XS Sight Systems Minimalist Tritium Sight & RMR/507 Optic Plate for Glock MOS

The XS Sight Systems Minimalist Tritium Sight & Optic Plate is a two-piece, optic-ready package for Glock MOS pistols, pairing XS's low-profile backup iron sights with a precision-cut RMR/507 mounting plate in a single turnkey bundle.

The Minimalist front sight pairs a tritium-powered lamp with a photoluminescent glow dot that absorbs ambient light and emits a soft ember glow in low-light and dark conditions, giving the shooter fast target acquisition when a slide-mounted red dot is in use. The rear sight is a serrated, non-tritium notch designed to cut glare without competing with the optic's reticle. Together they present a traditional notch-and-post sight picture at low co-witness height, so the iron sights sit just below the red dot window.

The included optic plate is cut to the popular Trijicon RMR and Holosun 507 footprint, giving Glock MOS owners a direct-mount solution for their favorite reflex optic without having to stack multiple adapter plates. Finished in black, this backup-sight and optic-mount bundle is a clean, ready-to-install upgrade for any Glock MOS slide.
