battery managed?
A side-loading CR1632 tray with Shake Awake and Lock Mode, giving up to 50,000 hours of runtime.
What is Lock Mode?
It disables the buttons so your settings can't be changed accidentally during a match or in the holster.
Is there a green or Ronin version?
Yes — the HE507COMP offers a green reticle, and the RONIN HS507COMP is the Ronin Tactics edition.
