remove the barrel and take it off?
Honestly.Honestly?...Just cut it off. D-rings are cheaper to buy and replace, than the tools required to remove them.
Yes, to install a Troy FF rail. Thanks for the links and advice everyone.Why are you taking the upper apart? Is it to install a free float rail?
I've heard of people cutting the delta ring off so they don't have to remove the barrel on some brands.
But to answer the original question. The only way to remove the delta ring, other than removing the barrel, is to cut it off. There is no special tool
When Enfields were "Converted" to hunting rifles, they used to cut off the rear handguard retaining ring. Guess what the hardest part to find is when you want to restore an Enfield is? Just saying. It always to do the job the right way then the fast way!

Meh you can call it the "right way" but I'll do it the way that makes sense and is appropriate for my needs. If you're putting a free float rail like the troy on and intend to keep it on then just cut it off. It saves you from beating the piss out of the FSB pins, removing the FSB, etc. It'll save you time and grief and it will not in any way effect the function of your rifle.
Sounds like what buba said in 1953 when he cut down his daddy's .303, you know the one with the heavy brass scope on it!
