Yes tape over the muzzle.
I had an unfortunate incident in the Southern Alps (Godley) where I fell over and pushed my rifle's barrel hard into the snow. My rifle was disabled until we got back to the bivy where we had a cleaning rod. I tried cleaning it with a pull I carried through but couldn't get it to drop thru the barrel and push out the slush.
For some reason, back then, noboby bothered to tape the end of their barrels.
And yes, definitely remove the suppressor when storing the rifle barrel up. Many a barrel has be f....d by moisture running down into the barrel end and causing severe corrosion.
