I went into this skeptical. Olight makes flashlights, and the flashlight-company-pivots-to-firearms-optics arc has not had a great hit rate. Worth noting up front: Osight is a separate company from Olight, headquartered in Phoenix, Arizona and run as its own enterprise focused on the competition shooting scene. The two are corporate cousins, not the same brand, and Osight has been clear they want to be evaluated on their own work rather than inherited brand equity. Fair enough. Then the Reddit and forum chatter on the XR started turning positive, Osight asked if I wanted a unit to evaluate, and I figured the worst case was a 30-minute teardown. That is not what happened.

The box is the first thing that signals Osight took this seriously. Magnetic-closure presentation packaging, foam cutouts for every accessory, four labeled compartments of mount screws covering every common slide cut, a torque key with the Osight logo, and a printed thank-you card. It is nicer than what Holosun ships and meaningfully nicer than what Sig ships on the Romeo line. That does not change how the optic shoots, but it sets expectations that Osight is not a budget operation.

The XR mounts directly to the Ruger RXM with no adapter plate. The RXM ships with a Trijicon RMR footprint cut, and the XR is built on that footprint, so it is a five-minute install. The optic overhangs the front of the slide cut slightly because the enclosed housing is larger than a stock RMR, but it does not foul ejection and the rear of the optic clears the factory red dot-height sights for a clean co-witness. For owners of any direct-milled RMR slide, this is one of the cleanest installations you can buy. Compared to the Trijicon RCR's proprietary cross-bolt mounting system, the XR's direct fitment is a non-event.

For the broader picture on which footprints fit which slides, see our best pistol red dot guide or compare the XR head-to-head with the rest of the field in our catalog comparison tool.

Zeroing was straightforward. The 1 MOA-per-click adjustments moved point of impact predictably, and the dot tracked from a chalk box at 7 yards to confirmation hits at 25 yards without any drift on follow-up groups. Across 200 rounds of mixed 9mm FMJ and a couple of magazines of 124gr +P, zero held, the housing did not loosen, and the lens stayed clean of debris. Nothing exciting, which is exactly what you want from an optic.

The window is generous for an enclosed RMR-footprint optic. Osight lists it at 0.91 x 0.71 inches, and the practical effect is that the dot is easier to pick up under recoil than a standard RMR cut. The aspherical lens shows no visible distortion at the edges, which is the spec that tells you whether a cheap optic is actually cheap or just inexpensive. The XR is inexpensive. For a wider look at slide-cut compatibility and footprint families across the field, our pistol red dot ranking breaks down which optic fits which slide cut without an adapter plate.

The reticle stack is the headline feature, and it deserves the attention. The XR cycles through five configurations: 2 MOA dot, 6 MOA dot, 2 MOA dot inside a 32 MOA circle, 6 MOA dot inside a 32 MOA circle, and the 32 MOA circle alone. Holosun pioneered the multi-reticle idea with the 507C and 509T, but neither of those lets you flip between a 2 MOA precision dot and a 6 MOA fast-acquisition dot. You pick one at purchase and live with it.

The XR lets you have both. A 2 MOA dot is right for precision work, slow fire, and 25-yard confirmation hits. A 6 MOA dot is right for close work, defensive timing, and anyone whose eyes prefer a fatter aiming point. Being able to swap between them with two button presses is the kind of feature that should have been standard five years ago. The 32 MOA circle around either dot is the same competition-style reticle that the EOTech holographic guys love, just in a red dot package.

I am still deciding whether this is a gimmick. Initial read was that it was, and the magnetic cover is growing on me, but I have not made up my mind. The cover is a plastic shell with an 800 mAh battery inside that snaps onto the top of the XR housing with neodymium magnets and charges the optic from its own internal cell. The cover has an LED readout showing remaining charge for itself and for the optic. The optic itself also has its own built-in battery level indicator, which is a genuinely neat touch: you can check the charge state of the dot without snapping the cover on. You leave the cover at home in a drawer, the optic runs on its built-in battery for 54,000 hours, and when you eventually need to top off you snap the cover on and walk away.

