Do we need to get into all the bolt failures that have shown up here on NEA rifles? Sure, let's do that. I'll add my comments in bold and you feel free to provide some proof to what you're claiming.
the bolt carriers with holes in the wrong place I don't recall a single carrier with holes in the wrong place let alone multiple "carriers" as you state, please provide examples,
gas keys falling off rifles Again, I don't recall a gas key falling off a rifle, let alone multiple examples as you contend, please provide examples,
gas keys with angle grinder marks on them I recall one example of this, it was an abomination.
un staked gas keys Saw a few pics of those I think, some poorly staked ones as well,
bolts broken straight through the cam pin hole, broken cam pins, over sized firing pin holes lugs broken off after three shots All attributed to a rifles assembled over a period of a few months a year and a half ago where NEA (and others) received a bad run of bolts from a supplier. Since then they've been making their own without issue,
I have seen your own rifle with gas key mis alignment You saw pictures I posted of my own rifle with over 10,000 rounds through it, the nub on the gas tube was worn, and you conclude from the picture the gas key is misaligned. Like every one of your criticisms, it's based on pictures you've seen on the Internet, no first hand knowledge. Sorry to burst your bubble but a) my gas key is not misaligned and b) my BCG is a dpms, a fact that is clearly stated in the very post you are referring to. If you didn't have blood welling up in your eyes every time you see the letters NEA, you might have read that.
