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.


  • 416 Stainless Steel
  • 5.56mm NATO Chamber
  • 1:8 Rate of Twist
  • Medium Contour
  • Standard 1/2X28 Muzzle Threading
  • Rifle-Length (12") Gas System
  • Barrel is DPT Inspected

Note: This is the barrel only, it is fully profiled and finished, headspaced, gas port drilled and inspected - it does not have a gas-block, front sight base, or muzzle device.
