Question about "Ghost in the Shell" (the original movie, not the series)?

Question

In the scene somewhere after the middle, nearing the climax, the main character chick is arming a rifle in the back of the van as her partner's driving.
What kind of rifle is that?

I can't settle for the explanation that it was a made-up weapon. All other weapons presented are actual or customized actual weapons (ie, uzi w/ armor piercing rounds)

Your link was not complete. I browsed in the area, and If you are talking about the weapon in gs532, then it might be the P90, a submachine gun developed and manufactured by Fabrique Nationale de Herstal (FN Herstal).
