BE.S.T. (Benelli Surface Treatment) is a new proprietary finishing technology developed by engineers and scientists at Benellis manufacturing headquarters in Urbino Italy. This coating protects steel with a tough, impenetrable armor that stops rust and corrosion.BE.S.T. (Benelli Surface Treatment) is a new proprietary finishing technology developed by engineers and scientists at Benellis manufacturing headquarters in Urbino Italy. Spending more than a decade developing BE.S.T., this coating provides corrosion and abrasion resistance that is superior to any other firearm finish on the market.It is a hybrid Physical Vapor Deposition (PVD) and Plasma Enhanced Chemical Vapor Deposition (PECVD) technology that applies a protective coating to parts. PVD and PECVD processes utilize electricity, radio frequencies, and plasma in a high vacuum environment to deposit a solid coating that precisely and uniformly covers the treated parts.While these technologies have been used in many industries for some time, applying them to a shotgun barrels had never been practical until Benellis breakthrough. Typical deposition processes operate at high temperatures. Treating a shotgun barrel in such an environment would ruin the ballistic properties of the barrel and weaken the strength of the barrel extension. Benellis engineers created a process that completes the process at low temperature, maintaining the perfect ballistics of our Crio-treated barrels and the heat-treated strength of the barrel extension.BE.S.T.
