Barrels are getting fluted, then Cerakoted. Should then soon. My buddy and I are building twins.
Unless this is a new development, to the best of my knowledge Shilen are button rifled and lapped barrels. I own several (rifle) barrels from them and 1 Criterion, which is made the same way.
I think Shilen barrels are button rifled, not cut. I personally would not flute a barrel after it's been made. I'd want the fluting done by the manufacturer as part of the process to ensure the dimensions are correct on the finished product.
