Holosun HS515CM 1x 2 MOA Dot / 65 MOA Circle Red Dot Sight Review

My first impression of Holosun HS515CM 1x 2 MOA Dot / 65 MOA Circle Red Dot Sight

The red dot sight market is saturated, but the Holosun HS515CM 1x 2 MOA Dot / 65 MOA Circle Red Dot Sight immediately caught my attention with its combination of durability, versatile reticle options, and innovative solar charging. As someone with over a decade in the outdoor and tactical gear industry, I’ve seen countless optics come and go, but Holosun has consistently impressed me with their commitment to quality and innovation, and this optic seemed to be another example.

I needed a reliable and versatile optic for my AR-15 that could handle both close-quarters engagements and mid-range target acquisition. My old red dot sight lacked a clear, crisp reticle in bright daylight and the battery life was abysmal. The HS515CM’s advertised solar charging and multiple reticle system seemed like the perfect solution.

Unboxing the HS515CM, I was immediately struck by its robust construction and compact size. The matte black finish looked durable, and the included quick-release mount felt solid. The weight was surprisingly light, especially considering the features packed into this optic.

I was deciding between this and the Aimpoint PRO and the Sig Sauer Romeo5. While the Aimpoint has a reputation for bomb-proof reliability, its price point is significantly higher. The Romeo5 is a great budget option, but the HS515CM’s solar charging and circle-dot reticle sealed the deal.

My initial impression was excitement. I was eager to get it mounted and see if it lived up to the hype. The build quality felt excellent, and the features promised a significant upgrade over my previous red dot.

Real-World Testing: Putting Holosun HS515CM 1x 2 MOA Dot / 65 MOA Circle Red Dot Sight to the Test

First Use Experience

I took the Holosun HS515CM to my local shooting range for its initial test. I mounted it on my AR-15 and zeroed it at 50 yards. The adjustments were crisp and precise, and I quickly dialed in the 2 MOA dot.

I tested it in varying light conditions, from bright sunlight to overcast skies. The optic performed flawlessly in all scenarios, with the solar charging system keeping the reticle bright and visible even when the battery was depleted. It was easy to use straight away.

There were no issues at all during my first range session. I was impressed with the clarity of the glass and the crispness of the reticle. The quick-release mount also proved to be very secure, holding zero even after repeated removal and reattachment.

Extended Use & Reliability

After several months of regular use, the HS515CM has proven to be incredibly reliable. It’s been through several range trips, a weekend-long tactical training course, and even endured a few accidental bumps and scrapes.

The optic shows minimal signs of wear and tear. The finish has held up well, and the glass remains clear and scratch-free. I regularly wipe it down with a microfiber cloth to remove any dust or debris.

Maintenance is simple: occasionally cleaning the lens and checking the battery. So far, I haven’t needed to replace the battery thanks to the effective solar charging system. Compared to my old red dot, the Holosun has been a night and day difference in terms of reliability and performance.
