5KU Fiber Optic RMR Mount Base for Gas Blowback Pistols (Model: SAI BLU)

5KU FIBER OPTIC RMR MOUNT BASE – SAI BLU

CNC ALUMINUM • ANODIZED FINISH • REAR SIGHT REPLACEMENT • INCLUDED RED & GREEN FIBER OPTIC RODS

Add an optic mounting interface to your compatible SAI BLU gas blowback airsoft pistol with the 5KU Fiber Optic RMR Mount Base – SAI BLU Series.

This compact rear-sight replacement combines a CNC-machined aluminum body, integrated fiber optic sight elements and an interface for selected RMR-pattern miniature reflex sights. Included red and green fiber optic rod sets give you a choice of sight colours.

Confirm compatibility with your exact pistol, slide and intended optic before ordering.

SAI BLU REAR SIGHT REPLACEMENT

The mount replaces the rear sight on compatible SAI BLU Series GBB airsoft pistols, providing an alternative to larger external optic mounting arrangements.

Fit depends on the pistol’s rear sight dimensions and slide configuration. Compatibility can vary between production versions, so the SAI BLU designation should not be treated as a universal fit guarantee.

CNC-MACHINED ALUMINUM CONSTRUCTION

The CNC-machined aluminum body provides a compact metal mounting structure. Its anodized finish gives the component a consistent exterior appearance.

Check fit and alignment during installation. Scratches and 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 aiming references alongside its optic mounting function.

Fiber optics use available ambient light and require no batteries. They do not generate their own illumination, so visibility depends on surrounding lighting.

Co-witness with a red dot sight is not confirmed for every configuration. Sight alignment depends on the optic’s height and the complete mounting arrangement.

INCLUDED RED & GREEN ROD SETS

This SAI BLU configuration includes two sets of fiber optic rods: red and green.

The colour options let you choose the sight appearance you prefer. Visibility and colour preference vary between users and lighting conditions.

RMR-PATTERN OPTIC INTERFACE

The mounting interface is intended for selected RMR-pattern miniature reflex sights.

Check the optic’s footprint, screw requirements and housing clearance before purchasing. Similar appearance or an “RMR-style” label alone does not establish compatibility.

A red dot optic is not listed among the included components. Additional mounting hardware and accessories are not confirmed as included.
