XS Sight Systems Minimalist Fiber Optic Front Sight & RMR Optic Plate for Glock MOS

The XS Sight Systems Minimalist Fiber Optic Front Sight & RMR Optic Plate bundle gives Glock MOS pistol owners a co-witnessed, low-profile sighting solution. The set pairs a bright fiber optic front sight with a precision-machined optic mounting plate, letting the shooter run a red dot while retaining a fast backup aiming reference through the optic window.

The included optic plate is CNC-machined from steel and treated with a Black Nitride surface finish for excellent corrosion resistance and long-term durability. It delivers 30% more thread engagement than standard plates to help keep the optic locked down under recoil, and it is compatible with both factory Glock MOS plates and XS Sights plates, providing a secure low co-witness mount for any RMR-footprint red dot.

Up top, the Minimalist fiber optic front sight is set to the correct co-witness height so it sits neatly beneath the mounted optic without obstructing the shooter's sight picture. The fiber optic element gathers ambient light for a bright, easy-to-pick-up aiming point in daylight and varied lighting conditions.

Together, the front sight and RMR plate give a Glock MOS pistol a complete sighting setup ready for defensive, duty, or range use. This set fits Glock MOS models 17, 19, 22-24, 26, 27, and 31-36.
