Of a sort. The barrel is wider than the dart, and in theory the dart doesn’t even touch the sides, so the rifling only has an extremely minor effect on the air the dart displaces.
Yes this is the rifling. you have good eye. it is making the darts to spin and to be very much acurate. just like the real metal barell. i read this on the internet many many times so i now this is true. the ppls who say this is no true they lie. so every body knows this is double true;)
