Hadron Designs Mk23 NBB Upper RIS adaptor
Easy fitment of a mini sight to he Mk23
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.
