Which barrel nut wrench?

[DarthNul]

I'm building an AR-15 for CMP & NRA service rifle competition. I'm going to be using a Rock River DCM legal float tube.

The two barrel nut wrenches I have won't work with this float tube & nut. Anybody know which wrench will work with the RR setup?

If that isn't what you need:

Thanks for the reply Snyper!

The RR wrench looks just like one I have that won't work because the hole in the middle isn't big enough to go over the part of the nut that the tube screws onto. The hole needs to be almost up to the pins. I'll grind out the one I have before spending another $65 (plus shipping).

I messaged RR anyway but it takes them a few days to respond.
