Yes, is possible. Use 304 Stainless steel.

The Null22 is designed for smooth bore and has a suppressor in the package

can a smooth null use suppressor？I think the bullet well hit the suppressor inside

5.5mm would be good for ECM rifling, but I suspect the bullet will get stuck in a stock 5.5mm tube.
