Night Fision Optic Plate + Backup Sight Combo Features The Night Fision Optic Plate and Backup Sight Combo is machined from premium 17-4 stainless steel and held to tight tolerances ensuring the plate withstands the repeated recoil impulses of duty and competition use without loosening or shifting. The nitride coating adds a further layer of corrosion resistance and surface hardness protecting the plate against the elements and daily wear. Designed specifically for the Holosun EPS footprint the plate also accommodates other optics sharing a compatible mounting pattern giving shooters flexibility if they change red dot models down the road. Each package includes extra mounting screws and an installation tool simplifying the setup process for end users. Paired with the optic plate is a tritium front sight with a yellow front and black rear configuration designed to co-witness with most optics sharing this same footprint for a reliable backup aiming solution if the red dot fails or the battery dies. This combination gives Glock MOS owners both a precision mounting platform and a dependable iron sight backup in a single purchase. Compatible with full size Glock MOS models including the 19 17 45 and 47 the combo covers the most popular optics ready Glock platforms. The Night Fision Optic Plate and Backup Sight Combo is available for sale at GrabAGun for Glock MOS owners running a Holosun EPS or compatible footprint optic.
