The threads are both 5/8x18. I haven’t crossed them from rifle to rifle. I gotta find the one that has the 5/16 head now. I think it’s on my other
Doc White is a pretty sharp cookie and if he changed the length/height of that nipple i would say it would WORK for ALL his models produced . Thats just common sense to do so . Im with Ed on this that it wont matter . Besides Doc would have specified differently if it did matter long ago .I gave Jeff 5 breechplugs that came from Whitetails, 3 other M97’s and 1 M98 that were built at different times to come up with the final prototype. They all looked the same and all were interchangeable in all of my White ML’s. I can only assume the one that looks different came from Doc’s original design of the Super91. Only Doc could possibly answer that question.
