Choosing the 6 Best Glock Sights For RMR equipped with a Trijicon RMR is important because the backup sights need to work with the optic without unnecessarily obstructing the sight picture. A suitable set can provide a visible backup aiming system while allowing the RMR to remain the primary sighting system. The ideal setup depends on the Glock model, RMR mounting method, optic plate, and desired co-witness height.
Unlike standard-height Glock sights, the 6 Best Glock Sights For RMR are generally taller so that the front and rear sights can be visible the rough or above the optic window. However, not every tall sight produces the same sight picture. Some are designed specifically for a lower-third co-witness, while traditional suppressor-height sights may occupy more of the optic window. Night Fision, for example, offers different blade heights specifically to accommodate different RMR mounting configurations.
When selecting the 6 Best Glock Sights For RMR, durability, visibility, tritium illumination, sight height, and compatibility are all worth considering. A good set should remain useful if the optic becomes unavailable while still being unobtrusive during normal RMR use.
6 Best Glock Sights For RMR
Below are the 6 Best Glock Sights For RMR options and configurations to consider for Glock pistols equipped with an RMR.
1. Night Fision Optics Ready Stealth Series for Glock
The Night Fision Optics Ready Stealth Series is specifically designed around the needs of handgun optics. Rather than simply making conventional sights taller, Night Fision developed the Stealth Series to provide a less-obstructive co-witnessing setup with red dots. The company offers multiple blade heights, allowing users to match the sights to their particular optic and mounting configuration.
For a Glock with a Trijicon RMR, Night Fision lists a 330–353 blade-height option for a lower 1/3 co-witness in certain Glock configurations. This makes the series particularly useful for shooters who want their backup sights visible without having tall iron sights dominate the RMR window.
The Stealth Series uses tritium illumination, giving the sights a visible reference in low-light conditions. Machined serrations on the sights help reduce glare, while the wider rear notch is intended to provide additional daylight around the front sight. These design elements can make the iron sight picture easier to acquire when the RMR cannot be used.
Another useful feature is the set-screw design, which can simplify installation compared with some conventional sight designs. However, proper installation and verification remain important, particularly because the correct sight height depends on the exact optic and mounting system.
Features
- Optics-ready design
- Tritium illumination
- Multiple blade heights
- Wider rear notch
- Machined anti-glare serrations
- Designed for co-witnessing with pistol optics
Pros
- Excellent RMR compatibility options
- Multiple height choices
- Bright tritium aiming points
- Low-profile optics-oriented design
- Durable construction
Cons
- Some configurations may require professional installation
2. Trijicon Suppressor/Optics-Ready Night Sight Set for Glock
Trijicon is well known for producing pistol sights designed for demanding applications, and its Glock-compatible night sights are a natural consideration for an RMR-equipped pistol. The key advantage of using an optics-ready or suppressor-height configuration is that the iron sights remain visible when a slide-mounted optic is installed.
These sights are particularly useful when the user wants a backup sighting system that remains available through the optic window. Tritium illumination provides a reference in low-light environments without requiring batteries, which can be useful when the RMR is unavailable or not illuminated.
The steel construction also provides a substantial upgrade over the basic polymer sights found on many Glock pistols. Steel sights are generally better suited to repeated use and are less susceptible to the deformation that can occur with polymer sights.
However, the exact Trijicon sight height needs to be matched to the RMR installation. A direct-milled RMR and an RMR installed on a Glock MOS plate can position the optic at different heights. Therefore, the same iron-sight height should not automatically be assumed to work for every Glock/RMR combination.
Features
- Tritium illumination
- Steel construction
- Optics-compatible configurations
- Glock-compatible options
- Designed for low-light visibility
Pros
- Strong construction
- Excellent low-light visibility
- Well suited to optics-equipped pistols
- No battery required for tritium illumination
- Established sight manufacturer
Cons
- Some configurations can occupy more optic-window space
3. AmeriGlo Tall Suppressor Height Sight Set for Glock
AmeriGlo offers a wide range of Glock sights, including taller configurations intended for use with suppressors and slide-mounted optics. These sights are a practical option for Glock owners looking for an elevated iron sight picture without moving into the highest-priced sight category.
The taller profile allows the front and rear sights to remain visible when an RMR is mounted on the slide. This is particularly important because standard Glock sights may sit too low to provide a useful backup sight picture through the optic.
AmeriGlo also offers different configurations, including tritium and contrasting sight arrangements. This gives users flexibility when choosing between low-light illumination and a high-contrast daytime sight picture.
One thing to keep in mind is that “suppressor height” does not automatically mean the sights will produce the exact co-witness you want with an RMR. The optic’s height above the slide, the plate thickness, and the depth of the optic cut all affect the final sight picture. Night Fision’s measurement guidance similarly emphasizes accounting for optic height, plate thickness, and milling depth when selecting a blade height.
Features
- Tall Glock-compatible profile
- Optics-ready configurations
- Tritium options available
- Steel construction
- Multiple sight configurations
Pros
- Good value
- Wide selection
- Strong steel construction
- Useful with slide-mounted optics
- Several illumination configurations
Cons
- Exact co-witness varies by setup
4. XS Sights R3D 2.0 Night Sights
The XS Sights R3D 2.0 series is another option for Glock owners who prioritize visibility, particularly in low-light conditions. The sights use tritium illumination and are designed to provide a straightforward three-dot sight picture.
The front sight is intended to stand out clearly from the rear sights, helping the eye locate the front sight quickly. This can be useful as a backup system when using an RMR because the iron sights should remain recognizable without becoming unnecessarily complicated.
Construction is another important consideration. The R3D 2.0 sights are built for pistol use and offer a substantial upgrade over standard polymer Glock sights. For users who want a conventional iron-sight picture alongside their optic, this design provides a familiar arrangement.
When choosing R3D 2.0 sights for an RMR-equipped Glock, users should pay close attention to the available height and configuration. Not every R3D 2.0 setup is automatically suitable for every RMR installation. The correct height should be confirmed for the particular Glock model and optic mounting arrangement.
For shooters who place a strong emphasis on illuminated backup sights, the R3D 2.0 is an option worth considering. It combines a conventional sight picture with tritium illumination in a durable package.
Features
- Tritium night sights
- Three-dot configuration
- Durable construction
- Glock-compatible options
- Designed for enhanced visibility
Pros
- Strong low-light visibility
- Familiar three-dot design

