Used this to attach a +1 MXT Extension Kit from Nordic Components, After swaging and polishing the dimples from the Remington Magazine, everything worked fine on my new Tac-14.

Brownells USA Great product 10/01/2018

I have this nut, and extension tube and barrel clamp/ qd mount front Nordic components and they are all high quality products. I only have 4 stars because they are over priced, but still very solid products.
