While I have no idea if I made the correct decision or not, because mine has only been in lockup for 30 days, I researched for about as long as my form 4 will likely take. My requirements sound pretty similar to yours and I ended up buying an AB raptor.
Its light weight and meets the definition of modularity for my use perfectly. It will work on every <=.308 rifle I own. If it works like I expect, I will buy another in .375 for the rest of the herd.
30 cal AB raptor 4 stack with a 4" 5/8x24 direct thread reflex mount and a 1/2x28 direct thread flush mount, a 30 cal cap, a 6.5 cap and a 223 cap.
It's short (4.7" from muzzle, if memory serves) and light and will be "hearing safe" on my 300 PRC down to 223.
I can only shoot one rifle at a time...
I know everyone here has their favorites based on their experience, and I have none. But, when it came down to it, I decided to buck convention for what seemed right for my use.
I hope I didnt F-up
