I have a little problem. When I first logged on with the TU2S I changed the gunsight to another one, not knowing there was no options for the defensive guns, and so now I cant select a gunsight that will work for all the guns. Basically heres what Im looking at.
The pilots gun.

And the sight I keep getting for the gunners position.

Basically what I get is 4 little ridges at the top of what should be the gunsight and I cant figure out why I cant set a gunsight that will work for all the guns. The other planes all have several sights positions in gunsight select/options. It should have TU-2P, then TU-2 1, then TU-2 2, and so on. But it doesnt. Thanks.
