I have a NIB Pre ban model 6700 Competition HBAR, the barrel is marked C MP 5.56 NATO 1/9 HBAR. Is this barrel chrome lined ? Biggerhammer says the C stands for Colt, previos post on this forum say just the chamber is lined and not the bore. Anybody know for sure?
Let me add to this. My serial # is CH160xx. I have owned a SP1(1982), a Delta HBAR (1987), a HBAR(1989), a target sporter (1993) and a Lightweight(1992). All had a chrome lined barrels and it was easy to tell that they did. The chamber end was counter sunk and had a shiny 1/8 inch ring around it. The muzzle end had a shiny ring around the end of the barrel.
The chamber on my Competition HBAR is counter bored about .015 (so there is a step there) . No shiny ring around it. The muzzle is also counter bored about .015 . Both ends of the barrel are black, with only the bore and chamber metal colored.
Anybody have one of the Colt AR's with the 24 inch stainless barrel ? What are they stamped?
