legal to have all black pellet gun in public?

I just had this conversation the other day. However the question was if it would be legal to ride down the thru way on my bike to the gun range with my SKS strapped to my back unloaded. I mean its unloaded and I am going to the range, and I do have the 2nd amendment. Wasn’t sure. You be the judge.
