NF OPTIC PLATE EPSC FITS GLK 43X MOS

Description

The Night Fision Pistol Optic Plate is a purpose-built adapter for Glock Slimline MOS pistols — specifically the 43, 43X, and 48 — that converts the factory Version 1 RMSc cut to accept optics using the EPS Carry footprint, most notably the Holosun EPS Carry. If your slide left the factory with the V1 MOS cut, this plate bridges the gap between what Glock machined and what you want to mount, without requiring custom slide work.

The plate is machined from 17-4 stainless steel and finished with a nitride coating. That material choice matters on a compact carry pistol: 17-4 stainless handles the repetitive impact of slide cycling without the flex or wear that can shift zero over time, and the nitride coating resists the corrosion that comes with daily carry exposure. At 0.2 inches thick, the plate adds a predictable, fixed amount of height between your optic and the slide, which factors into co-witness planning if you run suppressor-height irons alongside your red dot.

Each package includes extra mounting screws and Night Fision’s optic tool, which has a T10 Torx head sized for the included hardware and a small flathead for optic adjustments and Holosun battery compartment access. A lanyard hole lets you keep the tool tethered to your range bag or belt. One important compatibility note: this plate is designed for the V1 MOS factory cut only and will not fit 2026 Glock Slimline models equipped with the newer V2 HoloK cut. Night Fision backs the plate with a limited lifetime warranty and a 30-day return policy.
