Master-Fit® Armorer's Crowfoot Wrench Heads

I recently purchased the 30mm crows foot wrench for a free floating barrel nut. I selected this brand because it appeared to be manufactured for more strength against spread and subsequent nut rounding by having more mass of steel surrounding the nut opening than other brands of crows foot wrench heads I looked at. In this regard I got what I was looking for and it's a true 5 star tool.
As much as I appreciate the quality of the tool, the wrench head is actually just a touch too beefy. The barrel nut I needed to torque is from Wilson Combat (pn# TR-Trim-Nut for reference). The thickness of this wrench head was slightly too thick to fit on the nut flats. The wrench head mic's out at .45" thick, and I had to machine it down to .38" in order to get the proper fit. After that it worked as it was supposed to with no sign of spread or slippage. It's just frustrating and inconvenient to pay a premium on the tool and then have to immediately modify it in order to use it.

Like a hand in a glove. Maybe even better

Exactly the one thing I needed that the other armorer's tools I have didn't provide.
