XS Sight Systems Minimalist Optic Plate Features The XS Sights Minimalist optic plate and sight combo gives Glock MOS pistol owners a single ready made solution for mounting an Aimpoint ACRO footprint optic without separate guesswork over plate and sight height. The CNC machined steel plate is engineered with 30 percent more thread engagement than typical mounting plates which helps prevent the optic from loosening or failing under recoil. A BlackNitride surface treatment is applied for enhanced corrosion resistance keeping the plate protected through repeated holster carry and exposure to the elements. The plate is designed to fit Glock MOS models 17 19 34 45 47 and 49 covering most of the MOS lineup. A tritium front night sight and a blacked out serrated rear sight are included as a true backup iron sight system with the rear sight s dark finish reducing glare and distraction in the shooter s field of view. The sight height is calculated to deliver a low co-witness keeping the sight picture visible below the optic window without crowding it. Installation hardware including blue and red threadlocker screws and a torx bit are included in the kit giving the user everything needed for a complete installation. The XS Sights Minimalist Optic Plate and Night Sight Set is available for sale at GrabAGun for Glock MOS owners who want a dependable all in one ACRO mounting and backup sight solution.
