QD are good for a back up scope or to have a higher power scope for load work and lower to hunt with. On a heavy rifle they just seem right but I would not be likely to take the scope off to use irons in the field unless the scope got banged. The tally peep is a nice addition and can be carried at all times. You can increase the aperture size to make it more of a ghost ring. I have also had good reputability with the fixed Talley's and they are fast to change with the Torx screws. On some rifles I took the levers off to make them more snag proof and a 100% reliable.

"When you disarm the people, you commence to offend them and show that you distrust them either through cowardice or lack of confidence, and both of these opinions generate hatred." Niccolo Machiavelli
