Upgrade your Glock 43X or Glock 48 MOS with the NDZ Performance Heavyweight Brass MOS Optic Cover Plate featuring precision laser-engraved patterns. Designed as a direct replacement for the factory optic plate, this upgrade protects the optic cut while adding durability, weight, and custom styling to your slimline Glock. Precision machined in the USA from solid heavyweight brass, this cover plate provides a rugged and long-lasting upgrade over factory components. It securely fills the MOS optic cut when a red dot is not installed, keeping your slide protected while maintaining a clean, finished appearance.

Each plate is available with 12 unique laser-engraved pattern options, giving your pistol a distinctive custom look. For additional personalization, engraved designs can be enhanced with an optional color fill pass, adding contrast and depth that highlights the precision engraving. Finished with a durable Cerakote coating for corrosion resistance and long-term wear protection, this NDZ Performance optic cover plate adds both functional protection and premium styling. Like all NDZ products, it’s backed by our lifetime warranty against manufacturing defects.
