KRG Bravo question

[H80Hunter]

Any ideas on how to set the KRG Bravo adjustable comb to the same height each time? I realize this isn’t rocket science, I got it where I want it and found an appropriate spacer so I could easily reset it to that height (and wrote down the gap measurement).

Again, not that that doesn’t work, but any clever ideas on a spacer or standoff so it’s always the EXACT same?

I cut a couple sections of aluminum arrow for spacers that allowed it to drop in to the same spot each time.

Rifle case cut down, .223 might do it.
