This is SIONICS premium, stainless steel precision barrel. The slightly heavier profile and design makes this a practical design that is more than capable of sub MOA accuracy. The barrel is 18.5 inches long and uses the standard Rifle Length Gas System - SIONICS found that the extra half of an inch helps provide additional back pressure and dwell time needed to make the rifle 100% reliable, without having to over drill the gas port, or use a mid-length or proprietary gas system.
