For those of you who have a RRA 9mm upper receiver, I am interested in what the forging marks are on the side of the receiver. Specifically what mark your receiver has. Thank you in advance.

I have an A3 model with no markings. It was purchased approx. 2 months ago.

My Rock River A2 upper has a mark next to the sight that looks kind like an "A" but with a rounded top of the "A"

One question on the mark that looks like an "A" with the top rounded. Does it look like a keyhole? The usual markings on forgings are the keyhole, an "A" that is split, an "AF", two letters ending in "K", or no mark at all. Again, thanks for the help on this question to all. Garrison Mfg. Inc.

All of the marks are the forging company's mark. By identify the different marks we can figure out who has the forging die for that specific upper receiver. Garrison Mfg. Inc.
