Where can you come up with a Barrel Nut Wrench for the older Ambush with Round Holes in the Barrel Nut at 3-6-9-12 ?
I am trying to break one down for a friend and the barrel nut wrench for the:
Omega X / Modular Float Rail

2-Prong Barrel Nut Wrench
SKU: 16-033-08184-140 shows Discontinued.

I have called Daniel Defense twice and no one I have talked with seems to know about anything but the newer RIS II with Slots not Holes.

If it's the type of barrel nut I'm thinking of, this type of wrench below (circled part) will work.  Brownells sells these wrenches for $9:

Head on over to China freight and pick up a pin spanner.
Or to protect the threads, insert Allen set screws that are @ a 1/4" longer to stick out from the nut, and put nuts on those for a gripping point

Yes, this is the definition of Yankee engineering

I will order the barrel nut wrench from Brownell's next. I need to replace the single pin one that I broke anyway trying to get the nut loose.
