I went from an M4s to a 4moa T-1.
I like everything about the T-1 better including the 4moa dot.
Pros:
- Objective size doesn't matter with both eyes open. I think the smaller sight offers a less cluttered field of view.
- lighter
- smaller
- 4moa dot makes a lot of sense with the trajectory of a 5.56
Cons:
- I'll have to buy two batteries instead of one in the next decade.
