Panzer Arms Complete M4 Tactical Barrel Assembly - Nickel

Gas Piston - Processed from 50 White Chrome Vanadium Thanks to the vanadium-alloyed steel, hardness and fatigue resistance are increased; the White Chrome coating provides protection and smooth operation while reducing residue buildup.Gas Port Chamber - Made from 420 stainless steel, it offers corrosion resistance and dimensional stability. It ensures consistent gas cycling, improving the reliability of the firing sequence.Bore - White Chrome Lined When the bore's inner surface is coated with white chrome, friction, powder residue, and corrosion are reduced - resulting in easier cleaning and long-term accuracy.Barrel - Drilled from 4140 Italian Steel The main body of the barrel is machined from a single piece of high steel such as 4140, providing the rigidity required for accuracy and long-lasting durability. Precision drilling guarantees consistency in internal geometry, ensuring accuracy and uniform shot patterns.Mobile Chokes - 4140 Steel (C,M,F Options) Interchangeable chokes made from 4140 steel are available in Cylinder (C), Modified (M), and Full (F) options, allowing control over shot dispersion to achieve the desired spread pattern. All of the barrels come with 3 chokes which are threaded in Benelli Mobil thread pattern.
