Osight XR Review — Olight's New Enclosed Emitter Red Dot

Today we're looking at the Osight XR, a new release from Olight. It's an enclosed optic on the RMR footprint with an aspherical lens, an adjustable rear sight built right in, and a battery system that's completely out of this world. I threw it on my P320 X5 Legion — a hefty 46-ounce bad boy we haven't featured in a while — because this optic could absolutely pull duty as a competition sight too.

The glass is where a lot of optics like this fall down, and this one doesn't. It claims zero parallax like they all do, but I can truly say there's no distortion on any edge of this lens at all. No curvature, no bending, nothing. A lot of companies can produce good glass, though — what really sets this apart is the collapsible rear sight. Two little notch sights on the back push down flat and disappear, then pop back up with a button on the side. I thought it was going to be gimmicky when I first read the specs, but in practice they're very sturdy and there's a real use case: run just the dot when you want a clean window, and if you ever have power issues, boom — pop the sights up and you've got a nice co-witness with the fiber optic front.

Battery life is stupid. You're getting around 56,000 hours off a fully charged battery, and when you combine it with the charging case that snaps down on top — which also gives you a battery reading on the cover — you're looking at over 320,000 hours. I ain't a mathematician, but that's a long time. My habit with the Osights on my truck and range-bag guns is to just leave the charging cover on, so even when the optic is perpetually in motion it's not bleeding charge.

The reticle system is the best part, and I saved it for last. You guys know I'm a fan of multi-reticle systems, and this took it to the next freaking level: dot, circle, circle-dot — AND you can switch between a 2 MOA dot, a 6 MOA dot, or either one with the circle. My old podcast partner Don and I used to argue about this constantly; he's a competition guy who wants a tiny dot, and my guns are all self-defense and CCW, so I want the big dot and circle for close-range work. This is the first optic I've ever seen that ends that argument in one housing.

It's built like a tank out of 7075-T6 aluminum, with 11 brightness settings — eight daytime, three night vision — and standard windage and elevation adjustments. The 23x18 window is very nice; it's not an SRO or 507 Comp window and it's not meant to be, but it's big enough that target acquisition and transitions at the range gave me zero issues. One confession: I tried to sight it up at home by eye, and I guess my eyes are getting old, because my first shots at the range were way to the left. Adjusted it back and it was fine after that — do your zero on paper, not on your couch.

Now the killer that brings the whole package together: this optic comes in at under $300. And if you know anything about Osight, they run sales constantly — I would not be surprised to see this in the low $200s a few months after release. They had it in my hands about a month before launch for testing, and it did exactly what I had a feeling it would. Fantastic optic. Highly recommend.
