The Holosun HE507COMP Green Dot Sight (HE507COMP-GR) is a 1x open-emitter competition pistol green dot sight on the Trijicon RMR footprint, with Holosun's Competition Reticle System — a 2 MOA green dot, or 8, 20 and 32 MOA circles — behind an oversized competition window. UPC 810047072911.
The oversized window all but disappears in front of the eye, so the dot finds the target rather than the shooter hunting for it through the glass, and the reticle can be sized to the stage: 2 MOA for a tight standard, 32 MOA when the targets are close and speed is everything. A green LED holds up better than red against bright outdoor backgrounds, which is why it is a common competition choice. 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 HS507COMP red and HS507COMP gold. For a single uncluttered aiming point in the same body, the HE407COMP green dot sight with the 6 MOA dot drops the circles. Step up to the HE507 ProMax green dot sight for a larger window, an integrated sunshade and Solar Failsafe, or see the titanium-hooded RONIN HE507COMP green dot sight.

Frequently Asked Questions
What is the Competition Reticle System on the Holosun HE507COMP?
The Competition Reticle System on the Holosun HE507COMP Green Dot Sight lets the shooter select a precise 2 MOA green dot, or open the reticle up to an 8, 20 or 32 MOA circle. Selection is done on the optic without tools, so the reticle can be matched to the stage.
Is the Holosun HE507COMP an RMR or an RMSc footprint optic?
The Holosun HE507COMP uses the Trijicon RMR footprint, so it mounts to RMR-cut slides and to optics-ready pistols supplied with an RMR-pattern adapter plate. It is a full-size competition optic rather than an RMSc slimline one.
Why choose a green reticle for competition?
The eye is more sensitive to green than to red at the same output, so the reticle on the Holosun HE507COMP tends to appear brighter and crisper against bright outdoor backgrounds. That is why green is a common choice for daylight competition shooting.
What is the difference between the HE507COMP and the HE407COMP?
The Holosun HE507COMP has the switchable Competition Reticle System with dot and circle options. The HE407COMP shares the same competition body and window but carries a single fixed 6 MOA green dot for the cleanest possible sight picture.
What battery does the Holosun HE507COMP use and how is it changed?
The Holosun HE507COMP 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.
How tough is the Holosun HE507COMP?
The Holosun HE507COMP has a 7075-T6 aluminium housing with a Hard Anodized black finish, is rated IP67 for water and dust, and is tested to 5000G of vibration.
