1) Are all PSA uppers (upper only - no barrel, handguard, BCG) the same, i.e., same material, same tolerances, quality, etc.?
2) I noticed the symbol (the one above and just behind the brass deflector) is different on some but not all uppers. What does it stand for - does it denote a difference in quality or material?
I ask this because I'm looking at their stuff and was about to purchase, but then I noticed that it looks like they have 2 or 3 "grades", specifically in there BCG's (for example: freedom, standard, premium - and then there's the nickel boron).
So anyway, I was just wanting to see if anyone could help. I'd prefer to know what I'm getting before I spend the money. TIA
