For people who don't know, American Defense MFG has released a new lineup of mounts. These are ones that lock into place, and don't require tools to adjust. Rumor has it that there are several other manufacturers who are getting ready to come into this market as well.

My question for you guys becomes this, what is it that you feel makes a good mount?

Light weight, durability, repeatability in zero, ease of use, ease of adjustment, no interference into the rail? I talk to different people and everyone seems to have a specific focus. Most people don't really appear to remove their mounts on a regular basis, but the guys that do seem to have a different list than those who don't.

What are your thoughts, and what are you looking for in new mounts?
