Very solid construction. After installation, the collimator works correctly. The 6 MOA dot is optimal for a pistol intended for dynamic shooting. For me, the green dot is better than the red one, but the color of the aiming mark is a very individual matter and it may be the opposite for others.

Unfortunately, the distortion of the aiming mark is unacceptable, and right in the middle of the window... it's a real shame because I have many Olight flashlights and was convinced that this would simply be a solid, ordinary product. For comparison, the Holosun keeps a practically perfect mark all the way to the very edges...

First impression is very positive – the product is packaged in typical Olight fashion, giving the feel of a premium class item. The set itself is also very comprehensive – they included a set of screws in 4 different sizes, and each size comes in both short and long versions (so in fact 8 sizes), which is a big plus – for example, my red dot sight fit onto a SIG Sauer P365 Fuse, which uses M4 screws (all other P365 models use M3 screws). Installing the sight in my case, directly on the slide without an additional plate, was hassle-free – the manufacturer's website describes exactly which screws are needed. The sight, at the highest brightness setting of the aiming dot, is very bright – almost dazzles the eyes, even in sunlight. The window of the sight is slightly but noticeably larger than on the Holosun EPS Carry, and the brightness control buttons have a very distinct 'click'. In general, super and the price is almost 3 times lower than the aforementioned Holosun – we'll see how it performs after testing at the range.

I bought this red dot sight for my SPRINGFIELD HELLCAT PRO. It fits perfectly. Looks SUPER. It's an ideal alternative to the Holosun EPS. I set ZERO and it hits precisely. Now let's see how it will perform over time. So far I'm really satisfied.
