I bought a “FrankinGun” and I have been trying to ID what I bought!
Being a newbie to AR’s I know nothing about AR’s. I have found out, I
Have a Colt barrel, an MAG lower but the upper I get nowhere!
The only marking on the upper is an “O” to the left of the deflector.
Can anyone help??

Thanks for any help!

Is your bbl marked on the underside near the muzzle?  Is it "5.56 NATO1/7 C P"?
Pics would help.

That "O" forge code is on alot of the Colt Expanse series.  The bbl markings above are as well.

You are a wizard! I looked up Colt Expanse series and there it was!
Thank you for your help!

Wizard, no. Just happened to buy an Expanse bbl for a truck/farm gun. I've done a little research on the Expanse series.

Glad to help.

Eta: that same forge code is showing up on PSA uppers also. I have no idea who it is. Also edited my OP with bbl markings info.

you wont find the manufacturer of the upper, only the forger. unless its marked elsewhere.
my bcm is forged by anchor harvey and machined by bcm, marked BCM4 above gas tube hole.

from my quick research a circle is armalite but it should also have crosshairs in the center of the circle

post pictures.  you probably have a square (brass aluminum forging enterprise) and your drunk
