Making barrel rifling using steel tubes

In this video I will show barrel rifling for a 5.5mm, or .22 cal tube using an allen key. the same allen key method can be used for other calibers too, just make sure that the rifling button is 0.1mm-0.2mm bigger in diameter than the barrel inner (bore) diameter. In my case I used a 5.62mm button for a 5.48mm tube, and it worked quite well as you can see in the video. This barrel will be used for gas propelled PCPs.
