I thought I would throw up some pictures of my NEA-15. I know that some people here are wishing there were more pics and range reports...others are sitting on the fence in light of some of the QC issues..still others are considering cancelling their order. Take these pics for what they are worth and maybe they will help you decide one way or another.

First though, I will try and anticipate some questions and answer them ahead of time:
1) NEA-15 14.5" barrel with 12" rail. Received January 2012, second batch that was shipped out to SFRC
2)400 rounds, zero issues; 300 55gr AE .223, 100 62gr 5.56 PMC X-Tac.
3) I've had no QC problems. My gas key was staked, buffer tube was fine, second batch onward got new trigger group, etc.
4) If it wasn't for limitations imposed at my range I would have shot a heck of a lot more than 400 rounds by now:mad:
5) I don't have a range report because the few times I have had a chance to shoot this rifle (see #3 above) I have been having too much fun shooting to worry about videoing and documenting much more than my sh!t-eating grin.
6) the photographs below were taken in crappy fluorescent lighting so the colours may appear off depending on your monitor. Trust me the rifle is all black and the kool-aid is OD.
7) I didn't wipe down the BCG or anything else for the photos. A boresnake is all the cleaning this rifle has seen.
8) I am not a shill but it is no secret I love my NEA-15. My comments may be biased but hopefully the following photos are not.

I have the same *upper only*, got used and not sure what gen./production date it is. My only comment is that it seems to be a real good barrel, I'm getting some real nice groups even with bulk AE 55gr, under 2". Encouraged enough going to cook up some 69gr SMK's to try out.

My BCG must be from a different batch, see markings...

Nice! Thank You, I was starting to regret ordering one because of all the negative comments around the NEA-15's quality issues.

Perhaps an up close pic of the NEA will show how well it is staked, the pic the OP posted looks like it is not as well staked as it could be. (PC answer). I would prefer to see more material staked to ensure that the key won't rattle loose.

The rest of the rifle looks really nice. The upper and lower look great fit and finish wise. I really like that trigger guard and the look of the uppers lines.
 
^^ Good Post

I just looked at my Colt upper to compare to your post and it is staked much harder than the one from the OP. I don't like the LMT staking though, seems excessive.

Actually that picture there is "Counter Staking" and is in all respects far superior to the staking methods generally used. It's also considered to be excessive. Some like excessive. We don't counter stake, few do. But it is quite common in the aerospace manufacturing industry.
 
My appologies, I interpreted it as the original stake got loose, and they tightend it and restaked it again after. I didn't intend to mislead.

I posted the pics for reference, not to troll.

I dunno, maybe the screws tightened themselves after staking? :stirthepot2: (kidding!!!)

I didn't know staking was used anywhere else but guns... learn something new every day!

Many engine fasteners (internal) and dowel pins are staked as well to prevent them from backing off or worse binding with the other moving parts internal the engine.
 
Nice pics.

I have had no issues with my NEA either.

It may be a small thing, but I really am drawn to the War Griffon one the lower.


I have swapped uppers on my NEA lower with no issues at all, period.

My current fav is a lighter upper on the NEA lower, but I use my NEA BCG.

My current build will be based on another NEA complete lower. You just cannot beat the price for that package locally.

I thought you get a FA BCG. That is a SA BCG you have pictured there.

I noticed that too, but I didn't know they were marketed as FA BCG?

I personally don't think it makes a difference, the FA BCG is just heavier IIRC


Edit: after looking at the NEA website, it appears they do advertise M16 Full Auto BCG

Yeah I noticed that too. I asked NEA about it in another thread but they never explained this discrepancy. I didn't create a support ticket about it since functionally it is fine but it would have been nice to get the full auto BCG seeing as that is what was listed in the specs when I bought it.

The heavier weight of an M16 carrier is rather important in a short pistol barreled AR to achieve correct timing.

Many people have issues running short barrels 100% reliably. It all starts with a correctly sized gas port hole relative to barrel length, closely followed by carrier and buffer weight.
 
This is a Colt. Basically it is to ensure the screw is 100% tight. The stacking deforms so the socket head cap screw head cannot get loose.
