| Any pointers? Need to remove it for a KMR rail install. any special tools needed? |

When you remove the barrel from the upper, you'll see a snap ring on the back of the barrel nut/delta ring assembly - that's what holds the delta ring on. A pair of snap ring pliers, or fine tipped needle-nose pliers will let you remove the ring and then the delta ring and weld spring.
Cutting off a delta ring with a Dremel is possible, but I don't like the risks involved. Every time I've needed to remove a delta ring, I've removed the barrel first. |

If you're putting on a KMR, it has a proprietary barrel nut so you'll need to remove the standard barrel nut any way. remove barrel nut with proper barrel nut wrench, vice, and upper receiver block/clam shell/reaction rod etc...
If it's a factory assembled bcm upper that needs the barrel nut removed, good luck. I swear they tighten their barrel nuts to 150 ft/lbs. |

Don't cut anything, it all comes off as an assembly and will not be going back on. |
