RE: Standard Base or Dual Dovetail?
Quick release if you are EVER going to be flying or traveling with your firearm.
I've used both standard and DD mounts in the past. Honestly I like DD... I have had guns (Remington) that have not had the holes drilled/tapped straight, and if there is an issue, your scope will not seat flush in the rings... the standard one allows for windage, but its putting a bandaid on a bullet wound.
