Their chrome lined barrels are 11595E 41V50 Steel, NATO Chamber, and X-Ray and MP Inspected! Their Bolt and Bolt Carriers are 100% HPT & MPI, Shot peened and the carrier is Nickle/PTFE plated.

    SIONICS barrel blanks are made from MIL-B-11595E Certified (41V50 CMV) Steel. They are chambered and rifled to best suit the purpose of each particular barrel. The gas ports are properly sized. The barrels are finished with hard chrome bores and chambers. After completing a Quality Control inspection of the raw blanks, each barrel is checked for proper headspacing, profile dimensions, gas port size and location. Muzzle Crowns are inspected under magnification.

    All SIONICS barrels receive a durable Manganese-Phosphate outer finish.

    SIONICS barrels are 100% X-Ray and Magnetic Particle inspected by an independent ANSI Certified facility.

    Feed ramps and chambers are lightly polished and if required, front sight bases are installed in a custom alignment fixture using hardened and tapered cross pins. Every barrel is test fired to ensure reliability, function and accuracy. Any barrel that does not pass every test and inspection is rejected.

    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.

    I've also heard good things about Sionics and they do well in the new M4 Chart.

    Thanks for always offering quality products at a great price, X!
