The inner surface of the barrel is plated with hard chrome. This can equalize the distribution of heat during thermo plastic resin meltdown. Installing this thermo mixer with an extrusion mold, allows you to finely control temperatures, so you can reduce variances of polymer's meltdown temperatures (and viscosity) that occur with extractors.
Unlike chrome lining, QPQ is a treatment instead of a coating. It increases the life of the barrel but does not actually add any material to the barrel as to not affect the accuracy of the barrel. All Aero Precision Ballistic Advantage CMV Barrels are QPQ coated both inside and out.
