Theoretically, you can open carry everything you mentioned. With long guns you even get the bonus of being able to into bars without asking permission. Of course you still need tax stamps for the fun stuff and follow all the laws pertaining to Open Carry; School zones, government buildings, etc.
Realistically, if you are taking a stroll especially in Madison or Milwaukee with your SBR'd and suppressed AR expect an encounter with some freaked out dudes with badges and possibly some guys with SWAT written across their chest.
With a concealed carry permit you may only carry pistols concealed or in prohibited places. As an aside AR and AK pistols meet the letter of the law.
