Check with the Montana Rifleman
Top quality barrels and they will make them to any shape, length, flutes or style that you wish. The barrels shoot less than moa everytime if the gunsmith does his job. The prices are right and they a fantastic people to deal with.
In stainless, you could polish the barrel and bead blast the flutes. Blued, you would have to blue the barrel and either polish the barrel and bead blast the flutes prior to bluing or blue the barrel and paint the flutes. Either way you would end up with a very nice looking firearm.
Good shooting, John K
Anyone worth shooting is worth shooting more than once!
Stop crime, shoot back!
