I am not TRYING to post bullshit.... just trying to accurately quote what I've read here from several different current Colt "experts" here online at AR15.com. Mine is definitlely a Colt and only says C MP(no 2nd C) 5.56 NATO 1/9 HBAR. I'm not an expert by any means, but just quoting what I've read right here. MY 6721 DOES NOT have a chrome bore/chamber, and if it did I would be posting otherwise. Maybe it's different for the LE6721 upper kits, but if you do some Searching here, I'm not the ONLY person that believes this "bullshit". I've been told MANY times from several sources, all the 1/7 Colt LE/Military barrels are chromed and the 1/9 barrels since the late '90s are NOT
like everyone else says as well.... Colt does different things with their parts.
PLEASE show us all where it says ALL 6721 1/9's are chromed
who pissed in your Wheaties??
