Optic for Amutorch / Ochoos AT40?

I have two AT40 lights. I like them well enough, but I now want to convert one to more of a thrower (I simply have too many super floody lights, and I need something with more of a balance or maybe more towards the throwier end—maybe like a Fenix PD25 for example).

Which optics are available for this light?
