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.

    Mk23 top rail

    Posted by Joe on 23rd Mar 2018

    This rail fits nicely, there is no need to add any adhesive for it to work properly, but being the stickler I am, I added glue and now it's super solid. If you want a red dot or similar, I would recommend this rail.
