Glock made some pretty big changes with the Gen6, and one of the coolest updates is the new Optic Ready System (ORS). Instead of carrying over the traditional MOS setup, Glock redesigned the optic mounting system to give shooters more flexibility when choosing a red dot.
This guide is specifically for Glock Gen6 pistols with the ORS cut. It does not apply to Gen4 or Gen5 Glock MOS slides, and it also does not apply to the Glock 43X MOS or Glock 48 MOS, which use a different optic mounting system.
In this guide, we’ll go over which Osight optics will fit the Glock Gen6 ORS, which footprints are compatible, and what adapter plates you’ll need to make each setup work.

Why Consider an Osight Red Dot?
Osight has made a name for itself by offering pistol red dots without pushing the price into premium-optic territory. They’ve also been pretty willing to try things that are a little different, with features like rechargeable optics with magnetic charging covers, multiple reticle options, enclosed emitter designs, and newer housing materials like OAL.
For a Glock Gen6 ORS, there are a few different Osight options to choose from depending on how you want to set up the pistol. You can go with a smaller RMSc-style optic for a more compact setup, a larger RMR-style optic for a bigger viewing window, or a DPP-footprint option if that better fits what you’re looking for.
Overall, Osight gives Gen6 owners a pretty wide range of choices at approachable price points, whether you want something smaller for carry, a larger optic for range use, or an enclosed emitter for a little more protection from dirt, moisture, and debris.
What optics footprint is the Glock Gen6?
The Glock Gen6 uses Glock’s new Optic Ready System, or ORS. This replaces the older MOS setup used on previous generations and gives the Gen6 its own optic mounting interface.
What adapter plates exist for the Glock Gen6?
One nice thing about the Glock Gen6 ORS system is that Glock includes three factory adapter plates with the pistol, so you already have a few mounting options right out of the box.
For the footprints we’re covering in this guide, the 02 plate is used for RMR-footprint optics, while the 04 plate can be used for DPP and RMSc-footprint optics. That means a lot of popular red dots can be mounted using the plates Glock already gives you.
There are also aftermarket Gen6 ORS plates available for RMR, RMSc, and DPP optics. These are typically made from aluminum instead of polymer and are designed to give you a cleaner, tighter fit around the optic. Depending on the setup, they can help close some of the visible gap between the optic and the slide compared with the factory plates.
We’ll link to our Glock Gen6 ORS Adapter Plate Finder so you can see the available options and choose the plate that makes the most sense for the optic you want to run.
Best RMSc-Footprint Osight Optics for the Glock Gen6
These optics are going to use the 04 plate that came with your Glock. RMSc optics are the smaller, less bulky option and are generally a great fit if you want to keep your setup compact. They’re especially popular for concealed carry because they add less width and weight than a full-size optic. If you want the smallest and most streamlined optic setup possible on a Glock Gen6, the RMSc options are a great place to start. Learn more about ORS-to-RMSc adapter plates.

Choosing between Red or Green Reticles
It’s common to go back and forth between red and green reticles, so here are a few practical points to help you decide which one makes the most sense for your setup.
- Green reticles are often easier on the eyes, especially during longer range sessions or extended training.
- Shooters with astigmatism sometimes see a cleaner dot in green. While results vary from person to person, many customers report that a green reticle appears more defined and less “smeared” compared to red.
- Green will not wash out on backdrops like green grass, foliage, or green colors.
- In theory, green dots can have a longer battery life because green is brighter, so for example a green dot on brightness setting 6 may be the same brightness as a red dot on setting 7 - which would save battery life.

Choosing between Open vs Closed Emitters
A simple way to think about open versus enclosed emitter red dots is to match the optic to how you plan to run your Glock Gen6.
If your Gen6 is going to see a lot of outdoor use in rain, snow, or rough conditions, an enclosed emitter has a clear advantage. The emitter is sealed inside the housing, which helps prevent water, dirt, or debris from blocking the dot when conditions are less than ideal.
For shooters running OWB setups, whether for duty, range time, or general outdoor use, enclosed optics tend to be the safer choice for that added protection and consistency.
If your Gen6 is primarily carried IWB or used in more controlled environments, an open emitter optic will serve you just fine. They are lighter, simple, and still perform well in most situations, including light weather. Enclosed designs just add an extra layer of reliability when things get messy.
Maintenance is another factor to consider. Open emitter optics can collect dust, lint, and debris over time, especially with daily carry, so occasional cleaning is part of the routine. Enclosed emitters are easier to maintain since the critical components are protected inside the housing.
