[ARCHIVED THREAD] - Is this a Colt upper?

Posted: 1/18/2009 11:14:10 AM EDT

I have a Sporter Competition HBAR that I rebarrelled yrs ago. I can't recall if I swapped uppers when I rebarrelled. The upper has the large front hole with the double screws but no Colt markings. There is a triangle mark near the front by the barrel. <p>

very likely yes, can you see a square with a C in it? I believe it is a colt upper from the hriangle and P

There are no other markings besides the tiny triangle mark on the right hand side near the barrel.

Dude, that is a rare and very valuable Colt large-hole flattop upper. The small stamp is a Colt proof mark. There were no forge marks on Colt's early flattop uppers.

I know this because I have two that were taken from early-production 6700s that I bought new in the late 80s/early 90s.

ETA: In looking at your bottom pic, it looks like the small mark above the triangle near the top rail may be the vestige of the square proof mark that normally accompanies the triangle.

Looks like some of the Colts I have seen and some have a slightly different stamp, but I would say yes.

I bought this rifle sometime between 1988 and 1994 but I installed a new barrel on it after I traded the first for an m4 barrel. Now that I'm certain the upper is my original Colt upper all I need is a Colt detachable carry handle (which I just found) to get everything back to original configuration. Thanks for all the help!

If you've had it for that long, then there is no question it's a Colt upper. No one else was making a receiver like that at that time.

ETA: Did you refinish it? It looks black in the pics; a Colt receiver from that period should be grey.

Color matches the lower receiver perfectly. Had to change brightness and contrast to get detail to show up.
