NEA-15 12.5” Carbine


Disclaimer: I am the majority shareholder in a business which recently sold services to North Eastern Arms Group. This happened very recently; between the time they shipped it and the time it arrived, we ended up setting up a deal which leaves me not entirely independent of their organization.

Consequently I would like everybody reading this to be aware that I am no longer the disinterested third party I used to be.

NEAG is not the only organization my company deals with, however, the nature of NEAG’s involvement with past posters who wrote about their products is such that I think it is important for me to point out: they have recently agreed to pay my company money in exchange for services not related to this testing and evaluation.

As I said elsewhere, in some ways I’m a little disappointed that it worked out this way; I was really looking forward to running the gun hard, reporting the findings, and hopefully giving everyone a very detailed look at the gun and its advantages and disadvantages.

I am still going to do that, but I accept that my opinion on the gun will be worth less than it was two weeks ago. I anticipate that some people will probably accuse me of altering the review to favour the NEAG gun. I won’t do that, but I can understand people who would voice that concern. I think it’s fairly reasonable. If someone from the E. A. Morris Institute of Oncology advised me that cancer concerns regarding cigarettes had recently been shown to be greatly overblown, I would obviously be a little skeptical.

So please bear in mind as you read about the gun: I do have a financial interest in NEA remaining in business for at least as long as it takes for them to pay out my company. Not that I thought this review would significantly alter their outlook...but anyway, that’s how it is.


Arrival and Initial Inspection

The gun showed up on a Thursday, but I was tied up with work all weekend. I gave it a quick field strip and had a look at the bolt carrier group. Staking is good. Carrier finish is good. Internals overall...looks fine. I had gotten a pretty thorough list of questions from Westicle, actually - he’s quite knowledgeable about the platform - and started looking through the gun.

Without rehashing an entire list of specs, basically, we’re good to go. Extractor spring looks standard, with a black insert. No O-ring, but then whether that’s a good or a bad thing depends on the build. In NEA’s case, they’ve found that running O-rings on their carbine-length guns decreases the reliability as the extractor spring ends up overpowered. I’ve seen that a few times and don’t find it all that surprising.

The quality of the machining has definitely improved from the early guns. My lower is a bit rough but it’s early, and it would have been scrapped if I hadn’t insisted on that specific serial number months and months ago. The guys at NEA tried to talk me out of taking it, but I wouldn’t budge. I don’t care that it’s a bit ugly. I’ll just get another lower from them later on if it ever becomes an issue. In fact, I’ll probably do that just so I can take better pictures without everyone panicking about the tool marks on the lower. If you notice them in pictures, just remember: this would never make it out the door today and they tried to stop me from taking it.

Aside from the lower, it looks good. Surfaces look nice. I know they’re treating them differently now; frankly I don’t recall if they’re keeping their approach to surface treatment a secret or not, but it’s much better than it used to be for sure. All the critical dimensions are clearly done properly. Really it’s just the outer surfaces of the lower that would be of any concern to a buyer, and you won’t see another like this one.

Bottom line: looked through the gun, didn’t see anything that worried me particularly (although I am a shooter, not a gunsmith) so I slapped an Aimpoint micro and Daniel Defense mount on it, wrapped it in a VCAS Medic sling I had kicking around, snapped a couple of pictures on my deck, which should fairly obviously reveal my location as Vancouver, and set it aside for the next range trip.

Range Trip Number 1

Temperature 7 degrees. Light rain. Covered shooting area.

Loaded up 4 Fusil GI-type mags and 6 Magpul PMags. Not much to say from here on out other than give numbers.

Rounds: 370 (mags loaded + 3x100 boxes AE bulk, 1 box PMC)

Stoppages: 0
Malfunctions: 0
Breakages: 0


I was not really in an environment conducive to precision; consequently I can’t tell you any details about the accuracy. Certainly there were no obvious issues with the accuracy of the gun; at 100m the impacts were absolutely predictable, so it’s not shooting giant groups, but whether it’s a 1 MOA gun or a 2 MOA gun, I have no idea. It feels tight and smooth. The gas port is almost certainly quite a bit smaller than a TDP-spec gun. I don’t cycle through tons of ARs, but I would compare this gun to a 16” with a carbine-length system in terms of recoil impulse. It’s quite tame. I was very glad to see it run well for the day. Ejection was consistent; 1-2 o’clock and 2m ahead of me, no exceptions.

When I got home, I popped it apart and snapped a few pictures. I tried to hit the thing with light from a couple of angles to give a bit of a look at the internals, but to be honest I am pretty tight for time today and can’t really afford the amount of work to set up a really good photo session. Fortunately I type very quickly, or this write up would not be happening just now.

The nitrided surfaces sure clean easily. I will probably give the internals a cleaning just because it’s new, and I might as well let it break in properly. At this point I’ve just given the bolt a quick wipe down. It was during the bolt cleaning process that I noticed the one unusual thing: the firing pin retaining pin was bent. The NEA-15 uses an M16-type firing pin, and the spool on the pin is clearly striking the retaining pin. Some contact is not a big concern but if the retaining pin is a little soft, well, over time that will generate an issue. It’s a two-cent part and they’re offered to send me a new one, so I’ll see if it does the same thing. Jeff tells me it’s the first time he’s seen that. It’s not really severe - if you’ve ever seen the combination of hooked M16 hammer and SA bolt carrier and what that does to the retaining pin, that’s much worse! Anyway the one they’re sending is from their current batch of parts, just in case I somehow ended up with an old stock pin from one of their previous suppliers. I’ll probably run this one for a thousand rounds and see what kind of shape it’s in, then switch and see what kind of beating the new one takes. I’ll let everyone know how that turns out. For the record bent retaining pins aren’t unheard of, so this isn’t an “NEA only” issue. The cause is usually sporter-style bolt carriers, but soft pins are pretty common also. The original design called for a slotted solid pin, which was eventually dropped because of manufacturing cost. Anyway, that’s the only thing I’ve seen so far that’s caused either of my eyebrows to raise.

