Huben GK1 Rear Sight Mount - V2

Custom reflex sight mount made specifically for the Huben GK1 pistol. This mount requires NO drilling/tapping of your GK1. It repurposes a feature on the block meant for an internal purpose for external purposes, this is on newer GK1 blocks - PLEASE SEE PICTURE to verify before purchasing! If your GK1 does not have the front feature that is circled in RED, you can purchase the Original Rear Sight Mount HERE.

*Only one customer has run into a scenario with the front block plug being loctite'd, but please check your GK1 to see if the plug at the front of the block is easy to remove with a 1.5mm allen/hex. It should back out very easily if it is not loctite bonded. If you encounter resistance and are not comfortable with breaking the loctite bond with heat, please order the Original Rear Sight Mount.

This product is 3D printed out of CF PETG - If you have questions on if your GK1 is compatible with the V2 mount, please reach out via contact.

Included will be three sets of M3 countersunk screws for attaching your red dot sight to the mount (Shield & 407/507K Pattern comes with one set of optics screws and one set of mount screws). Also, a longer rear mount screw and front mounting screw will come with the item. There are stays installed on each respective version of the mount, depending on pattern type. Installation walkthrough is here.

If you have questions on if your RDS is compatible, please make me aware of your make/model via Contact. I can make recommendations on cheaper compatible sights as well. No issues with zero shift and the benefit of not drilling/tapping your GK1 - have had great feedback from customers!

Sight mount only is for sale. *Patent Pending
