But if you are set on equipping yourself with irons, the only way you could use them, assuming you go with any scope, would be to mount the scope on a QR base (LaRue, ADM). That's because before you could user your irons, you'd need a way to ditch the scope. This type of QR base will run $175-200, depending on who you go with. With a QR base, you would still need to plunk down $175+ for the scope, $125+ for a folding rear BUIS (a fixed BUIS will not work with a scope) and another $125-150 for a folding front BUIS/or somewhat less for a fixed, clamp-on BUIS.
My experience is, that with my 2-7X scope, my fixed FSB is not visible in my FOV when looking through the scope, so don't assume you require a front folding BUIS. But you would need a rear folding BUIS, I don't see any way around that.
If your sighting system budget is really $200-300, I don't see how you're going to be able to equip yourself with any decent optic and irons. At that budget level you are going to have to pick one or the other. Seeing as how you didn't mention SD as a usage of your carbine, I'd go the optic route myself. JMHO.