5. TruGlo TFX Pro Tritium/Fiber-Optic Sights
The TruGlo TFX Pro combines fiber-optic and tritium illumination to provide visibility in both daytime and low-light environments. This combination makes the sight particularly interesting for users who want their backup irons to remain highly visible under changing lighting conditions.
Fiber optics can provide a bright sight picture in daylight, while tritium continues to provide illumination when ambient light decreases. Having both systems in one sight can reduce the need to choose between a dedicated fiber-optic setup and conventional night sights.
The TFX Pro also uses a durable construction intended for handgun use. For a Glock equipped with an RMR, the sights can serve as a backup aiming system if the optic is unavailable.
As with the other options on this list, the important consideration is sight height. A standard-height TFX Pro configuration may not provide the desired co-witness with an RMR. Glock owners should therefore confirm the specific TFX Pro model and height before purchasing.
Features
- Fiber-optic illumination
- Tritium illumination
- Durable construction
- Day-and-night visibility
- Glock-compatible configurations
Pros
- Excellent daytime visibility
- Tritium works in low light

Cons
- Height compatibility must be verified
6. Night Fision Optics Mounted Stealth Series for Trijicon RMR
The Night Fision Optics Mounted Stealth approach is designed specifically around maintaining a useful backup sight picture while keeping the irons from becoming unnecessarily prominent in the optic window. This makes the concept particularly attractive for Glock owners who want their RMR to remain the primary aiming system.
Night Fision’s Stealth Series is shorter than traditional suppressor-height sights and was developed to provide a less distracting lower co-witness with compatible optics. The company describes the design as having a wider rear notch, machined serrations, domed tritium lenses, and a set screw.
For Trijicon RMR-equipped Glock configurations, Night Fision identifies 330–353 blade heights for a lower 1/3 co-witness in its selector. However, this should be treated as configuration-specific rather than a universal measurement for every Glock and RMR installation.
The lower profile can help keep the RMR window relatively open. This is useful for users who dislike having tall iron sights occupy a large portion of their optic window while still wanting visible backup sights.
The main advantage of this setup is therefore its balance between backup capability and unobtrusive RMR use. Before ordering, users should confirm their exact Glock model, RMR mounting method, and required blade height.
Features
- Low-profile optics-ready design
- Tritium illumination
- Lower 1/3 co-witness options
- Wider rear notch
- Anti-glare serrations
- Multiple blade heights

Factors to Consider When Choosing the 6 Best Glock Sights For RMR
Sight Height
Sight height is arguably the most important consideration when pairing Glock irons with an RMR. The sights need to be tall enough to appear through or above the optic window, but excessively tall sights can obstruct more of the window. Night Fision’s RMR guidance lists 330–353 blade heights for certain lower-1/3 configurations.
RMR Mounting Method
Determine whether your RMR is installed directly onto a milled slide or through a Glock MOS plate. The mounting method changes the optic’s height above the slide, which can change the required iron-sight height.
Tritium vs. Fiber Optics
Tritium sights are designed to remain visible in low-light conditions without batteries. Fiber-optic sights are particularly useful during daylight. Combination sights use both technologies and can provide broader lighting versatility.
Front Sight Visibility
The front sight should be easy to distinguish from the rear sight. High-contrast front sights can make the backup sight picture easier to acquire, particularly when transitioning between the RMR and irons.
FAQs about the 6 Best Glock Sights For RMR
- Can I use standard Glock sights with a Trijicon RMR?
Standard-height Glock sights are generally too low to provide a useful co-witness with an RMR mounted on the slide. Optics-ready or taller sights are normally used when a visible backup sight picture is desired.
- What height sights do I need for a Glock with an RMR?
There is no single universal height. The correct height depends on the Glock model, RMR version, optic cut, mounting plate, and desired co-witness. For some Glock/RMR configurations, Night Fision lists 330–353 blade heights for a lower 1/3 co-witness.
- Are suppressor-height sights good for an RMR?
They can be, because they are tall enough to remain visible over a slide-mounted optic. However, very tall sights can occupy more of the RMR window. An optics-specific lower-profile sight may be preferable if minimizing obstruction is important.
- Do Glock MOS pistols need taller sights for an RMR?
Usually, yes, if you want the irons to co-witness with the RMR. However, the exact height depends on the MOS plate and optic configuration. The RMR plate thickness and optic position should be considered before purchasing sights.
Conclusion
The 6 Best Glock Sights For RMR, for an RMR should provide a dependable backup sight picture without unnecessarily interfering with the optic. Sight height, RMR mounting method, co-witness preference, illumination, and construction are the major factors to evaluate before making a purchase.
Most importantly, do not choose Glock sights solely by the product name or the term “suppressor height.” Confirm the exact RMR mounting configuration and required sight height first. A properly matched set should leave the RMR as the primary aiming system while keeping the iron sights available as a reliable backup.
