Anyone make better lens covers for the T2?

Are you talking about replacing the clear plastic on the flip covers? If so, i’ve debated replacing mine with some round glass microscope slide coverslips. The diameter of the clear plastic insert on the aimpoint covers is 18mm (if I recall) and 2mm thick, and the plastic insert just pops out with a little thumb pressure. I know they sell 18mm diameter circular glass for microscopes. And the glass needs to be flat/distortion free and usually claims anti fog properties. Thickness is probably close to 2mm, unsure of durability though.

If you’re looking for something entirely different, I know Armament technology makes a lot of stuff, never looked at their offerings though.

Crazy to think the current T2 caps are a significant upgrade from the T1 bikinis

I like the TangoDown IO covers.  You can’t see through them, but they won’t come off unintentionally unless you break them.
