Holosun SCS 320

Summary

This video review features Aaron from Sage Dynamics evaluating the Hollow Sun SCS 320 green dot optic. He praises the solar charging system and enclosed design. Throughout testing, the optic maintains zero after drops and rounds fired. The auto-brightness works well, although the green dot blooms under night vision. Overall, Aaron considers the Hollow Sun SCS 320 extremely durable with intuitive adjustments. He recommends it for the SIG P320 footprint as an innovative, quality pistol optic.

Takeaways

• 😀 The SCS 320 is a solar charging green dot sight from Holosun with super capacitors and a quoted 20,000 hour battery life
• 👍 The SCS 320 has performed well under various lighting conditions including daylight, twilight, low light, and no light
• 🔋The solar panel charges the battery anytime there is moderate light so the battery lasts much longer than normal optics
• 👀 The green dot is usable but a little bigger than the claimed 2 MOA size
• ⚡️ Refresh rate on the dot is fantastic allowing fast transitions between targets
• 😎 The auto adjust brightness feature works very well to adjust to changing light conditions instantly
• 😨 The dot blooms quite a bit and becomes very large under night vision due to the auto adjust
• 💪 The optic was durable after 2,000 rounds and 4 shoulder height drop tests onto concrete
• 👌 The window size is perfectly sized for rapid target acquisitions
• 🏆 Overall the SCS 320 performs very well and brings innovation with the solar charging system

Q & A

What kind of optic is the SCS 320?

The SCS 320 is a green dot, solar powered sight from Holosun with super capacitors and an internal battery that charges from any moderate light exposure.

What is the battery life of the SCS 320?

Holosun quotes a 20,000 hour battery life for the SCS 320. The internal battery charges from the solar panel whenever it is exposed to light, so the battery life is effectively perpetual barring any failure of the components.

What mount is the SCS 320 designed for?

The SCS 320 is designed as a direct mount for SIG P320 slide cuts. It fits securely with no need for an adapter plate.

How did the SCS 320 perform in Aaron's testing?

In Aaron's testing, the brightness and visibility of the dot was excellent across different lighting conditions. The auto-adjust feature responded instantly to changes in lighting. The optics also passed durability testing, maintaining zero after 2,000 rounds fired and 4 drop tests from shoulder height.

What was the main downside observed with the SCS 320?

The main downside noted was that since the optic auto-adjusts brightness, when used with night vision the dot blooms and becomes very large and bright. An adjustable brightness would improve usability for niche night vision use.

What separates the SCS 320 from other miniature red dot sights?

The standout features of the SCS 320 compared to other mini red dots are the solar charging, improved auto adjust programming, and availability in an enclosed housing direct mount for P320 slides.

What sight did Aaron compare the auto adjust function to?

Aaron compared the SCS 320's auto adjust function favorably to the Trijicon RMR, saying the early generations of RMR only adjusted based on ambient light from the rear, while the Holosun adjusts based on the target area's brightness.

What ammunition and group size did Aaron use to test accuracy?

Aaron fired 5 shot groups at 25 yards with 124 grain Gold Dot ammunition.

How tight were Aaron's groups firing the pistol with the mounted SCS 320 optic?

The groups fired for accuracy testing under bench rest conditions were very tight, indicating excellent and consistent accuracy with the mounted optic.

Does the SCS 320 come in other footprint options beyond the P320?

As of the review date, Holosun only offers the SCS 320 as a direct mount for P320 slide cuts. Other SCS models are made for different mounting systems like the Glock MOS.
