well that was quick. Just a side note, thats not an A1 upper, A1's have a forward assist, and no shell deflector, that looks like a 604 upper with A2 handguards. what are the markings on the top of the barrel between the FSB and FH?

what about inbetween the legs of the fsb, and just in front/above the ejection port, any markings there?
I'm just curious, as I LOVE old school uppers, and a Plain Jane ole A1 configuration rifle is my favorite.
Congrats SKYWLKR, thats a nice one, now you need to find some triangle handguards for it!

look in this spot,
there should be some small, tiny markings just above and to the right of the ejection port, they may be very faint, due to an arsenal refinish at some point in time.
The CM is the forging code, that it was forged by Martin Marietta for Colt, if there is a tiny c in a square in the noted spot, it was finish machined by Colt, May possibly have a triangle with a VP in it as well.

If its got a big hole in the front, thats more than likely an SP1 takeoff. All my 603 and 604 uppers are small hole in the front.
