Hey ,


just a heads up who anyone who recently purchased one of these BCG's from them in the last month or so.

I have tried mine out with some go/no go gauges i borrowed from triaq, the bolt will not close on the go gauge, however with the spare BCG i have, it will with ease.

I know from the now locked section of NEA, there were others who bought these BCG's. I wanted to let people know of potential issues stemming from using them without checking them.

Please check them out, cheers.
:wave:
 
I'm not familiar with these go/no go gauges, but if your bolt won't close on a "no go" gauge, isn't that a good thing?

Yes, but it says they won't close on the 'go' gauge ;)

Personally, I am shocked. Shocked, I tell you.

I'm thinking no... "the bolt will not close on the go gauge"

Beat me to it... Shocked, as in loose gas block shocked? Insanely-heavy trigger group shocked? Improperly staked BCG shocked? Problematic extension-tube shocked? Just shocked in general? :evil:
 
Thanks for the head's up JD. I don't think a lot of people have go/no-go gauges, and I doubt a lot of people would've necessarily even thought to check these. I mean, really - how often does someone have to run a go/no-go gauge on a DD, Spike's Tactical, etc. BCG... :rolleyes:

Dull-endmills/too-high-of-feed-rate/too-low-of-resolution-on-3d-milling kind of shocked

well given the level of problems with anything NEA, i was not about to fire my new build without checking any possibility of problems.

So have you decided what to use your paperweight for? ;)

Counting the days until one of these things spectacularly blows up from one of these defective parts...
 
so if it is not closing on a go then that means too little head space.... assuming of course the test was done correctly. what are the dangers of too little vs too much headspace...i get the bolt not being able to lock into battery part.

Oh and I am also shocked.

With an AR, with too little headspace, the bolt won't be able to rotate and lock up and when you pull the trigger.....nothing will happen since the firing pin won't be able to reach the bolt face.

Too much and it might run 'okay' but it will stretch brass, or you could get case failures, or if it's was ridiculously loose, the firing pin might not be able to reach the primer or you could get primers backing out.

There's probably some more things that could happen but those are some of the main ones.

You probably won't die, but it's not good for your gun.
 
Normally, a new assembly should close on a Go, and should not close on a No Go. Not unusual for a broken in rifle to close on a No Go (generally only .004" between Go and No Go - not whole lot). If the action closes on a No Go, then testing with a Field gauge is indicated. If it closes on Field, the rifle is seriously out of spec.
If the bolt won't close on a Go, headspace is below minimum. In a bolt action precision rifle, tight headspace can be a good thing. I like to feel the Go when I set up a bolt rifle. In an autoloader, failure to close on the Go is not a good thing. In a M-1, M-14 it is outright dangerous, because of the risk of out of battery firing. Don't know about ARs; but the bolt has to close cleanly for proper function. Jamming a round into the chamber isn't a good thing. At the very least, bad stoppages could result.
I recently obtained a NEA 18" barrel. I observed that with a near new LMT bolt, I could feel the Go gauge as the bolt closed. With a well used Colt bolt, the rifle accepted the Go, and not the No Go. Just as it should.

Well, too little headspace stops the bolt from closing. excessive headspace has to be very very excessive before it becomes a serious issue. At smaller amounts, excessive headspace can cause poor accuracy and reduced brass life up to the point of case failure after one resizing.
 
Excess headspace is significant when handloading. If cases are fired in a loose rifle, then FL sized, the possibility/probablility of case separations becomes very real. This can be a very bad thing, particularly if the separation occurs very close to the head. In some rifles, with unsupported caseheads projecting from the barrel, the consequences can be severe.

All sorts of ARs are put together from assorted pieces, mix and match. Usually gauges are not used. Might not be a bad idea to check.
 
How could something like this happen? They make parts for airplanes.

I mean really planes have to be built to spec no? I'm sorry I just don't see how you could in any way be telling truth. You are obviously making BS statements to slander NEA. I'm sure Jeff or Dave have sent you at least two emails threatening a lawsuit for slander by now. You should be ashamed. NEA is a perfect company with great public relations.
 
Way to beat a dead horse guys. I'm no fan of the way NEA runs their business ,but at some point it would be nice to see members, particularly the ones who should know better, give it a rest.
 
I'm running one of the new bcg in my NEA. Seems to work fine. Haven't tried that bcg in any other rifles, though.
