Being a bit of a traditionalist, and valuing five shots in the magazine when the rifle is carried with an empty chamber...which maker currently lists a 280 REMINGTON calibre rifle with both that capacity and iron sights as well as 'scope rails? A barrel longer than 22" would also be helpful!

If not what is the closest that I can get? Ruger's Hawkeye looks very attractive, but no iron sight and only a four magazine capacity.
