Viridian does an angled grip w/ integrated WL or WL+Visible Laser.
Not sure if you want the function or are trying to clone some specific build. But instinct tells me if you want something in that form factor not made of chinesium you’re probably SOL.
Printed is a good idea I neglected to mention that in my comment as an option. I’ve got a cloud defensive set-up on a gun that takes the equivalent of one 12 o’clock and one 9 o’clock mlok slot.
But I wouldn’t recommend using any laser or light from pre 2010 because doubtlessly someone(s) buying them to clone some obscure setup and they only ever made a limited production run.
