AR15/M16 barrel blueprint

**KalleBalleSvartSk@lle** · 02-22-2005

Anyone who can help me locate a blueprint for either a carbine or rifle length Ar15/M16 barrel, or maybe both?

Like that?

I have M4 barrel profile:

for 20" barrels I found THIS but all are custom profile ( not govt )

Thanks, the m4 profile was exactly what I was looking for, though I'm thankful for any other blueprint or sketch with dimensions shown.

If anyone can contribute with the proper diameter of the holes for the gas block pins and where they're supposed to be, I would be even happier

you should ask at ar15.com

Maybe I should, but I hoped to save the trouble of registering at yet another board, though I've started to dig through the posts there.
