The MOS 3 Optic Adapter Plate Set is the essential upgrade for your Umarex-licensed GLOCK G17 Gen 5 MOS or GLOCK G45 MOS GBB air pistol. Designed specifically for GLOCK Modular Optic System (Type 3) slides, this kit allows you to mount a variety of popular micro reflex sights using four precision-cut adapter plates. Whether you're training, target shooting, or airsoft skirmishing, these plates let you customize your optic setup with ease and security.

Why choose this adapter set?

• Perfect Fit for GLOCK Type 3 Airguns: Designed specifically for Umarex-licensed GLOCK G17 Gen 5 MOS & G45 MOS GBB.
• 4 Popular Optic Footprints: Includes plates for Trijicon RMR, C-More, Leupold Delta Point Pro, and Vortex Viper optics.
• Modular Customization: Lets you choose your preferred sight setup for faster target acquisition.
• Precision Machined: Reliable mounting ensures your optic stays firmly in place during airsoft action.
• Great for Training: Mirror your real firearm’s optic layout for consistent practice without the cost of live fire.

Why not?

• Airguns Only: Not compatible with real GLOCK firearms—strictly for Umarex airsoft/airgun MOS Type 3 models.
• Model-Specific Fit: Will not fit earlier GLOCK MOS Type 1 or 2 models, or Type 3 slides not made for optics.

Pro Tip: Pair this adapter set with the Umarex RDS8 red dot sight (C-More footprint) for a lightweight and low-profile setup tailored to your GLOCK airgun. Always check plate compatibility before installation to avoid damaging your slide or optic.