And now, on with our pictures:

I don't have pictures yet - I'm planning to photo the internals and let them sit for a week or two before cleaning it to see how slippery the ARC+ stuff really is...if it's really slick the carbon ought to wipe right off, failzero style. We'll see about that.

Anyway I figured an update is in order even if the photos are not available yet.

Don't get used to this pace - I'm paying full retail for ammo and so far my business expenses exceed my income slightly...this kind of testing isn't cheap and it isn't helping! But anyway, I did dump more ammo through it.

Again, I took 10 mags to the range, which makes it really easy to track ammo usage.

Today's session: 350 rounds. No problems. I'll keep a bolded running tally, I guess.

Rounds: 720

Stoppages: 0
Malfunctions: 0
Breakages: 0



One thing that did crop up...I had one PMag which failed to lock back on one round, and another PMag which in one instance did not drop free. I'm not sure what that's about. I've made a note of which mag did what, so I can track that in the future and hopefully figure out what the story is. In most cases I would tend to assume that these are mag problems, not gun problems. That may well be the case here but I will keep track of what's happening and let everyone know how things develop. Those PMags are both quite new so that was a little surprising. On the other hand, frankly I hate running pinned mags and diagnosing "probably the mag" type issues. In particular mags that don't drop free or don't lock back...very hard to know if the issues would occur if there wasn't a god damn rivet in there. Still, that's life for the time being.

While I don't want to do any cleaning for the next week at least, just to see if the carbon will actually wipe right off (as some claim is possible with some types of nitriding) I did pull the bolt carrier just so I could get a look at that firing pin retaining pin that was worrying me last week.

There's not much to add, though...looks exactly the same. The bending is not severe, as I can pull the thing out with my fingers, and so far it's not getting any worse. I think it's possible this gun could do with an H-buffer. I definitely would still not describe it as "overgassed" - it's incredibly smooth for a 12.5", and the ejection is absolutely consistent. But if it can be correctly gassed and "underbuffered" I might guess that. It's definitely not by much, if at all. I'm speculating wildly at this point but we'll see what it does with a new retaining pin, whenever that shows up. If it does the same thing, I'll get NEA to send me a heavier buffer to slow it down a little and keep the FP from whacking that retaining pin too hard. Although at the moment I'm inclined to run it until the pin breaks, just to see how long it will go.

I also have a fair amount of information to suggest that the retaining pin is a one-off softy...they're running these guns as demos with suppressors on them and haven't run in to issues with this pin, and if the suppressors aren't generating similar issues then I'm guessing this is not anything to worry about.

Anyway, as I am inclined to say about most future events: we'll see, I guess.


I'll try to get some photos up for everyone Wednesday, which is probably the next chance I'll have to do much on this.

Thanks for starting this thread.

I've quoted two of your photographs. They illustrate something I have not seen before, related to the method used to machine the magazine well. It appears as if the well is machined by drilling four corner holes, and then milling way the balance of the material. Each corner of the magazine well shows the remains of the hole. Other makers use a broach, and the corners of the magazines well are square, not recessed and radiused.

Observe how thin the material is, from the hole to the exterior sidewall of the receiver. It appears as if there is very little metal left, particularly at the rear of the magazine well.

Is there a generation number to the NEAs?
Officially no; however I think dealers would generally support the idea that there have been 3 or 4 iterations, as they changed out suppliers and got better at building the guns.

Ryan of SFRC might have thoughts on that...he has handled far more than I have and I think has been an NEA dealer from the get-go. I know the guys at NEA speak highly of him.
 
Looking forward to following this. Was looking forward to a non partial review, at least you disclaimed your relationship. Still going to get the haters fired up! Guess you reserved the first 6 posts so we don't have to read through that again.

Get at er that's a hey of a pile of rounds!

It is definitely not overly thick. The thinnest section is 0.040".
 
I have a NEA with a serial # in the low 200's.

There were a few growing pains, but with a little elbow grease and under $100 of my money, it appears to be a solid gun.

Current round count is 1800-1900, just shy of 2K. I have yet to clean the rifle :D

If I get a mo in a bit I will dig out the calipers and measure the area tiriaq pointed out...... I never noticed that it was narrow in that area on mine, but then I wasn't really looking at that particular part of the firearm.

Cheers!

Edit;

I had to check.......

My NEA is .039
My Armalite is .091
My Dlask is .081
 
nice review... glad you like it

the mag well on mine is .064 at the thinnest cut, but it is tapered, and gets thicker closer to the bottom .132

I really dont see that point taking a lot of stress, so I am really not concerned, I actually prefer the minimum of material on it, since weight is second only to reliability and accuracy for me

going to pass 4k on it this week too since I have another practice and a 3gun on Saturday,

mine is sub 300 seriall # for those interested
