⚙️ Product Details

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.
