You should watch Chris Bartocci on Youtube. He is the master guru on the AR platform on all accounts. He has a video on what really happened to the M16 during Vietnam. He also wrote the books Black Rifle One and Black Rifle Two. He also highly praises the C7 saying the Canadian's implemented the rifle significantly better than the American Army. He currently works for Colt as a weapons tech and served in the US Army.
The C7 has always been a cold hammer forged chromeline chamber and bore using the H1 buffer.

Sorry guys. Mixed up my info badly.
I thought it had a thicker chrome lining than the American rifles for use in really cold weather. I think I read that in an SA20 review.
Plated the same as a C9 barrel, which is much thicker I think, Roddy.
