I have an upper receiver I bought from a policeman friend of mine, and I don't know who manufactured it.Hopefully, ya'll can help.

It is an A2 upper.On the right side of it,all the way in the back of the carrying handle is a keyhole shaped marking with three dots inside.On the front sight base on the right side is the letter "F" followed by either R1 or RI inside a circle and then the number 2.
 Anyone have any idea what I have?Any help identifying it would be appreciated.

Thanks,
Crimefighter

IIRC, three dots and a keyhole means you have an Olympic Arms A2 upper.
