I have a PSA stripped upper that has a circle "O" forge mark. Does anyone know the name of the company that forged this upper? I have not seen this mark on any listings. Are you sure it's a circle, and not a square? |

My 16" CHF blemished middy upper that arrived yesterday. Circle or "O" forge mark on right side.
Any chance we can get a comment from PSA on this never before seen forge mark? |

I have had A, Keyhole, Square, and now I just built 4 new AR's from PSA and these all have the Circle on them. TBH these imo have a greater finish on them, much more standout white on the T#, the PSA logo is darkened and it is not as white as it used to be on other receiver's. No clue just yet who is forging them, but as long as we don't find out they are not of the grade metal they say to be I actually dig these. |

If it had crosshairs in the circle we could call them Armalite!

Aero Precision does not forge their own upper receivers. Very curious where this Circle-O Ranch is.

The forge mark denotes who suppled the raw chunck of forged aluminum that we machined into a receiver. It is usually not removed because of the aditional cost required to remove it correctly. It has no bearing on the quality of the finished product, as all blank forgings must pass the same specs and material inspection standards before machining.. The same forge mark may appear on any number of manufacturers, who all use different finishing processes.

This is amazing...first time in a LONG TIME we have been stumped. I'm dying to find out who the forger is and I'm betting its someone new to the game.
How is the finish/quality of these uppers? |

The Greek E is Cerro Forge's other mark. It's their European arm.
Some google evidence that Bushmaster once used an O marked upper receiver, but I haven't seen the forge mark, and can't say if it's the same. Hmm, Bushmaster, Ilion, Freedom Group? Freedom line of PSA uppers, Bushmaster/Remington/DPMS? |

There are many brass/aluminum forges which are not on The List. The Circle-O could be any one of them

I noticed that the rear flat face of the takedown lug my "o" PSA upper has a "V" marking that was applied prior to anodization for what its worth.
