to see the video, go the the second page of the ar forums and down at the bottom youll see a thread called "cutting off delta ring"
its on the seond page. . .
im too lazy to post a link
"hard" is a relative term. I don't personally own or have those rails, but I think the delta ring still needs to come off. If it does, you don't need to take the whole barrel assembly apart, you can just dremel the delta ring off. I myself would rather take the assembly apart and salvage the ring.
Would these be a step up?
