Finally received my NEA PDW *edited with range experience*

i was thinking the same thing... i wonder if running it with a PWS CQB Diablo or a Noveske Pig would help increase pressure, and in turn cycle the rounds properly...

I run a PWS CQB on mine and I've never had any problems with it, but I'm also running a different setup. I'm running either the Spike's ST-T2 heavy or Enidine hydraulic buffer on mine.

Gas port size and buffer weight are two ways of tuning the AR.

but then that has nothing to do with tuning but all to do with wise selection of parts.

an incorrect sized gas port is only relevant to an inadequate manufacturer and the choice of an incorrect buffer is up to the person whom assembled the rifle.

Aside from the trigger, there really isn't any tuning on an AR (unlike a 1911). You assemble with in-spec parts that are correct for the intended purpose, or you don't. The latter will obviously lead to problems.

You say tune, I say "upgrade"... ;) There are a lot of modifications you can make (too numerous to mention) to adjust performance, such as the trigger, buffer, flash hider, BCG, charging handle - just to name a few.

Like pbr, I was just curious about the flash hider he was using.
 
I would think that the NEA 7.5 would come stock wht at least a .063" gas port, but the optimal would be around .067"... i can't find any specs of this on thier site...anyone else out there know?

my guess would also be that NEA designed the 7.5 for use with a suppressor as alot of the rifles they are making are going to South Africa, New Zealand, and many other countries where suppressors are not only legal but possibly mandatory. if that is the case, then they probably wont come with an enlarged gas port...
 
A2 Cage. I had FTE with both types of ammo, which I shouldn't have to worry about. Beacause if I were going to take this with me, it would need to be able to feed all sorts of rounds.

next time I'll run it really wet...just to see...

I don't think I should need to change any buffer tube or sping or gas port or anything, I would think it should come from the manuf ready to go, or at least a list of recommemded ammunition.

in anycase tmrw I will consult with my retailer first.
 
Lots of speculation here...

Of course thje gas ports are larger than any other barrel. Shorter the barrel, larger the port.

If you have specific questions or troubleshooting issues, bring it to our board.
 
To be fair to NEA, I have a buddy with a PWS Diablo 10.5 barrel (I think that is the length) He had to switch out to a heavier buffer to get the carbine to cycle properly. (Luckily for him he had a SR-15 to fall back on. LOL) It would seem that finicky-ness is inversely proportional to the barrel length.

Add the fact that they are mass producing stuff for markets with an with out suppressors and I can see there will be further growing pains. I am sure they will help out all the purchasers of these rifles and eventually get their designs correct (muzzle devices, buffers, gas ports etc) to work for our market as well as SA.
 
Have you checked the extractor yet? IMO if your having extractor issues with various magazines and various ammo... start by inspecting your bolt , specifically the extractor. Check the extractor spring and check to make sure the buffer (rubber thing) is in there.

I would start with the simple stuff and work my way back to replacing buffers and etc.

It's a new rifle I would hope that this stuff was already in the gun!

Yup!

But sometimes people disassemble their guns prior to the range. If he field stripped the bolt and dropped the extractor booster (rubber nub) he might not have noticed (it is sooo small).

Then again maybe he didn't touch it at all, but it is still the first thing I would check now that the OP ruled out magazines.

I am just trying to offer a possible solution, not slag NEA or the op.
 
I haven't had a chance to detail strip the gun after my range trip. I'm going to start a new thread on the NEA forum regarding my FTE issue.
