Is there a thread that someone can recall with pictures of the various forge markings from uppers? Id like to be able to identify uppers at funshows if its possible.

AF = Alcoa Forge

C AF = Colt Alco Forge

C MB = Colt / Mueller Brass

Cardinal (stylized) = Cardinal Forge

CH = Colt Harvey Aluminum

CK = Colt / Kaiser Aluminum

Circle/Crooshairs w/"AR" = ArmaLite

CM = Colt / Martin Marietta

D (stylized) = Diemaco

DK = Diemaco / Kaiser Aluminum

E = Emco

EK = EMCO/Kaiser

E MB = EMCO/Mueller Brass

F keyhole = FNMI / Cerro Forge

FA = FNMI / Anchor Harvey

FK = FNMI / Kaiser Aluminum

FM = FN/Martin Marietta

FMB = FNMI / Mueller Brass

Keyhole = Cerro Forge

L = Lewis Machine & Tool

LK = LAR / Kaiser Aluminum

LM = LAR / Martin Marietta

M (under diamond) = Mueller Industries

PA = Capco / Anchor Harvey

PM = Capco / Martin Marietta

Forge codes don't mean jack.

A forge will sell uppers to numurous different companies.  The upper is then machined by the manufacturer, not the forger.  So, theoretically, the same forge could be supplying LMT and Olympic and I don't think that you'll find anybody that agrees that the quality is the same.

The only time that you can actually guage quality off of these codes is when the manufacturers code is included.  Not many companies do this.  Colt used to, but new ones are engraved, which means that they can be faked.  Diemaco and Armalite still have codes forged into their uppers.

perhaps, but lack of them is not a good sign. And it's always nice to know the origin of the forging, imo.

I just saw a square forging mark from Delton. Anyone know about this?

I don't know whose mark that is, but I have an Oly upper with the square forge mark.

ETA - Might be these guys.

I agree, that lack of a forge mark on an upper does make one go Hmmmmm...

I have:
Two LMT uppers with no forge mark whatsoever.
- 16" Standard Carbine LMT marked on left side.
- 16" Stainless Steel Fluted Mid Weight Middy unmarked.
One BCM Upper with the square (box) forge mark.
At least one Colt with the square (box) forge mark on the removable carry handle.

I kid you not!

eta: Stainless Steel on the LMT.

Oly has their own forging house and makes all their own parts and parts for others.

The square forge mark is from Brass Aluminum Forging Enterprises, as linked.
