Subject line pretty much says it all. Someone correct me if I'm wrong, but my understanding is that a "late" Mk 12 Mod 0 calls for a Colt upper receiver that has the Alcoa Forge (AF) forge mark. Should have been produced around the year 2001-2002. Will also consider a Diemaco upper receiver (has stylized "D" forge mark) from the same time period since these are technically "correct" for a Mod 0. Needs to be new or like-new condition w/ no damage, deformation, etc. to the aluminum structure. Only light handling marks in the black anodized finish would be acceptable.
Please send me a PM or email [email protected]
(remove "SPAM" first) if you happen to have one available.
I also have a NIW stripped Colt cage code upper receiver available to trade if interested. Purchased a few of these recently for future builds and willing to give one up for the right trade. I can add appropriate cash.
