I was working the LE demo day at SHOT this year and saw a guy with a sterile lower who said it started life as an 80% lower that he finished himself. It intrigued me enough to start looking into 80% lowers and their finishing but I need help ID’ing this specific lower. It had a Cerro Foundry mark below the mgazine release button and the above the magazine well flaring on the (shooters) right hand side of the lower. I think tatical machining sells them but their pictures are unclear. any help or confirmation would be greatly appreciated! I included a foundry mark pic in case you own one.[/span]
Uhh… You got it. It’s a cerro forging.
The Tactical Machining lowers I have were from Cerro Forge. I don’t know if all are but mine and the few others I know about are. However, the fit & quality come down to the machining process & NOT the forge.

I guess I walked into that one… I was asking to ID where I (the layperson) could purchase one. I think me calling Cerro would yield some interesting banter.
Of the ones I’ve seen, forged 80s from Tactical Machining and KE Arms had that Cerro forging mark. The mark is on the right side between the trigger and pistol grip.
If you buy a cerro forging, you aren’t going to get something that’s 80% complete. It’s just going to be a receiver blank.
Go with Tactical Machining, they’re good guys.
Thats what I was looking for thank you! never underestimate the power of M4Carbine.Net
Your question is basically impossible to answer. Several companies use those lower blanks.
