Another " My first AR Build " thread.. (Cadex meets Vltor)

To be honest, i was really frustrated while assembling a lower with a NEA parts

Are you sure that it wasn't the lower that was out? Not saying that it couldn't have been the parts kit, just it wouldn't be unheard of for it to be the lower.
 
Nice build. I'm not a big fan of the older Magpul M93 stock, but each to their own (you might want to check out the new Magpul STR or ACS-L stock if you're looking for something different). Your problems with your lower are almost certainly the LPK; I'd suggest something like a Stag, Daniel Defense or RRA next time (you can't really go wrong with any of those).

not a chance, the cadex lower is perfection, i have put a few togeather, they were the easyest to do of all of the brans out there.
But i have used some of the dpms lower parts kits and NEA, they look the same and have the same issue.
The roll pins are crap. the parts are rough.
Many years ago i fround out the value of a good lower parts kit.
The armalite and DD kits are what i try to use, RRA after that.
The rest are just repackaged made in Teiwan products.

Love the M93.. best stock i ever had, the fact that cheek rest always stays in the same position... is great. Plus, with NEA barrel you need something heavier to balance out the weight.
I will definitely look into a different LPK..
 
What should i do with a gasblock? should i just force it on and ruin the finish on the barrel..? And can someone please tell me who has a carbine length gas tubes in stock..

We've gone through several hundred parts kits and not seen any of this. Is it more likely that several different parts all manufactured at different times in parts kit are out of spec, or one lower is?

We'd be happy to send replacement parts should the OP wish to post his findings. ;)

You'll be happy to know then that our parts kits are supplied and are the very same used as one of the companies named above.. (PS, it's not DPMS).

I will take your experience as a glowing reccomendation then. ;)


.. I suppose the problem with not naming your suppliers is people assuming they're widdled out of rock in some third world country.

Let's assume that since we use full auto parts kits that are well priced that they must me made in sufficient quantity to garner that price. How many foreign Select-fire AR manufacturers are there? I'm pretty sure you can see that they're not Norc, Bushmaster or DPMS. Blame the parts if you wish, we'll send replacements; but I guarentee that if we revealed the source and who uses them there'd be a pile of people eating their hats and back-peddling to defend their true loves.

Our barrels are exactly .750 at the gas block. They don't have an exterior addition finish, rather a surface processing. Most companies undersize components to be compatible after plating (we do on all of our parkerized components). If the finish on the gas block is a little thick, it will fit tight. Try a little scotch brite inside to smooth it out. A touch of oil won't hurt either.

The barrel is harder than the gas block. As long as you don't smash it on, the barrel should be ok.


While we've had some past issues with some components, the issues expressed above haven't been one of them.

The only parts kit issue I've seen is someone trying to install them into a colt small pin lower. (Go figure)

I went with a Magpul UBR on my HK to balance the weight aspect as well, so I can certainly appreciate that (incidentally, the UBR was the replacement for the M93). I've removed the storage panels and replaced the stock pad on mine.

Instead of replacing the entire LPK you could also look at a set of KNS anti-rotation pins (I'm particularly fond of these). I might have a spare magazine release button, so if that's all you need fire me a PM and I'll send it out.

If you're considering a different pistol grip you might want to check out the MOE+. I have the CAA on my PDW (and love it, btw), but the rubberized texture is a big plus. Good luck with the rest of the project!

Could be the lower having an allergic reaction to the third world parts :D
 
Maybe they're allergic to proper military Select-Fire parts kits, and prefer the more traditional paper-punching variety. ;)

When we buy them from the third world we'll let you know so at least the rumors can be accurate.

OP; if you would like a replacement kit sent on the house, let me know.

Dont you mean .750?
a tight gas block is not a bad thing so keep it if you can.
we installed one of ours on a 7icn bbls yesterday it was very tight.


Edit* not an NEA 7"bbl and other brand.

All the ones we've done with Daniel Defense LPK's fit perfectly. DD has certainly punched a lot of paper though.
