Making barrel rifling using steel tubes

Fund my projects: https://buymeacoffee.com/pcpairgunsch...

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 0.1mm0.2mm 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.
