5KU FIBER OPTIC RMR MOUNT BASE – GLOCK SERIES
CNC ALUMINUM • ANODIZED FINISH • REAR SIGHT REPLACEMENT • INTEGRATED FIBER OPTIC SIGHT ELEMENTS
Add an optic mounting interface to your compatible GLOCK-style gas blowback airsoft pistol with the 5KU Fiber Optic RMR Mount Base – GLOCK Series.
This rear-sight replacement combines a CNC-machined aluminum body with integrated fiber optic sight elements and an interface for selected RMR-pattern miniature reflex sights. Confirm both pistol and optic compatibility before ordering.
REAR SIGHT REPLACEMENT DESIGN
The mount replaces the rear sight on compatible GLOCK Series GBB airsoft pistols, providing an alternative to an external rail-mounted optic arrangement.
Fit depends on the replica’s rear sight mounting dimensions and slide configuration. GLOCK-style airsoft pistols from different manufacturers can use different attachment designs, so this is not a universal-fit accessory.
CNC-MACHINED ALUMINUM CONSTRUCTION
The CNC-machined aluminum body provides a metal mounting structure in a compact format. Its anodized finish gives the component a consistent exterior appearance.
Check fit and mounting alignment during installation. Cosmetic wear can occur through normal handling and contact with surrounding equipment.
INTEGRATED FIBER OPTIC SIGHT ELEMENTS
The mount assembly incorporates front and rear fiber optic sight elements, adding visible aiming references alongside its optic mounting function.
Fiber optics use available ambient light and do not require batteries. They do not provide their own illumination, so visibility depends on lighting conditions.
Do not assume that these elements will co-witness with every optic or align with every pistol’s original front sight. Sight height and clearance depend on the complete configuration.
RMR-PATTERN OPTIC INTERFACE
The mounting interface is intended for selected RMR-pattern miniature reflex sights.
Before choosing an optic, confirm its footprint, screw requirements and housing clearance. A similar appearance or an “RMR-style” description alone does not establish compatibility.
An optic and additional mounting hardware are not confirmed as included in the supplied product information.
