Allow the use of BUIS for more weapons

[saXoni]

Hello Devs and Devdettes (?)

Is there, except for the blatantly obvious one, a reason why weapons/scopes without BUIS aren't allowed to take aim using the same mechanic? Balance purposes, perhaps?

I'm no firearms or military expert, but it seems like the natural thing to do when you're in CQB with a scope. Especially when you consider how, except for the very first shot, inaccurate hip firing is.
