Rell,
AHR have a QD mount for a red dot sight (C-more & Leupold) got it as a back up / different competition loads for my .404Jeffery.
I used the C-more one because you don't need to remove the whole sight to change the battery
I have my loads worked out now so will dial it in next time at the range.
Nice rig
Cheers
