DEMIBLOC BARRELS. The new Beretta SO10 over-and-under boasts demibloc barrels, manufactured for the first time using an exclusive process of cold hammer forging. The perfect concentricity of the tubes obtained with this system ensures lightweight barrels and exceptional strength. Years of flawless performance are guaranteed. Two bands on the sides of the barrels help fitting between the fore-end and the tubes, and enhance the contact of the fore-end with the surface of the barrels. The two bands, together with the side and top ribs, are softsoldered using a low-fusion alloy that causes less deformation of the steel during welding and preserves the outstanding properties of flexibility, and high tensile and impact strength. The top rib is finely hand checkered to reduce glare. The barrels are formed of extremely resistant steel made of a special nickelchromium-molybdenum alloy. The cartridge chambers and the bores are hard-chromed for extra corrosion resistance, extended barrel life and more consistent shot patterns. The deep and gloss blueing of the barrels is the result of repeated black oxidations and painstaking hand work. All the metal surfaces are polished carefully by skilled Beretta artisans. - 67 -

DEMIBLOC BARRELS.
The new Beretta SO10 over-and-under boasts demibloc barrels, manufactured for the first time using an
exclusive process of cold hammer forging. The perfect concentricity of the tubes obtained with this system
ensures lightweight barrels and exceptional strength. Years of flawless performance are guaranteed. Two
bands on the sides of the barrels help fitting between the fore-end and the tubes,
and enhance the contact
of the fore-end with the surface of the barrels. The two bands, together with the side and top ribs, are soft-
soldered using a low-fusion alloy that causes less deformation of the steel during welding and preserves the
outstanding properties of flexibility, and high tensile and impact strength. The top rib is finely hand
checkered to reduce glare. The barrels are formed of extremely resistant steel made of a special nickel-
chromium-molybdenum alloy. The cartridge chambers and the bores are hard-chromed for extra corrosion
resistance, extended barrel life and more consistent shot patterns. The deep and gloss blueing of the barrels
is the result of repeated
black oxidations and painstaking hand work. All the metal surfaces are polished
carefully by
skilled Beretta artisans.
