Daniel Defense barrel nut

[punkerr1313]

I recently bought a daniel defense government barrel for my G&G as an upgrade because I didn't want the non-removable iron sight anymore. Upton trying to install it, I relized that the barrel needs a special barrel nut that has a wider opening. Now I have a barrel sitting around that I can't attach to my gun. Is there any way anybody can help? Modifications or suggestions, anyone selling a daniel defense barrel nut, anything would help. Thanks guys.

It's called a delta ring 

Do you have  a ris/ras  ?

My gun doesn't have a hanguard it has a ras, the one that comes with the gun.

okay, does your outer barrel look like this?  http://www.evike.com/product_info.php?cPath=25_101_277&products_id=28992

 cause this kind of barrel fits into your upper reciever and a delta ring is typically screwed on over it to keep it in place.
if this is the kind of barrel you have, then maybe we can talk
