I bought these as 7075 Forged Blems for a whopping $40 each

In the online pics it showed a keyhole (Cero, yes?) in the usual place but the ones I received had no markings anywhere I looked on the rear takedown pin lug first and I couldn't find anything anywhere

I think these look just fine for $40 other than some chatter marks beneath the ejection port which don't bother me at all

I just wonder if these are really 7075 ..I searched how to tell the diff between forged and cast but google gave me nothing the same for how to tell 7075 and 6061

Does anyone have a clue what I have?

Who did you buy them from?  Kind of difficult to tell who actually made them without a forge mark.  Without knowing who made them, then it becomes difficult to know what material they were made from.

Bought them here (Still some left) https://moriartiarmaments.com/ar-15-a3-stripped-upper-receiver-black-anodized-ar-15-upper-black-anodized-stripped

Service and packaging were top notch and fast

I'm pretty sure they don't machine anything tho

 

It states right in their ad, that they are 7075 forgings?  I don't understand why as of late so many are doubting, in the old days you might get something that claims to be 7075 when in fact it is 6061, but I have not seen that going on in the last couple of years.

Right now, things are inexpensive and a company would not really have a reason to advertise one thing then sell another.

Bait and switch only works when somebody is actually making a lot more money doing it, that is not the case that I have seen for a while now.

Are my links not working?  When I click on them it goes to the pics and the link to seller also works...Not working for you guys?

Are uppers without any forge marks common?

Your links are not hot, let me help you out:

And yes, I have seen a lot of parts over the years without forge marks, the forge mark only tells you who forged it, it does not tell you who machined it, Cerro has been forging aluminum for a long time now and if they are saying they are 7075, I would not worry about it, build the gun and go shooting.

I have several uppers and lowers without forge marks on them.

You would have been better off searching here for this company. It is a less than stellar company owned by less than reputable people.

I'm sorry you disagree with my comments Stick, but all of the quality forged uppers I've used over the years have had forge marks (Colt, DD, BCM, Aero, RRA, Spike's, PSA, FN, etc., etc.).


I personally don't trust forged uppers without forge marks, hence my comments. The marks matter to me, as they show that at least the forgings came from known sources.




To each his own. You are right, companies machining forgings change suppliers all the time, however going from known forge marks in the product photos to no forge marks on the delivered product raises red flags for me.


 

ETA: fixed mistakes due to fat thumbs on a small iPotato screen.

No worries on being blunt you get what you pay for I know

As I said I'm waiting for the CMT UPUR-2 but after waiting weeks already and not having a clue when they will be back in stock I found these for $40 and bought them on a whim..honestly for $80 for two I wouldn't care if I had to trash them but I think they are actually not bad for the cheapest placeholders out there : )

I'll try again with the pics from my photobucket acct..not sure why they work for me but not you guys but here goes

As for the company not being good, they were to me..My order came fast USPS Priority and well packed..it was my first order from them Only thing was in the pic it showed the Keyhole mark and the ones I got had none

In the end, if you're happy with them, that's all that matters.

Best of luck to you OP.
