This is the very first time I' ve heard of anyone having troubles with a Mighty Mite riser.

WWAG is right, we had troubles with the first run of Pro risers and it was fixed on the second run.

It sounds to me like the rest set up is causing the troubles. If you' re having to set the rest up where you can see the bottom 3/4 of the berger holes it should probably be lowered, nock point and all.

FWIW, I lined up one of our sight lowering brackets on a Mighty Mite and I also found that it barely hits the cables guard mount. It looks to me that I can shave just a hair off of the bracket with a Dremel tool to make it work fine. LMK if you want one and I' ll fix one up and send it to you.
