The Holosun HS407COMP Red Dot Sight (HS407COMP-RD-6) is a 1x open-emitter competition pistol red dot sight on the Trijicon RMR footprint, with a single fixed 6 MOA red dot behind a large competition window.
It is the clean-sight-picture option in the COMP range. Where the 507COMP gives you switchable circles, this one gives you nothing to think about: a bold 6 MOA dot that the eye finds instantly on the draw, in a window big enough that the housing stops being part of the sight picture. The 7075-T6 aluminium housing is rated IP67 and tested to 5000G, with Shake Awake and last-setting recall, and a side-loading CR1632 rated to 50,000 hours.
How It Compares
For a switchable dot-and-circle reticle in the same body, the HS507COMP red dot sight adds the Competition Reticle System. The same 6 MOA dot is available in HE407COMP green and HS407COMP gold. For Solar Failsafe and a larger window with an integrated sunshade, see the HS507 ProMax red dot sight. Browse all RMR footprint red dot sights and the wider Holosun pistol red dot sight range.

Frequently Asked Questions
Why does the Holosun HS407COMP use a 6 MOA dot?
A 6 MOA dot is large enough for the eye to find immediately as the pistol comes up, which is what matters on a close-range competition stage. The Holosun HS407COMP Red Dot Sight pairs that bold dot with a large window so there is nothing else in the sight picture to slow the shooter down.
Is the Holosun HS407COMP an RMR or an RMSc footprint optic?
The Holosun HS407COMP uses the Trijicon RMR footprint, so it fits RMR-cut full-size pistol slides and optics-ready pistols supplied with an RMR-pattern adapter plate. It is not an RMSc slimline optic.
What is the difference between the HS407COMP and the HS507COMP?
The Holosun HS407COMP has a single fixed 6 MOA dot. The HS507COMP adds the switchable Competition Reticle System, which offers a 2 MOA dot or 8, 20 and 32 MOA circles selected on the optic. Both share the competition body, RMR footprint and CR1632 battery.
Does the Holosun HS407COMP have Shake Awake?
Yes. Shake Awake on the Holosun HS407COMP switches the dot off when the pistol has been still and restores it instantly on movement, with last-setting recall so the brightness returns to where it was left. That is what supports the 50,000-hour runtime rating.
What battery does the Holosun HS407COMP use and how is it changed?
The Holosun HS407COMP uses one CR1632 cell in a side-loading tray, so the cell can be replaced with the optic still mounted and zeroed.
How tough is the Holosun HS407COMP?
The Holosun HS407COMP has a 7075-T6 aluminium housing, is rated IP67 for water and dust, and is tested to 5000G of vibration.
