Barrel Details

  • 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
  • Low Profile Gas Block

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.

 

Bolt & Bolt Carrier Details

  • 100% HPT & MPI
  • Shot Peened
  • Heavy Extractor Spring
  • Black Insert and O-Ring
  • Nickel PTFE Carrier

SIONICS bolts are made by a current defense contractor from Carpenter 158® Steel. The bolts are 100% high pressure tested and magnetic particle inspected. Each bolt is shot peened and comes with a heavy extractor spring, black spring insert and O-Ring.

SIONICS bolt carriers are also manufactured by a current defense contractor. Only M16 bolt carriers are used. The keys are checked for a flat fit before being installed and the bolts are side staked.

Each carrier assembly is treated with a durable Nickel/PTFE plating which creates a permanently lubricious surface which eliminates the need for grease, oil or any wet lubrication.
