Quality Armorer's wrench

[Cosmoline]

I am in need of a quality Armorer's wrench for an M4 carbine. I have seen alot of them at gun shows and honestly they dont all look that great. Maybe I am being too critical but I would like something machined and not just cast and thrown into a box for $30. I have researched a few online but its tuff to determine what is good. Any recommendations would be geatly appreciated.

My buddy designed an Armorer's wrench, but it has yet to be produced. To do it just right, it had to be EDM'd and that drove the unit cost through the roof. The teeth for the barrel nut part of the wrench is the ball buster.

Really the only part of the armorer wrench I use is the barrel nut part. Everything else has a specialty tool dedicated to it. I can't remember which one I run, but it's been just fine for building ARs.
