ironsights problem

yesterday I was playing on a fallout 3 server (which was really fun :biggrin:) and I binded mouse2 to fl_ironsights because you had to hold down shift THEN click mouse2 to aim down the sights. so I start testing out some new addons in singleplayer and I cant aim down my sights on any of my weapons. then I knew exactly what the problem was, so I’m wondering what the console command for ironsights is.

still no answer?

no one knows how to fix this?!?!?
