Good to know about shims...

We found this in a Bushnell box not to long ago.

Seems like it would put undue stress on the tube. Wonder how old that chart is?

Not old and it doesn't stress the tube. Leupold and Swarovski used to have the same guide I am not sure if they actually put it in the box but you could get a shim kit from Leupold that had this in the lid.

Thanks Skylar

Your welcome.
