Nope. The OP edited his thread because initially it started off with him saying NEA had done hard by him because his gun didn't work with a cheap mag. Everyone pointed out that you don't judge a gun based on a crappy magazine. He tried better mags and ammo, the problem persisted, and NEA replaced his upper. Not sure what the OP of this thread is trying to show by quoting that other thread?
The NEA issues, as far as I know baed on CGN, are as follows (in no particular order).
1) A dozen or so rails were accidentally installed and shipped which were out of square. NEA replaces them free if you are affected.
2) I've seen two posts where people complained that their chambers had reaming issues. In each case I know of, NEA shipped (overnight) the affected people new uppers at NEA's expense.
3) Some people don't like the greyish anodizing. Fair enough. If you prefer a darker AR, buy another brand.
4) I had one person pm me that their NEA upper had an out of spec top rail. Not sure what to make of this as the one I measured last week was fine and I've not heard of anyone else having a problem, but I heard of it, so it's posted here.
5) Some people complain of the "splotchy" barrel finish. Like the grey anodizing, the barrel finish is an NEA-unique process that leaves the barrels a very light grey colour. It's some sort of salt bath ferritic nitriding finish, not unlike the tennifer Rauch Tactical did on VZ's. I had a RT VZ and it was splotchy as well, though darker. The tennifer splotchiness was permanent, while the NEA splotchiness wiped off with an oily rag on the two barrels I've had. I think that the long-term performance of the NEA barrels is yet to be proven or dis-proven. For now I am happy with mine. Your mileage may vary, but NEA will likely NOT warranty your unhappiness with the colour of the barrel as they don;t view this as a defect and neither do I.
6) Heavy trigger/hammer springs. The first batch shipped with full-auto M16A2 spring sets. If you have a 12lb trigger pull, NEA apparently ships free lighter AR15 spring replacements to you.
7) Undersized gas port. I have no idea how widespread this is, but on the first dealer shipment some percentage of uppers had undersized gas ports that wern't picked up due to test firing with a can. NEA ships new uppers to you if you are affected.
9) Machining marks on the upper/lower/handguard or whatever. Frankly I've not seen pics of anything problematic, but I believe there are likely surfaces showing end mill swirls. Ever seen an LMT MRP or other billet gun? If not, then I suggest you go look at one. Every billet gun I have ever seen had this evident to one degree or another. It can be eliminated by slower feed rates and more frequent tool bit changes during manufacture, but that would increase price a fair bit. unless it's really bad, I would not consider this much of an issue personally. Your mileage may vary.
I think that covers the issues I know of. Most of these are confined to a single shipment of guns and have reportedly been corrected on subsequent production.
I found all these readily available in NEA's own posts except for the one issue I was pm'd about. I hardly consider that a coverup.
