Installation notes:

• The shortest screws (M3×6) are used to attach the plate directly to the Glock MOS slide.
• Screws M3×8 and M3×9 are used to fix the optic to the plate, depending on the specific Holosun model you are installing.
• Begin by threading each pair of screws gently by hand without excessive force, then tighten them gradually to the specified torque value.
• The conical heads of the screws automatically center the red dot sight along the bore axis.
• All screws must be secured with a suitable thread locker such as Loctite 243 to prevent loosening during use.