The Holosun side of battery management is two distinct systems that get conflated. The 507C-X2 and the EPS line run a solar failsafe, which is a backup, not a charger: solar keeps the dot lit when the CR1632 dies, but it does not put energy back into the cell. I have run a 507C with a fully dead battery and the solar panel kept the dot usable indoors under normal room light, which is more than enough margin to finish a range trip and get home. The actual Solar Charging Sight system, the SCS line (SCS MP, SCS Carry, SCS 320), uses a built-in rechargeable cell that solar tops off in daylight. The Osight XR's magnetic cover is closer to the SCS approach: a rechargeable optic, but charged from a magnetic power bank instead of the sun. Both approaches work. The XR does not need light to charge, but you cannot field-swap a CR1632 in the parking lot if the cell ever does die, so if you carry the XR you charge it on a schedule.

Osight calls it the Collapsible Backup Rear Sight (CBRS). A small notch sight folds down into the optic housing when stowed and pops up if you press a release tab. The execution is clean. The mechanism does not rattle, the notch indexes positively, and the sight is co-witnessed with the bore axis when deployed. None of which makes it a good idea on a duty optic.

Moving parts are failure points. A fixed suppressor-height co-witness sight is stronger, faster to use, and does not depend on a hinge that lives inside the optic housing. The Ruger RXM ships with red-dot-height sights from the factory, and they already co-witness through the XR window without folding anything out of anywhere. The CBRS is a nice-to-have for a slide cut that shipped without a rear sight, but it is not a reason to choose this optic and you should not plan around it.

Halfway through this range trip it started raining. The XR did not care. The slide and frame were beaded with rainwater within minutes and the dot stayed bright through the rest of the string. My everyday carry optic is a Holosun SCS Carry, an enclosed solar-charging sight on the EPS Carry footprint, and I moved to it specifically because every open-emitter pistol red dot I had run before that had the same failure mode: water, lint, and unburned powder find the LED window and the dot dims or disappears until you clean it. I have had it happen. Once you have lost the dot mid string because of water on the emitter, the case for an enclosed housing writes itself.

Going forward, any pistol red dot I buy is enclosed. The XR checks the box at $299 with an IPX7 rating and a fully sealed window. The next step up is the Holosun 509T at $549-$649 with a longer reliability history, or the Trijicon RCR and Aimpoint ACRO P-2 at double the XR's price. The XR is the cheapest serious enclosed option on the market, and that matters because the enclosed format used to be a premium feature. It is not anymore.

At $299, the Osight XR is the best value in an enclosed, multi-reticle, RMR-footprint pistol red dot on the market right now. The reticle swap is genuinely useful. The magnetic charging cover is clever and works. The packaging and included hardware punch above the price. Initial range work held zero through 200 rounds, the window is generous, and the lens is clean of edge distortion. The footprint compatibility is the biggest thing it has going for it: any pistol cut for an RMR gets a duty-class enclosed optic with no plate.

The optic is not perfect. The collapsible backup sight is a gimmick and adds a moving part where a fixed co-witness would be stronger. The rechargeable battery means you cannot field swap a CR1632 in a parking lot if the cell ever dies. And Osight as a brand has not been around long enough to match Trijicon or Aimpoint on duty-cycle reliability data, which is the only data that matters for an optic you bet your life on.

For now, the Osight XR is staying on the RXM as my range and competition pistol setup for sustained testing. I am still carrying a Holosun SCS Carry every day, because the SCS has earned that slot through years of round count, and the XR has not. That is not a knock on Osight, it is just that trust is built by time. If the XR holds up through the next year of shooting, there is a real argument that Osight becomes the new Holosun at this price point. Either way, this is a strong competition optic with a big window and an enclosed emitter, and at $299 it is hard to argue against.
