Holosun HE503CU-GR 1x Green 2 MOA Dot / 65 MOA Circle Red Dot Sight Review

My first impression of Holosun HE503CU-GR 1x Green 2 MOA Dot / 65 MOA Circle Red Dot Sight

Red dot sights have always been a staple in my gear, bridging the gap between iron sights and magnified optics. I’ve used countless red dots over the years, from budget-friendly options to high-end tactical models, each with its own strengths and weaknesses. I was intrigued when I started hearing buzz about the Holosun HE503CU-GR 1x Green 2 MOA Dot / 65 MOA Circle Red Dot Sight, especially the green reticle.

For years, I’ve been grappling with eye fatigue during extended range sessions. The typical red reticle can sometimes blend into brightly lit targets, causing strain. I needed a durable, reliable optic with a reticle that stood out, aiding in faster target acquisition and reduced eye strain. The promise of a green reticle and Holosun’s reputation for quality at a reasonable price point drew me in.

Unboxing the HE503CU-GR was a pleasant experience. The sight felt solid and well-made, despite its lightweight design. The black anodized finish looked clean and durable, and the included mounts (low and lower 1/3 cowitness) were a welcome bonus.

I considered a few other options before settling on the Holosun. The Aimpoint PRO is a classic, but its price is significantly higher. Sig Sauer’s Romeo5 is another contender in the same price range, but I wanted to try a green reticle, and Sig Sauer did not have one in a comparable model. The Holosun offered the features I wanted – a green reticle, multiple brightness settings, and a reputation for durability – at a price that felt right.

My first impression was one of cautious optimism. I was excited to try out the green reticle, but I also wanted to see if the Holosun lived up to the hype. Only time and range testing would tell if it could stand with the high-end optics I’ve grown accustomed to, or if the lower price meant compromised quality.

Real-World Testing: Putting Holosun HE503CU-GR 1x Green 2 MOA Dot / 65 MOA Circle Red Dot Sight to the Test

First Use Experience

My initial range trip with the Holosun HE503CU-GR was at an outdoor range on a partly cloudy day. I mounted it on my AR-15, using the lower 1/3 cowitness mount, which aligned perfectly with my iron sights. The green reticle immediately impressed me.

It was noticeably easier to pick up than red dots I’ve used in the past, even against brightly lit targets. Adjusting the brightness settings was simple, and I quickly found the optimal level for the lighting conditions. I ran through a few drills, focusing on speed and accuracy, and the Holosun performed flawlessly. The 2 MOA dot was crisp and clear, allowing for precise shots, and the 65 MOA circle was great for quick target acquisition at closer ranges.

Extended Use & Reliability

After several months of regular use, the Holosun has proven to be a reliable and durable optic. I’ve taken it to several outdoor ranges, used it in a couple of training courses, and even subjected it to some light rain during a simulated hunting scenario. The Holosun HE503CU-GR has held up exceptionally well.

There are no noticeable signs of wear and tear, despite being bumped around in my range bag. The finish remains intact, and the glass is still clear. Cleaning and maintenance are simple. A quick wipe with a microfiber cloth keeps the lens free of smudges and debris.

Compared to some of the more expensive red dots I’ve used, the Holosun holds its own. It may not have all the bells and whistles of a high-end Aimpoint, but it offers excellent performance and reliability at a fraction of the cost. It definitely outperformed my initial expectations.
