I would say damn near all of them.
If the OP is talking about bolt rifles, damn few of them. A few more details would help.
If you are talking about bolt rifles I'd not worry too much. A low powered optic is better in every way. If you still insist on iron sights I would still pick the rifle I wanted first. If it happens to have irons fine. If it doesn't then I'd pay a gunsmith to put them on it. It is not that expensive, cheaper than buying a cheap scope and mounts.
I'd rather do that than buy a sub-par rifle just to get iron sights.
