Broken Barrel Nut

[titsonritz]

Pictures to follow this evening.

So when I say “wrench” I mean the wrench attachment that has grooves to fit the barrel nut.

According to Aero Precision, this is a pretty common problem and it’s difficult to keep the torque wrench perfectly perpendicular.

The barrel nut is this one, with all teeth broken off.

That should be all you need to know about Aero. This kind of shit is SOP

Oh, yeah. I looked at the Aero site, but their pics didn't give me the idea it was that recessed. This one does:

Attachment 52410

May be able to tap it, but pipe wrench definitely not an option.

I am I missing something here? It looks to me that you should be able to remove 8 screws and remove that collar (it does look integral to me) on that POS "barrel nut" then use channel locks or even pipe to remove the barrel nut.
