Good question. Again I don't have headspace gauges YET to get a final measurement. But on an empty chamber and just screwed in finger tight, I measured .115" of threads showing. I guess it's just a cosmetic issue as I had the barrel cerakoted black and those stainless threads stick out like a sore thumb. But I ordered a long shank and my barrel nuts are the same from factory/aftermarket. I can upload a picture if that will help.

Thanks
