A standard armorer's wrench will not fit on a Aero Precision ar15 BAR barrel nut to float the barrel. The wrench I have is one from Ruger and the side with 3 pins, 2 are just alittle too close together and the third one hangs off the nut. I hear there is a 2 pin wrench out there but can not find it. Please let me know where I can get one. Otherwise,
I thought of belt sanding the 2 pins just enough to fit. It does not look like it would take much sanding to make it work. But I don't want to make it unsafe to use either. Torque on this nut would be 30--
35 ft lbs. Any suggestions appreciated. Aero does not sell a tool for this bar nut.Thanks.
 
I'd make one then.

BTW classmate of mine made a tool to work on his car (Honda won't sell the tool). He grabbed some scrap at work and said it took hours to machine this cheap tool. Turns out it was 4140 steel. Kinda expensive metal for a cheap tool.
 
The new Aero Precision "improved" receivers use a proprietary barrel nut and wrench. Call Aero if you need a wrench.
 
Seems I'm confused about which "BAR" is being discussed.
There's always the "Dremel and pipe wrench" solution.
