Night Fision Holosun K Pistol Optic Mount Features The Night Fision Pistol Optic Mount is machined from premium 17-4 stainless steel a material chosen for its strength and resistance to the repeated recoil impulses a slide-mounted optic plate must absorb. Built to the tightest tolerances the plate ensures a secure accurate fit between the Glock 43X or 48 MOS slide and a Holosun 507K or 407K footprint optic helping the sight hold zero through sustained firing. A nitride coating adds an extra layer of corrosion protection on top of the stainless base material extending the plate s service life in humid or high-use environments. At just 0.2 inches thick the plate keeps the optic s mounting height low preserving a more natural sight picture and co-witness potential with factory iron sights. Designed specifically for Glock MOS Slimline models the plate gives owners of these compact pistols a dedicated solution for mounting a Holosun 507K or 407K pattern optic without aftermarket slide milling. Each package includes extra mounting screws along with an installation tool simplifying setup for shooters mounting their first red dot. Night Fision backs the plate with a limited lifetime warranty reflecting confidence in its stainless steel construction and machining quality. Glock 43X and 48 MOS owners looking to add a Holosun 507K or compatible footprint optic will find this mounting plate a precise durable solution available for sale at GrabAGun.
