Thread pitch of AR15 barrel?

[peckerwood]

What is the thread and pitch of the AR15 barrel...at the chamber...specifically the barrel extension for the locking lugs.

What thread and thickness etc?

 

[peckerwood]

Nobody know what the thickness and thread is around the chamber of an AR15 barrel?

Most people dont do that sort of work...

Well...I posted a similar thread in gunsmithing...so perhaps the regulars over their would know.

You can delete this thread if you wish Kev

I had seen it before - when trying to explore Cdn made AR15 barrels -- so I knew it was one of the AR15 barrel makers I had bookmarked
