NEA in 7.62x39 - The Guinea Pig thread :)

Sorry, I meant barrel NUT. It wasn't tightened properly and had to tighten more one step.

My 'pardon?' still stands.

They're not really supposed to 'come loose'. It should have been a little more than 'hand-tight' to begin with :/

I'm correct that the barrel was factory installed......you didn't install it yourself?
 
Which range where you shooting at @ post #59? The RO allows you to shoot without "Eyes"?…..
I saw those NEA specials @ Target Sports and almost picked one up but decided to go with another brand.
 
It was factory installed. I know that it suppose to be tighter that it was ;)

its been one week since NEA shipped the extractor and no sign of it yet. I am giving them one more day before I start complaining.

in fairness...........if they shipped CanadaPost that could be part of the reason it's taking so long. Not necessarily NEA's fault.
 
Extractors are a weak point on x39 ARs. I was hoping NEA had fixed this with their bigger bolt. Clearly that isn't the case. I broke my second extractor on my custom built x39 upper a couple weeks ago. So I ordered 6 more from Brownells. They were back ordered so who knows when I'll see them. I'm starting to come to the conclusion that steel cased ammos is hard on them, but I suppose to definitively come to that conclusion I would have to spend a bunch of money on brass cased ammo, which kind of defeats the purpose of having the thing in the first place.

When I bought the upper the smith who built it sent a tuned recoil spring and an H2 buffer. I find that Norcy is the only cheap ammo that will reliably cycle this setup. To reliably run Czech ammo, of which I have a metric #### ton, I have to run a standard weight buffer.
 
!!!bolt failure!!!

Well, another bolt failure today. This time bolt itself. You can see at the video at about 40 sec something happened, I've noticed that something other than casing was ejected, I kept shooting and it ran fine after, except one FTF. Came back home, start cleaning it and voila!

I have to contact NEA again and let them now that I need the whole bolt now....

Sorry to hear of this. I was looking forward to getting a x39 AR, so I wanted this to work. This is not boding well.
I appreciate the testing and posting your doing in this thread.
 
I wonder if that had something to do with that extractor you put in since it wasn't a nea part. Maybe it binded and popped the lug next to it.

They have issues with there bolts period.
 
On the positive thing, Troy claymore is nice! Pushes all sound forward and it's actually gives the sound a bit more lower tone. Felt recoil a bit more pronounced, but I've compensated with ST-T2 heavy buffer and overall is really nice. Magpul M.A.D. lever also works fine and very useful. I really hope that LMT or superbolt will eliminate the problem. Not too impressed with NEA response so far. There is no phone number that I can use to call them, the replacement extractor shipped last Monday and no sight of it yet. Even with CP it takes no more than 2 days from Orilia to Richmond Hill.
