[ARCHIVED THREAD] - Sig 556R barrel question

Posted: 10/4/2012 10:32:29 AM EDT

The 7.62x39 one. Is it unlined, melonited, chrome lined, what? I've heard conflicting things.

No one?

Button rifled, nitride treated.

Thanks. If you don't mind my asking, where did you ascertain this info? I called Sig and the guy said it was chrome lined; called One Source Tactical (Suarez's place and has factory new ones from Sig) and they said the same thing you did. Pretty sad when (if?) the damn factory gave me the wrong info!

It is Nitrided and button rifled. Shoots great!
