Electrochemical Rifled Barrels

[BlueFlyer]

Does anyone have any experience of barrels manufactured using this method? Should produce a totally stress free barrel.

Never heard of it before, if it works it might produce a good barrel, I’m leary of any sales pitch videos that don’t show the actual machine working and an actual finished product, as opposed to this bad animation
Edit to add, from my poor memory of arc etching, the higher the current rate the deeper the etch and the rougher the surface

McGowan is apparently going to use this method in the future, so it must be legit.
