Best Optics For Glock MOS

The new Glock MOS or Modular Optics System is one of the most highly-anticipated evolutions of the beloved pistol manufacturer, and it consists of five different plates that mount into a recess on the slide to give you more accurate sighting. Here are the best optics for the MOS.

Best optic lens for Glock mos

Trijicon Rmr, Trj 700696 Rm06c 3.2 Moa Red Rmy Type 2 Ck Fde

  •       Weight: 1.2 oz
  •       Battery Life: 4 Years at Brightness Level 4
  •       Night Vision Compatibility: Yes
  •       Dot Size: 3.25 MOA
  •       Waterproof: 66 feet for 1 hour with plate
  •       Price: $662


Trijicon is one of the most highly-regarded manufacturers of red dot sights compatible with the Glock MOS platform. They are considered the benchmark for both construction durability as well as field performance. It can mount easily using an existing plate and needs no modifications.


The Trijicon RMR uses a cutting edge 7075-T6 aluminum alloy housing so that no matter what conditions you subject your Glock to, the Trijicon RMR will keep up without skipping a beat. It can survive temperature extremes, vibrated, dropped, and be subjected to any weather conditions you would encounter in the field.


While the Trijicon RMR is one of the leading sights, and the yardstick by which others are commonly compared, that reputation comes at a cost. They are one of the more expensive red dot sights that you can get for the platform, in this case, however, you get what you pay for.

Leupold Deltapoint Pro

  •       Weight: 1.95 oz
  •       Battery Life: Not listed, but most are saying less than RMR
  •       Night Vision Compatibility: No
  •       Dot Size: 2.5 MOA
  •       Waterproof: 22 feet
  •       Price: $449


Leupold is known for making some of the highest quality optics on the market. It features industry-leading aluminum construction, and the reflex design gives you infinite eye relief. The fully anodized finish resists any normal and most abnormal wear and tear you can subject it to.


The famous Leupold lens is multi-coated and includes the Leupold signature Twilight Light Management. This system automatically adjusts the brightness in low-light conditions to make it easier to see, which allows it to perform better under those circumstances than nearly any competing sight available.


While the expected battery life isn’t listed, fans advise that it’s slightly less than the Trijicon RMR. While that may not sound optimal, Leupold did make the battery simple to change from the top-mounted battery compartment, eliminating the need to re-zero the sight after a swap.

Burris Fastfire 3

  •       Weight: .9 oz
  •       Battery Life: Up to 5 years
  •       Night Vision Compatibility: No
  •       Dot Size: 3 MOA
  •       Waterproof: Yes
  •       Price: $229


The Burris Fastfire 3 is the third-generation RDS from Burris and is their best offering for Glocks to date. It’s well-made, solid, and able to stand up to the recoil and high rate of fire the Glock MOS can sustain. It can withstand anything you throw at it, and it will weather any environmental stressors during use. Don’t let the low price point fool you, this is an ideal budget sight for nearly any application.

Vortex Venom

  •       Weight: 1.1 oz
  •       Battery Life: 150 to 30,000 hours
  •       Night Vision Compatibility: No
  •       Dot Size: 3 MOA
  •       Waterproof: Yes
  •       Price: $250


The Vortex Venom is a highly effective RDS for the Glock MOS platform, and it won’t cost you half a grand. The construction quality of the Vortex Venom is incredible, and it’s packed with features that you’d find on many other top-tier sights.


The lens has a similar multi-coating to other leading brands, which not only protects it from damage but enhances the image quality in both low-light situations as well as the bright midday sun. You can’t beat the Vortex Venom as a multi-purpose sight; you can take it on hunting trips, target practice, or shooting competitions.

Holosun HS507C X2 ACSS Vulcan

  •       Weight: 1.5 oz
  •       Battery Life: 20,000 hours + Solar Backup
  •       Night Vision Compatibility: Yes
  •       Dot Size: ACSS Vulcan
  •       Waterproof: Yes
  •       Price: $320


For shooters looking for a more affordable alternative to the Trijicon RMR, the Holosun HS507C X2 ACSS Vulcan is one of the best options. It is incredibly user-friendly, and has big buttons for simple operation by those with larger fingers.


While the battery will last up to 20,000 hours, the battery only takes seconds to swap out via the side-loading tray and won’t require you to re-zero your sight afterward. Not only will the battery last for years, but the shake-awake feature means you can stretch that life even longer, and the solar backup ensures that you’ll never be without a reticle as long as there’s sufficient ambient light.


The only downside to the Holosun HS507C X2 ACSS Vulcan is that the emitter isn’t fully enclosed, and while debris occlusion is possible in some extreme cases, it’s still highly unlikely.

