Hi all.
I know that this question has probably been asked before, but I went through the search and couldn't find any answer directly pertained.
I'm in the process of building my second AR and I'd like to know if there is really any difference between the various manufactures out there concerning lower receivers. Now I know that a lot if not most of the outfits hang their name & logo on receivers made by someone else. But is there really any difference between them.
And I'm not interested in getting involved with a billet lower so let's not go there.
For example, there are T 6061 and T 7075 forgings. Is there a standard for this or are the 7075 only carried by the better names? Or is 7075 the standard.
We all know that certain name are "supposed" to be better, but are they? For example, I read recently that Andersons are just as good as the others but are cheaper because Anderson doesn't advertise as much and therefore has to sell for less.
It seems to me that what it comes down to is that all the pins fit the right way; not to tight and not too lose.
Opinions gentlemen...
Thanks to those that answer
