Aside from these AAC shims, Have any of you guys found any narrow profile shims? I would like to just buy a bulk pack to have from Mcmaster Carr, Grainger, MSC but they tend to be 7/8 or larger diameter.

Gemtech shims also have a pretty low OD IIRC

The smaller-diameter shims tend to be destroyed when I try to time the brake.  I like the Precision Armament accu-washers.  They are 7/8" diameter, yes, but they are thick enough that they don't self-destruct.  You may need a thin wrench to install your brake.  Why do you need the small diameter shims?  Are you trying to hide the shims?  Having trouble installing them?  Don't like the washers self-destructing?

Gemtech shims have been my go to after experimenting with the cheap larger ones that like to deform under torque.

The reason I like the smaller shims is for lower diameter barrels. Nowadays its more common to have 5/8 threads on barrels that are .75 or even smaller. The larger shims end up all mangled in my experience.
