None of the three worked on it. . The id of factory nut is 0.855 and the nordic m1/m2 is 0.87 so it's too big to fit and won't tighten

Nordic has the nova nut along with a host of extensions on sale right now for 50% off. If you have the inside diameter I'll know if it will work and I'll order while it's half off. Otherwise I have a local machine shop that can likely make me a nut that would work.

Well it came. The id of factory nut is 0.855 and the nordic m1/m2 is 0.87 so it's too big to fit and won't tighten

Awesome. Ordered the other day. Will post video if it's successful.

Building up a 20 gauge Stoeger 3020 for my wife to use in 3 Gun. Having no luck thus far locating a +5 extension... wondering if anyone has done a mod using other components.
