The type of Gunsight that the Ki-61/Ki-100 Series of IJAAF fighters were equipped with, and also the Ki-84, as I am setting up all my Jp planes the way I have my German planes with historical gunsights (which actually really help in the Ava!!!)

I believe there are some gun sight packs that have been done to the new MIL system that include Japanese gun sights.

thanks karnak, although the type 98II was an IJNAF sight, used on late model A6M's, N1K2 and J2M fighters, I am asking for army airforce sights

That gunsight pack has the Type 3 and Type 4 sights as well.  I am not sure, but those may be Army sights.
