Shadow Ops Weaponry

Not arguing with your statement and I don't have intimate knowledge of CNC machines but if two companies are running the same software/CAD file for the lower, would'nt the marks be the same? I got billet alluminum lowers from them, not forged. Maybe that is where we are seeing two different things, which would support what both of us are saying?

He was talking about forged lowers, of which most all of the forged lowers made are made from a couple of different forgings/forging companies. Kinda like car batteries, there's only about 5 actual manufacturers in the country that make car batteries (outside of exotics like Optima, etc and for this discussion, consider them like the billet lower mfg's) but there's hundreds of different "brand names". These few mfg's either sell 80% or raw forgings to vendors that finish them out, or they finish them on site to customer spec and roll mark with customer's info.

Info from an Arfcom post that explains some of it here's a link http://www.ar15.com/forums/t_3_12/31...mpared___.html

Not all inclusive, and a few brands have had more than one manufacturer cut their receivers. Many companies receive CMT and LMT cuts in the white and finish them themselves. I have not seen a LAR or MMS cut that was finished by a third party company.

LMT = LMT, Lauer(old), DS Arms, PWA, Eagle, Knights Armament, Barrett, Bushmaster (?)
CMT = Stag, RRA, High Standard, Noveske (old), Century (current), Global Tactical, CLE, S&W, MGI (1st batch), Wilson Tactical, (some?) Colt, Ratworx
LAR = Grizzly, Bushmaster (L Prefix), Ameetech, (?)DPMS, CMMG, Double Star, Fulton, Spike's Tactical, Noveske (new)
MMS = Mega, Gunsmoke, Dalphon, POF (forged), Alexander Arms, Stinger, Spike's Tactical(old)
JVP = Double Star, LRB
Olympic = Olypmic, SGW, Tromix, Palmetto, Dalphon, Frankford, (old) Century
Superior = Superior Arms, Lauer (current)
Grenadier Precision
Sabre Defence (?)

Now Billet receivers is a whole other ball game and all the info goes out the window as to weather or not they're using someone else's CAD files, or their own, or if they are starting with solid blocks vs partially finished billets, etc. Only they can tell you that. But honestly if you've got all the CNC equipment, there's no reason to start with someone else's partially machined units.
