Night Fision Optic Plate and Backup Sight Combo Features The Night Fision Optic Plate and Backup Sight Combo gives Glock 43X and 48 MOS owners a precision mounting solution machined from premium 17-4 stainless steel built to the tightest tolerances for a secure accurate fit. The nitride coating applied to the plate adds extra protection against wear and corrosion from repeated recoil and handling. Designed specifically to accept the Holosun 507K and other optics sharing a compatible mounting footprint the plate gives shooters a dependable way to run a slide mounted red dot on their Glock MOS slimline pistol. Each package includes extra screws and an installation tool simplifying the setup process for the end user. Paired with the plate is a tritium front night sight finished in yellow designed to co witness through the optic with most sights sharing this mounting footprint. This co witness capability gives the shooter a reliable backup aiming reference in the event the red dot fails or the battery dies a critical consideration for a defensive pistol. The black rear sight completes a low profile snag resistant sight picture that works in tandem with the front tritium insert. For shooters who want both a quality optic mounting plate and a dependable backup sight in one package the Night Fision Optic Plate and Backup Sight Combo is available for sale at GrabAGun.
