Upgrade your aiming game with the MOS 1 Optic Adapter Plates, designed specifically for Umarex licensed GLOCK Type MOS 1 airguns and airsoft pistols. This 4-plate kit allows users to mount the most popular pistol red dot sights on their Modular Optic System (MOS) ready GLOCK air pistols, giving you the versatility and performance of modern optics.

Why choose this kit?

• Tailored Fit: Designed exclusively for GLOCK Type MOS 1 air pistols—ensures a secure, proper fit without modification.
• Wide Compatibility: Supports major optics brands including:
  • Vortex Viper / Docter Sight C
  • Trijicon SRO
  • C-More STS 2
  • Leupold Deltapoint / Shield RMSx/c
• Precision Machined: Quality construction ensures repeatable zero retention and durability.
• Easy Installation: Swap optics quickly and easily using the included adapter plates.
• Perfect Pairing: Works well with the Umarex RDS8 red dot sight for a lightweight and low-profile setup.

Why not?

• Limited Compatibility: Only works with MOS 1 models—not compatible with MOS 3 or air-powered GLOCKs that include optic plates.
• No Optic Included: This kit provides adapter plates only; red dot sights must be purchased separately.
• Model-Specific: If you're unsure which GLOCK model you have, double-check compatibility before purchase.

Pro Tip: Match the adapter plate to your optic before installation to avoid unnecessary swaps. If you’re using an RDS8 or similar compact red dot, plate 04 (Leupold/Shield RMS) often gives the lowest mounting height for improved co-witness and quicker target acquisition.
