Holosun 407K 507K MOS Adapter Plate for Glock MOS

The Holosun 407K / 507K MOS Adapter Plate is a precision-machined mounting solution designed to securely attach compact micro red dot optics to Glock MOS-equipped pistols. This plate bridges the footprint difference between Glock’s factory MOS cut and popular micro optics, allowing proper fitment without compromise.

Machined from 7075-T6 aluminum and finished in black hardcoat anodizing, this adapter plate delivers exceptional strength while maintaining a slim, low-profile footprint. It ensures reliable optic alignment and recoil resistance for duty, training, and concealed carry setups.

Designed specifically for Holosun 407K and 507K optics, this adapter is also compatible with other RMSc-pattern sights such as the Shield RMSc and SIG RomeoZero, making it a versatile upgrade for Glock MOS users looking to run modern micro optics.

If you’re running a Glock MOS slide and want a clean, secure, and durable mounting solution for your micro red dot, this Holosun adapter plate is the correct tool for the job.
