antiUSSA, I find the use of the "implied" vulgarity by misterhemi to be offensive.
Please publicly chastise him for using that "implied" filthy language.
McThank you.

Alright, its no longer "implied"

FK is just the code that has been added to the forging mould.

Other BM uppers may have FS, BK, DK, EK, FK, AF, CW, AA, FS. On them.

My A2 upper receiver had the DK code on it(Diemaco/Kaiser). And was sitting on my BM M4.

To the other posters on this thread. Are you people gonna make every legit question into a waste of bandwidth like this? Fine by me...I am sorry for Baloo, but it's gonna be locked after this one. Hope your question got answered with the above. Check out www.biggerhammer.net for more AR15 FAQ. That is where I got the forging code info from.
