Last updated June 2026 · By Nick Hall, covers red dots and pistol optics for USA Gun Shop
Quick take: Osight just dropped two enclosed-emitter pistol red dots and both are available now. The XE AMRS runs $249.99 and brings a switchable reticle system plus a folding backup rear sight, while the smaller SE comes in at $179.99 on the popular RMSc footprint. For sealed optics with these features, that pricing undercuts a lot of the established names. If you have been waiting for an affordable way into enclosed-emitter dots, this is worth a hard look.
- What they are: Two enclosed-emitter red dots, both shipping now, aimed squarely at the pistol-optic crowd that wants a sealed window without paying flagship money. See how they stack up in our roundup of the best red dot sights for pistols.
- The XE AMRS ($249.99): Headlines the lineup with Osight’s Advanced Multi-Reticle System, letting you pick a 2 MOA dot, a 6 MOA dot, or a 6 MOA dot inside a 32 MOA circle. It also has a collapsible backup rear sight built in and battery life rated from 61,000 to 105,000 hours depending on settings.
- The SE ($179.99): A compact, concealed-carry-focused dot with a 6 MOA dot on an RMSc footprint, which is one of the most common mounting patterns on slim carry pistols.
- Who they’re for: Carry shooters and EDC pistol owners who want a sealed, debris-resistant dot at a friendly price. If you are still deciding on a sighting system, our gun optics guide walks through the trade-offs.
Why Enclosed-Emitter Dots Matter
The big draw with both of these optics is the enclosed-emitter design. On a standard open red dot, the LED emitter sits exposed and shines up onto an open lens. On an enclosed-emitter dot, that LED sits inside a sealed housing, kind of like a tiny tube, instead of being out in the open. The dot is still projected the same way you are used to, but the path is protected.
Why does that matter on a real gun? Because an exposed emitter is the spot where lint, rain, snow, and pocket debris love to collect, and when they do, they can block or smear your dot right when you need it. Sealing the emitter keeps that junk out, which is a genuine durability and reliability advantage for a pistol that lives in a holster, a glovebox, or a coat pocket. That used to be a feature you paid a premium for, which is part of what makes Osight’s pricing interesting.
The XE AMRS and Its Multi-Reticle System
The XE AMRS is the headliner, and the name spells out its trick: an Advanced Multi-Reticle System. Instead of locking you into one dot size, it lets you select between a 2 MOA dot, a 6 MOA dot, and a 6 MOA dot sitting inside a 32 MOA circle. That is a smart spread, because a fine 2 MOA dot is great for precise, slower shots, a 6 MOA dot is faster to find up close, and the dot-in-circle gives you a forgiving aiming reference for quick work.
It does not stop at reticles. The XE AMRS includes a collapsible backup rear sight, so you have an iron-sight fallback that folds out of the way when you do not need it. Battery life is rated from 61,000 to 105,000 hours depending on your brightness and settings, which is a long runway between changes. At $249.99 for a sealed dot with a switchable reticle and an integrated backup sight, it is a lot of feature for the money.
The Compact SE for Carry
The SE is the carry-minded option, and it is built smaller and simpler on purpose. It runs a single 6 MOA dot, which is the easy-to-grab size most people want on a defensive handgun, and it sits on an RMSc footprint. That footprint is the common mounting pattern you see on slim, optic-ready concealed-carry pistols, so it is going to bolt right up to a lot of popular carry guns without an adapter plate headache.
At $179.99, the SE is the value play for someone who wants the debris-resistance of an enclosed emitter on an everyday carry gun but does not need a switchable reticle or a backup sight built into the optic. It is a focused, no-frills package, and that is exactly what a lot of carry shooters are after. These are pistol-first optics, not AR units, so if you are kitting out a carbine, check our list of the best AR-15 red dot sights instead.
Aggressive Pricing in a Crowded Field
The story here is really about price. Enclosed-emitter pistol dots have become the hot category, but most of the well-known sealed options sit well above these numbers, especially once you add features like a multi-reticle system or an integrated backup sight. Osight is coming in at $249.99 and $179.99 and stacking on features, which is the kind of move that gets a budget-conscious buyer’s attention fast.
Both models also share a couple of nice quality-of-life touches: a motion sensor for motion-activated wake and sleep, so the optic powers down when it sits still and snaps back on when you grab the gun, plus 10 brightness settings to dial in for everything from a dim indoor range to bright daylight. We have not run these through our own testing yet, so the long-term durability and dot quality remain to be proven on the range. But on paper, Osight has priced these to move in a crowded field.
