Are 20" barrels available with chrome lining? Also, are the 20" barrels a "heavy barrel" i.e. same profile in front of FSB and behind, or "government" profile i.e. get thinner behind FSB? I remeber seeing a post that covered this but i can't seem to find it now.
Heck, while I am at it- I hear you guys have 9mm uppers- is that true?
