Night Fision Optic Plate 507k/407k to Glock 43x/48 MOS - Slide Adapter Plate

When your GLOCK 43X or 48 MOS build calls for a Holosun 507K or compatible micro footprint optic, the Night Fision Precision Optic Plate delivers a precision-machined 17-4 stainless steel interface specifically designed for GLOCK Slimline MOS slides — ensuring a secure, zero-retaining fit that handles the recoil of carry-caliber ammunition day after day.

The Night Fision Precision Optic Plate for 507K/407K footprint is a pistol optic mounting plate designed for GLOCK 43X and 48 MOS slimline pistol owners who need a reliable, stainless steel mounting solution for Holosun 507K, 407K, and compatible micro footprint red dot sights.

The compact dimensions of the GLOCK 43X and 48 make mounting precision critical — an imprecise plate that allows any movement under recoil will cause zero shift over time, undermining the entire purpose of a mounted optic. Night Fision addresses this by machining each plate from 17-4 precipitation-hardened stainless steel to the tightest possible tolerances, then applying a nitride finish for additional surface hardness and corrosion protection. The result is a plate that locks in against the MOS slide interface without play and maintains that fit over thousands of rounds of carry-caliber cycling. The included Night Fision Optic Tool provides the T10 Torx head needed for hardware installation and a flat-head for optic adjustments, so installation requires no additional tools. The package also includes all hardware needed to mount compatible optics to the plate.

Compatible with GLOCK MOS Slimline models — GLOCK 43X MOS and 48 MOS. Fits Holosun 507K, 407K, and other optics with compatible micro footprint. Plate thickness: 0.2". Material: 17-4 stainless steel, nitride coated. Includes plate, hardware, and Night Fision Optic Tool.

17-4 stainless steel construction provides the strength and corrosion resistance required for daily carry applications, outperforming aluminum alternatives in long-term retention under sustained recoil.

The ideal mounting solution for GLOCK 43X and 48 MOS owners running Holosun 507K or 407K optics on their carry or duty slimline GLOCK, providing a professional-grade stainless steel platform at an accessible price point.
