OK, added more. Have a few questions on these:Originally Posted By inburrito:Can you provide a checklist of the specific information you're looking for? I have two 6520s, one with the upper swapped out for a flattop, and would be happy to check the various markings and such if somebody can tell me exactly what I'm supposed to be looking for.I would have specific questions if I knew what serial number range yours are.Originally Posted By Spooge5150:Ekie,My GC is in the 0054XX range.A2 large pin lower and upper.

I have a Colt Gov't Carbine, I think I purchased it new in the early 90'sIts serial number is GC02091X. On the front sight is says 609, on the barrel it says 2/95 under the handguars and it is stamped C MP556NATO 1/7It has a pinned sear block that says COLT, 2 position plastic CAR stock, extractor has a blue insert. Don't see any markings on Upper Reciever, Bolt or carrier. Not sure if the front pivot hole is large or small, visually they look to be the same size, but haven't taken a micrometer to it or anything like that.Edit. I just took front pivot pin out and it will go into rear so I assume it is a small hole upper reciever.

Added yours to read like this:GC 0054XX CM upper forge code, old style receviver extention nut/receiver extention/buttstock, mag fenced lower, big pivot pin, small trigger pins, SP1 bolt carrier nope m-16, blue extractor buffer, roll marked COLT'S FIREARMS DIVISION, no sear blockIs that correct?Have a few question, was hoping you could go through it and check the following:M4 ramps? Yesfront of receiver marked M4, 4, or nothing? NothingBarrel marked C MP 5.56 NATO 1/7? YesNo marking on the barrel extention (need a flash light to check)? Has a faint '4' at 3:30Has a two digit code under the guards behind the FSB like this: Has a '2' at the front and the '0' for chromed lined at the nut.

Interesting that yours has M4 ramps and Bravo's does not. Maybe Colt ran the serial numbers out of order, or just used parts available.
If we get more data will get a better picture of the situation.Regarding bolt carriers, there were three common carriers used in Colt's semiauto line the last 40 years. What I refer to in these data bases as the SP1, the SPORTER and the M16. The SP1 has an exposed firing pin, and the back bottom part that trips the auto sear is cut off. The SPORTER carrier is what is more commonly refered to as a 'half round', and the M16 is the full auto part.Have not heard of a M16 carrier in a 1980's or 1990's factory original Colt semiautomatic.
So, is your an odd ball, or was my terminology unclear? Alright, here's the only things I know about mine. I bought two at the same time last year, but changed the A2 upper out for a flattop so I can't tell you the markings on that one.The A2 serial # is LGC 03498XThe serial # for the one that's now a flattop is LGC 03496XBoth had the M4 feedramps when stock. I see virtually no markings on the A2 upper.
