I am mounting a Dead Air flash hider, and put on a couple of shims to get the mount point indexed at 12 o'clock.
I then go to tighten it, and the shims are a larger diameter than the wrench flats, and can't get the wrench on to tighten it down... 
Any suggestions other than grinding flats into the shims? Anyone know if the AAC blackout flash hider tool will fit the DA flash hider? |

What type a wrench are you using? I didn't have issues with the a 3/4 crowsfoot.

Get a thin crows foot if you're using a torque wrench.
Otherwise just a thin wrench. Some armorer's wrenches are thin enough to work as well. |

What is that black band behind the shims with the writing on it?

I'd reduce the OD of those shims. Stick them on a 1/2 inch bolt and let them spin freely as you apply a grinder. A file to smooth out grinder marks and GTG.

Struck out finding a crows foot locally that's any thinner than what I already have....
I wish they had made the wrench flats just a little bit wider... |

Jam nut wrench or turn down the shims.

I've had the same issue before, I took a crows foot amd took a grinder to it. Ive used it twice since, once timing a muzzle brake with shims and another that had a large barrel diameter.

I used a Surefire shim kit. The shims have a smaller OD.
