Once again a full blown pissing match has been started on a staking issue, who is right and who is wrong, a company that branched of from making aircraft parts to making firearms. The AR has been around for decades with a more or less a proven track record. NEA has put their twist on the AR that they feel is a improvement whether that is the case or not. It looks like most of the rifles made to date have gone to South Africa, correct me if I am wrong. My question is this are the QC concerns that are rearing there heads in Canada happening abroad. There does not seem to be to much complaining on the SA forums.
and here is a properly staked sabre, CMT, and RRA bolt carrier group
What criteria are you using to determine that this is "properly" staked?
I'm not sure if chisel staking is good enough or not but I do like that it is the best in showing if your bolts do start to back out. Actually a pretty smart system if it is sufficient mechanically. I'll leave that for someone more experienced than me to prove or disprove.
you can get that extra 25-35 in/ilbs of torque from more then one deformation method,
sure you can use methods to go beyond 80ish inchpounds to unscrew it, but you can over do it, deform the metal too much, or weaken the metal or screw too much.
or be this guy

So you are defining the method as "proper" if it increases the break-free torque by 25-35 inch pounds?
I would not define 'chisel' staking as correct, but thats just me.
There is a Bolt Carrier - and more importantly gas key shortage in the US.
Very few companies build 5.56mm Bolt Carriers - the majority are built by MicroBest, and there has been a run on parts due to the gun buying upsurge down here.
In the grand scheme - the staking of your gas key is minute at best - its user correctable, and I've had Colt and Diemaco carriers when I was in the CF, improperly staked that came loose, and created a Bolt Action gun.
NOTHING MADE BY MAN IS INFALIBLE.
Also - if you want to critique the gun industry - just compare the reliability of a firearm to a computer program...
when your iPhone crashes do you blow up the internet or send Apple hate mail?

the industry has their own numbers, staking is done to provide X amount of extra torque resistance, if you get X, your good.
you are welcome to have your own standards, why not weld those suckers in there, or design a new monolithic BCG that has one part there?
not to mention, the carrier in question is the EXCEPTION to the rule... most of neas are done side staked, I know mine is,
its kind of a moot point.
the OP's has been confirmed, by the manufacturer, as fine, despite the Internets personal preferences
like kevin said, other methods have failed too, you end up with a bolt action... not something that blows up.
NO its not the most common, but yes it does work when done right,
all these methods can fail if done wrong, all can work if done right
But what I am asking is "is the number you are personally using 25-35 inch pounds, or, if not, what information is leading you to conclude that the staking you described as proper is, in fact, proper.
I also feel inclined to point out the fact that while you quoted the part of Kevin's post that you liked, you did not include the part in which he said chisel staking is "not correct".
I don't disagree that it's not a huge deal, which is why I have always said, in every one of these threads in which I participated, that I would re-stake the key. Not that I would send it back, or demand a new one, or complain to anyone. Just that I would stake it myself, because, as the guy you just quoted pointed out, that method is not really particularly good.
