The Viridian RFX45 Green Dot Reflex Sight Black | 24 x 15.5mm 5 MOA Green Dot Reticle Made a Bold First Impression
After a decade navigating the tactical gear landscape, I’ve become pretty discerning about optics. Red dots, reflex sights – I’ve seen them all. But the Viridian RFX45 Green Dot Reflex Sight Black | 24 x 15.5mm 5 MOA Green Dot Reticle piqued my interest with its promise of a crisp green dot and a rugged build, specifically targeting the growing demand for ACRO footprint compatible optics.
My need stemmed from a new pistol build; I wanted a small, robust optic that could stand up to everyday carry and occasional competition. I was looking for something better than the usual entry-level red dots.
The unboxing was impressive. The Viridian RFX45 felt solid, the machined aluminum giving off a sense of quality. Its compact size and lightweight design immediately made it a strong contender.
I considered the Holosun 507K and the Trijicon RMRcc. The Holosun offered more reticle options, but I wanted to try Viridian’s green dot technology. The RMRcc is the gold standard, but I wanted to explore other options. Ultimately, the RFX45’s ACRO footprint and the promise of a vibrant green dot won me over. I was genuinely excited to put it through its paces.
Real-World Testing: Putting Viridian RFX45 Green Dot Reflex Sight Black | 24 x 15.5mm 5 MOA Green Dot Reticle to the Test
First Use Experience
My initial testing took place at my local outdoor range. I mounted the Viridian RFX45 on my Glock 19 MOS using an ACRO adapter plate. The first shots were impressive, the 5 MOA green dot was easy to acquire, even under the bright midday sun.
We had variable weather conditions, the wind kicked up dust, and it started to drizzle. The IPX6 waterproof rating held true, the optic functioned flawlessly despite the light rain. The side-mounted controls were easy to manipulate with gloves on.
The sight was easy to zero; only minor adjustments to windage and elevation were needed. Acquiring the target was much faster than with iron sights, making follow-up shots quicker and more accurate. There were no unexpected issues, just smooth and reliable performance.
Extended Use & Reliability
After several months of consistent use, the Viridian RFX45 has proven to be a reliable optic. It has seen action in several IDPA matches, countless range days, and even a few days hiking, mounted on my AR pistol. There are no signs of wear and tear beyond some minor scuffs on the housing.
The Machined 6061 Aluminum with Hardcoat Anodization has held up incredibly well against impacts and scratches. Maintaining the sight is straightforward; a quick wipe-down with a microfiber cloth keeps the lens clean. Compared to cheaper red dots, the RFX45 surpasses them in both durability and clarity.