Holosun HS507K X2

  •       Weight: 1 oz
  •       Battery Life: 50,000 hours
  •       Night Vision Compatibility: 10 daylight & 2 night vision settings
  •       Dot Size: 2 MOA Dot & 32 MOA Circle
  •       Waterproof: Yes
  •       Price: $296


Just like the 507C, the Holosun HS507K X2 is one of the best red dot sights available, and it’s also the second one from the Holosun brand that we’ve featured here. This lightweight powerhouse has all the same features as the 507K, plus some extra features and concealment benefits.


You still get incredible battery life, and while the 507K doesn’t have the solar backup that the C has, it still has the Shake Awake feature that Holosun users love. It turns off with inactivity and back on again in an instant when you pick up your pistol. Additionally, the brightness memory will retain the most-recently-used setting.


The 507K was designed with a focus on concealability. It has a super light weight of only an ounce, and it has the same ultra-durable 7075-T6 aluminum housing that’s been downsized slightly and rounded off to give a snag-free holster draw.

Shield RMSc

  •       Weight: .6 oz
  •       Battery Life: 2-3 years, >4 years in dark storage
  •       Night Vision Compatibility: yes
  •       Dot Size: 4 or 8 MOA
  •       Waterproof: Yes
  •       Price: $400


The England-based Shield Sights has released an aluminum-housed red dot sight with a polymer lens. The lens has a coating that helps cut glare and eliminate reflections, and while some shooters claim polymer lenses are easier to scratch, you do have to subject them to some considerable abuse.


There are two versions of the Shield RMSc, depending on what size reticle you want. The primary model has an easy-to-see 4 MOA dot, and for highly effective defensive shooting, there’s a model with a chunky 8 MOA dot that you just can’t miss.


While there aren’t any specified adjustment levels for the reticle brightness, the illumination is managed automatically based on the surrounding lighting conditions. It’s one of the more costly sights out there for the MOS series, but adherents say it’s well worth it.

Sig Sauer Romeo Zero

  •       Weight: .4 oz
  •       Battery Life: 20K hours
  •       Night Vision Compatibility: no, 8 daytime settings
  •       Dot Size: 3 MOA
  •       Waterproof: Yes
  •       Price: $200


Sig Sauer is one of the greatest pistol manufacturers out there, and they have recently broken into optics manufacture as well. One of the products of this diversification is the Romeo Zero RDS, which may be one of the best red dots you can get for a relatively modest price.


Many people may prefer the aluminum housing of other sights, but they’ll pay for that with added weight. The Sig Sauer Romeo Zero has a polymer housing and lens, making it an absolutely feather-light RDS entry.


The battery can give you a massive 20,000 hours, and with the motion activation feature, you can spread those hours over an incredibly long period. There are also two models available, one with a relatively conventional 3 MOA dot and one with a considerably larger 6 MOA dot.

Crimson Trace CTS-1550

  •       Weight: 1 oz
  •       Battery Life: 20K hours
  •       Night Vision Compatibility: No
  •       Dot Size: 3 MOA
  •       Waterproof: Yes
  •       Price: $156


The CTS-1550 from Crimson Trace is one of the cheapest sights on our list, but only in terms of price. The Crimson Trace CTS-1550 features a bright 3.5MOA dot projected onto multi-coated lenses that resist scratches, fog, water, and pretty much anything other conditions you can operate it in.


The polymer housing is notched to provide absolute co-witness and comes ready to mount with the standard interface right out of the box. The manufacturer states you’ll get up to 20,000 hours out of each battery, but you won’t have to worry about adjusting the brightness, the ambient light sensor will do that for you.

Swampfox Sentinel

  •       Weight: .6 oz
  •       Battery Life: 2 years in real world
  •       Night Vision Compatibility: No
  •       Dot Size: 3 MOA
  •       Waterproof: Yes
  •       Price: $195


Another super-affordable option is the Swampfox Sentinel, which is built incredibly well for a red dot that’s under $200. The robust construction is centered around a 7075-T6 aircraft-grade aluminum alloy that is also used for some forged AR lower receivers.


The coated lens resists scratches and nearly any conditions you can use it in, from rain to mud and anything in between. It even has an IPX7 rating, so it can survive full submersion for up to 30 minutes.


The Swampfox Sentinel has two methods of illumination adjustment, depending on the model chosen, either manual or automatic. On the manual model, it can be adjusted through 10 different brightness settings, while on the automatic model, it is infinitely adjustable. It includes a photo sensor that automatically senses the current lighting conditions and keeps the 3MOA red dot perfectly illuminated.
