Mk23 Socom NBB Upper RIS adaptor

(14 reviews) Write a Review

Easy fitment of a mini sight to he Mk23. Clips onto the rear sight post. The clamping action of the sight provides the clamping force.


Please note, it has come to attention that the latest TM batch released October 2017, has a difference in the rear sight post dimensions. This means the rail clamping action is greatly reduced. In this case, We advise the RIS adapter is bonded into place.

STI, Pre OCT 2017, and ASG are unaffected.

    I mounted this on my MK23 with no problems. It wiggles very little but it is an easy fix. I wrapped a zip tie around it and it is solidly fixed to the gun. I put a reflex sight on it and it has no problem supporting its weight. An acog sight is the heaviest it will support.

    Excellent piece of kit that allows you to add a red dot sight, highly recommended.
