Having watched all of the Fresh Tracks episodes, I have noticed in the first seasons the ends of the rifle barrels were black. I always thought maybe it was just a custom black end. In season 7 ep 3 it looked like the ends of the rifles had electrical tape on them. > If it is I'm assuming its to keep rain/snow out of your barrel??? > If it is do you take the tape off before you shoot or leave it on? >If its not tape what is it?
