[ARCHIVED THREAD] - making ar barrels

I would like to build a few from blanks, where can I find a list/print of the numerous dimensions I will need to deal with? All lengths. Thanks

Yeah, I spent hours (literally) looking for such a list. Found bits and pieces but nothing at all comprehensive. Ended up measuring samples and guesstimating.

No offense meant.
If you have to ask, you may not have the skills or tools to do so.

If you possess these. Reverse engineer the barrel

Hope I could help

As much as I hate their company for the spiral fluting patent BS, ERshaw can make them. Wilson or Shilen blanks have been available in the past.

Thanks for the replies.
I own a tool & die shop.
Reverse engineering often leads to tolerance stacking, unless you have a perfect example or standard.
What about the M4 prints, are they not out there?

That changes everything. You could call some of the folks that assemble barrels and just ask them. Frank White has always been a good resource.

Try asking if they won't share the info, try another. Some have said to have made barrels on this site. I'd thought of contacting them. I have a straight taper Shilen .270 blank I need to get rid of.
