Any one know if the Smooth Twist Barrel has a patent? I like the smooth twist and I figured out how to make it. FX get $200.00 each and I would like to make my own air gun.
I got two barrel from one other supplier from Europe. Again big bucks $. And did not perform as good as the smooth Twist design.
