Details
Description
Holosun RONIN HE507COMP Green Dot Sight wears Holosun's premium Ronin build and finish on the competition open reflex, and drives the reticle with a green Super LED. Behind the large 1.1 × 0.87 in window sits the Competition Reticle System: a 2 MOA green dot on its own, or wrapped in an 8, 20 or 32 MOA circle depending on how much of the target you want the reticle to cover.
How It Compares
The same optic in the standard finish is the HE507COMP. For the red emitter in Ronin trim, go to the RONIN HS507COMP Red. There is more to weigh up across our competition red dot sights and green optics.
Ideal For
- Practical and action pistol stages
- Shooters who pick a green dot up faster

Product FAQs
How does the RONIN HE507COMP differ from a standard HE507COMP?
Ronin is Holosun's premium series, so the RONIN HE507COMP has an upgraded build and finish over the standard model. The reticle and optical package underneath are the same.
Which circle should I run on the RONIN HE507COMP?
On the Holosun RONIN HE507COMP the 32 MOA circle is the quickest to find, the 8 MOA keeps the picture tight, and 20 MOA sits between them. You can also drop the circle entirely and shoot the 2 MOA green dot alone.
Do I have to remove the RONIN HE507COMP to change the battery?
No, the CR1632 in the Holosun RONIN HE507COMP loads from the side, so the optic stays on the slide. Battery life is rated up to 50,000 hours.
Should I choose the RONIN 507COMP in green or red?
Mechanically the green and red versions are the same sight, with only the emitter differing. Some shooters simply find the green of the RONIN HE507COMP quicker to pick up.
What reticle options does the RONIN HE507COMP have?
The Holosun RONIN HE507COMP uses the Competition Reticle System, a 2 MOA green dot with selectable 8, 20 or 32 MOA circles. That lets you choose how much of the target the reticle covers.
How big is the window on the RONIN HE507COMP?
The Holosun RONIN HE507COMP has a large 1.1 x 0.87 in competition window, which is 28 x 22 mm. The extra glass suits practical and action pistol stages.
What footprint does the RONIN HE507COMP use?
The Holosun RONIN HE507COMP uses the Trijicon RMR footprint. It suits RMR-cut slides and competition mounts.
Does the RONIN HE507COMP have Shake Awake?
Yes, the Holosun RONIN HE507COMP includes Shake Awake with its side-loading CR1632 battery. The combination is rated up to 50,000 hours.
Is the RONIN HE507COMP magnified?
No, the Holosun RONIN HE507COMP is a 1x open reflex sight, parallax-free with unlimited eye relief. It is built on the premium Ronin platform.
What emitter does the RONIN HE507COMP use?
The Holosun RONIN HE507COMP drives its reticle with a green Super LED. That is the only functional difference from the red-emitter RONIN HS507COMP.
What is included with the RONIN HE507COMP?
The box contains the Holosun RONIN HE507COMP green dot sight, mounting hardware with a fitting tool, and a CR1632 battery.
