King Arms barrel nut/delta ring removal

So I just bought a received my new King Arms M4 a few days ago. My lovely Larue rail is awaiting install, but I can not for the life of me remove the barrel nut.

I don't have an armorers tool, I've just been wrapping a cloth around the spikes and using channel lock pliers. I've even tried heating it first, to absolutely no avail.

Any tips?

You should really use a delta ring / butt stock wrench... Using pliers will mostly damage your delta ring or yourlself... (been there, done that...)

I have used the pliers on my (leather man\multi-tool) to get mine off!its works ,but you might need a thin cloth so you don't scratch the paint!

The KA delta ring is on insanely tight. If you you buy the delta nut wrench make sure it is a good one.

On my particular king arms m4, the spacers for the ring were bent into the threads making it impossible to take off without stripping all the threads. If you don't need the delta ring, then you can just dremmel it off. That's what I did.

1. Be careful...receivers aren't all that strong and it's entirely possible to crack them
2. It's likely seized...and I'd rather cut a delta ring off than risk breaking a nice receiver
3. If soaking it with a penetrating lubricant doesn't help...then it's likely not much else will
4. You need a bit of leverage...assuming you aren't using smurf sized pliers. Also, squeezing it isn't really helping.
5. A good armorers wrench is really handy. Find a good local gun doc...he'll have one.

best of luck

Never put a screwdriver as a lever in the pin hole, I slightly broke my receiver because of this and was lucky that I was able to fix it.... Dumb idea. A useless ring doesnt worth it, Listen to M102404 advice cut it if it wont move!

I'm inclined to agree with Ghostnote. On my ka m4 the delta ring wouldn't budge even with an armorer's wrench. I say cut it off.

I'm going to piggyback on that thread real quick as I have somewhat related issue:

I own a King Arms M4 as well, that came with the Larue RAS (7")
I've been trying for the life of me to unscrew the flash hider and never achieve to make it even a little. I did try to soak it in hot water before hands, didn't help.
Even decided to use Vise-Grips+Towel, and all it did is what you'd think: scratch the flash hider :P

I'm starting to think it's not removable, in which case I'm not sure how I would be supposed to be able to change my upper/barrel (can't slide RAS far enough because it stucks on the gas-block which is blocked by the hider... get it?)

Any thoughts?

Thanks

Some models have their flashhiders glued on (i.e. epoxy/superglue)...or loctite'd on. Either way, usually hitting it with a propane torch will vaporize/soften the glue enough so that you can wrench it off.

Most flashhiders have flats where you're supposed to use a wrench....

And you've got to hold the outer barrel too (better than holding the receiver...for AS)...if you need additional grip, sometimes a bit of rubber sheet will provide enough grip for your vise/pliers while still protecting your barrel.

If the flashhider is truely mangled...then have at it I suppose.

if you plan to do external work on your gun, best you invest in an armorers wrench IMO

hehe King Arms makes a Larue you know kekeke

Listen to these guys, get an armorers wrench or take it to someone who has one or your more then likely going to break or ruin your receiver or the delta ring.

MP, just to make sure, a lot of Flashhiders are CCW, hope you took that in consideration, beside the little hex screw that might be locking it in place !!

Yup I first tried unscrewing CCW (well, clockwise to unscrew right? unless I got it wrong all along hehe :P) but when I saw it wouldn't budge I did try CCW. Also, I couldn't locate any grub screws or anything, which would lead me to believe more and more in the "glued" theory
