The Holosun HS507COMP Red Dot Sight (HS507COMP) is a 1x open-reflex competition pistol red dot sight on the Trijicon RMR footprint, with Holosun's Competition Reticle System — a 2 MOA red dot, or 8, 20 and 32 MOA circles — behind an oversized competition window. UPC 810047072928.
The window is the reason people buy this optic. It is deliberately larger than a standard 507, so the housing gets out of the way on a fast draw and on transitions between targets, and the reticle can be sized to the stage rather than the other way round: a 2 MOA dot for a tight standard, or a 32 MOA circle when the targets are close and the clock is the only thing that matters. Switching is done on the optic without tools. The 7075-T6 aluminium housing is finished in Hard Anodized black, rated IP67 and tested to 5000G, with Shake Awake, Lock Mode and a side-loading CR1632 rated to 50,000 hours.
How It Compares
The same optic is available in HE507COMP green and HS507COMP gold. For a single uncluttered aiming point in the same body, the HS407COMP red dot sight with the 6 MOA dot drops the circles. Step up to the HS507 ProMax red dot sight for a larger window, an integrated sunshade and Solar Failsafe. The titanium-hooded RONIN HS507COMP red dot sight is the enclosed-style RONIN finish of the same reticle set. Browse all RMR footprint red dot sights and the wider Holosun pistol red dot sight range.

Frequently Asked Questions
What is the Competition Reticle System on the Holosun HS507COMP?
The Competition Reticle System on the Holosun HS507COMP Red Dot Sight lets the shooter select a precise 2 MOA red dot, or open the reticle up to an 8, 20 or 32 MOA circle. The selection is made on the optic without tools, so the reticle can be matched to the stage rather than fixed at purchase.
Is the Holosun HS507COMP an RMR or an RMSc footprint optic?
The Holosun HS507COMP uses the Trijicon RMR footprint. It mounts to any slide cut for an RMR and to optics-ready pistols supplied with an RMR-pattern adapter plate. It is a full-size optic and is not intended for RMSc-cut slimline slides.
What is the difference between the HS507COMP and the HS407COMP?
The Holosun HS507COMP has the switchable Competition Reticle System with dot and circle options. The HS407COMP shares the same competition body and window but has a single fixed 6 MOA dot, which keeps the sight picture as clean as possible.
How is the HS507COMP different from the HS507 ProMax?
The Holosun HS507 ProMax adds Solar Failsafe supplemental power, a larger window with a forward-leaning integrated sunshade and a runtime rating of up to 100,000 hours. The HS507COMP is the simpler competition optic, without solar, rated to 50,000 hours.
What battery does the Holosun HS507COMP use and how is it changed?
The Holosun HS507COMP uses one CR1632 cell in a side-loading tray, so the cell can be replaced with the optic still mounted and zeroed. Shake Awake supports the 50,000-hour runtime rating.
What is Lock Mode on the Holosun HS507COMP?
Lock Mode disables the buttons on the Holosun HS507COMP once the brightness and reticle are set, so a stage setting cannot be knocked out of position between strings or in a range bag.
