Removing delta ring

[lazareth1]

Hi guys,

I'm completely removing the body of the KM4S M4 rifle and I'm stuck on the delta ring. The outside of it is loose so I can't unscrew it! Is there a good way to get these off without buying a delta ring removal tool? :\

Crap sorry I just realised that my old thread is still active.

Can an admin remove this topic please?

Thanks!
