Hi all. I am really hoping not to get flamed, as this is a genuine question.....

I have a complete NEA AR rifle - upper, lower, barrel, stock, internals and so on are all NEA. Bought new from a site sponsor.
Is it just my rifle, or does nothing MilSPec fit NEA rifles? I bought a Magpul CTR stock. Doesn't fit NEA, but fits all my other AR's fine. Same with internal parts (other than springs, of course - I had to replace the springs, as it originally worked as single shot only).
Does NEA build their rifles to commercial spec, which I understand is different from MilSPec, or did I just get an odd rifle?
Would love to hear from other NEA owners, or perhaps NEA themselves.
Thanks!
 
buffer tube and stock are the only two items that has two separate specs and yes NEA uses a commercial buffer tube so does a lot of other companies, otherwise everything else on the NEA is within the Mil spec range.

What internal parts don't fit exactly? If it's a brand new gun that needs new springs ??? and has internal parts that don't fit why not just send it back to the site sponsor you bought it from?

NEA uses commercial buffer tube. I suspect your CTR stock was for a milspec tube.

I don't think NEA has used commercial buffer tubes for years. Perhaps Ryan can chime in and let us know when they switched to milspec tubes but I'm pretty sure it was at least 3 years ago or more.

7.5 inch 556.. will not extract reliably and a few popped out primers.. any idea what the issue is? I've read the spring may be to weak now allowing the bolt to blow back before the casing has time to reshrink after firing etc.. anyone else have this problem.. using brass cased norinco

I owned the same carbine that you have and encountered similar issues. My carbine was heavily over-gassed from the factory, to the extent that extraction was overly violent with the extractor frequently slipping off the cartridge rims rather than extracting. I noted that the extractor spring was the old, basic design without the elastomer plug insert so I upgraded the spring set with an extra strength kit. That sorted most of the FTEs, but the ejected casings still showed signs of violent, premature extraction (stretched rims) and perceived recoil was still excessive. Rather than using a heavier buffer to slow the BCG, I elected to treat the problem as close as possible to the source and instead installed an Adjustable Gas Block.

Once I had that gas setting properly balanced that little carbine settled right down and ran like a top. Reliability improved to 100% and the perceived recoil dropped off to less than I actually expected. That was the added bonus of having a properly balanced gas system, whereas many apparently come over-gassed from the factory for reliability reasons. Anyhow, those are a couple of fixes that will almost cerrainly sort out your extraction issue. I'm not so certain that either will help with your blown primers however. Perhaps someone with more knowledge of overpressure problems in ARs will step in and add their $.02

Best of luck sorting your problem!

All three of my nea rifles have mil spec tubes. I did have a issue with some fitment of lower parts in a striped nea lower once can't remember what it was.

Awesome glad I'm not the only 1 lol. Can I ask where you got the gas block. This is the first ar style rifle I've owned and expected more.. and the primer i only noticed on 1 casing that didnt extract i should have looked closer but got tired of dealing with it and went back to my t97
 
You can get the adjustable gas blocks from just about any site sponsor that deals in AR parts. True North Arms likely have the least expensive examples and to be honest not much seems to separate the cheaper models from the "big name brands". Something like this ought to work on your NEA carbine:

TNA offers $7 flat-rate shipping which is a bargain compared to most. Good Luck!
 
If you did 5 minutes of reading in this forum you would have gotten the answer to steer clear of nea products. A thread like this one pops up every other week. Either it doesn't run or stuff doesn't fit it.

To answer your question yes it's fairly common. Your best bet would be dump it and get an ar made by a decent manufacturer.
 
I have a NEA lower on one of mine, no issues and works great.
I know of several NEA's running regularly with no apparent issues.
Not that I see a ton of them, or others, but the ones I've encountered seem to work.
 
Just checked. The oldest safe queen NEA I kept as a loaner rifle has a commercial tube. The later gen a mil spec. Both were factory rifles as far as I know. Go figure.
