XS Sight Systems Minimalist Optic Plate and Sight Set Features The XS Sights Minimalist Optic Plate and Sight Set eliminates the guesswork of pairing a separate plate and backup sight by combining both into one ready-made kit for Glock MOS pistols. The plate converts the factory MOS footprint to accept Aimpoint ACRO footprint optics giving shooters a secure purpose-built mounting interface rather than a generic adapter. Thirty percent more thread engagement than typical plates helps prevent the loosening or failure that can occur under the recoil of repeated firing. A Black Nitride surface treatment improves corrosion resistance keeping the plate protected through range use and daily carry. Front and rear sights are CNC machined from steel for durability that outlasts polymer sight options and the kit includes blue and red threadlocker along with the screws and torx bit needed for installation. The low co-witness height keeps the backup sights from crowding the optic s window so the red dot stays the primary aiming reference without visual clutter. These plates fit Glock MOS models 17 19 34 45 47 and 49 giving shooters flexibility if they move the setup between pistols. For Glock MOS owners who want a complete one-stop mounting and backup sight solution for an ACRO footprint optic this XS Sights kit delivers everything needed in a single package.
