Kinda' depends on what town you refer to when you say "around the town's sidewalks".
Check the laws in the places you would do so. They often stipulate "concealable" or not. I personally wouldn't tote a rifle, although I often have my AK in the gun rack in the back window of my truck.
I wouldn't pack it around town. (My name isn't kwikrnu!) Although I wouldn't do it, I can't be judgemental on whether you do or not. I merely advocate obeying the law.
I'm not the one going to jail if I misread it.
If you do, good luck.
