I'm not sure what you meant to say I'm right about. But we agree that Damascus patterned barrels are esthetically pleasing, I think.
The truth is I don't make barrels like those: I make only barrels of modern steels, because the materials lend themselves to better, safer products. Esthetic appeal can be added in a number of ways, but I wouldn't sign-up to any which might impact the safety or efficiency of the rifle when completed.
If, as I surmised, the BRNO barrels are made with only an external veneer of Damascus steel, no sacrifice of safety need be made, though I am unsure what impact a composite structure for the barrel might have on accuracy - and I always advise in favor of accuracy, when asked. I have done 'cosmetic' alterations to the external surfaces of rifle barrels (fluting, octagons, etc.), but only after advising the customer that any external alterations made to an (internally) finished barrel can only have a negative impact on accuracy, and the best one can hope for is that the rifle shoots acceptably well when finished. Barrels made in our shop always have shot exceptionally well, but that is probably because every operation is done by the barrel maker himself, and no 'seconds' ever leave the shop.
