| I recently picked up a stripped A2 upper receiver that I would like to roughly ID. It has a black (not gray) finish, keyhole forge mark and looks like dry film lube inside. I know there is no way to tell the exact manufacturer with no more info then this, but I was just looking for a list of which manufacturers this could be from. TIA |

Everyone knows that parts assemblers use more than one of the raw forgings from the various foundries. Your list is not conclusive. |

TIA There is no way to determine who machined & finished your upper. Other than you already know who put out the raw forging. |

I know that it cannot be determined who machined and finished my upper (as I stated in my original posted which you quoted). I was simply asking if anyone had a list of which manufacturers use 'keyhole' marked forgings and put dry film lube inside. Something like "companies x, y & z use cerro forgings and dry film lube". |

Whoa Warpig!!!!!!!
I merely provided a list of manufacturers/assemblers that have used the various raw upper receiver forgings based on what I have been able to confirm. It was not intended to be conclusive. I never made any claim as to who machined them. I only offered the OP half of the information he requested as I read the post. No need to get the knickers in a bunch. |

No need to get the knickers in a bunch. Your list is what is was curious about. I was not trying to figure out who machined my upper, just which mfr used these forgings. |

Can you post a pic of the dry film lube?
From the uppers with dry film lube in my collection: Bushmaster - appears gray and very evenly applied. BCM - almost cream colored. Appears splotchy. Colt - ranges somewhere between BFI and BCM in the color department. Appears thickly applied. $.02 YMMV |
