if you put tape over the mfg name you would be hard pressed to tell the difference. UNLESS it is one of the higher end billet or high quality finished ones. I have owned numerous lowers over the years and never was concerned with the mfg name, more so the cost to buy it.
Remember it is only a chassis like building a car. it is what's inside that counts. outside of the H,T,S moving all action and pressure is in the upper receiver (ok i forgot the buffer) Which depending on what caliber you run there are different buffers. I run an Adams Arms piston on my SBR, however i also have a heavier buffer for my 10.5" 9mm upper.
for the spouse i did a light weight build using a CAVARMS poly lower stock buffer 16" gov profile bbl and some trigger work.
take a look at then if you stop by friday..
