When you demand the utmost reliability and precision from your .308 rifle, every component counts.

Key Features & Benefits

  • Exact Thread Specification: Precision‑cut .625 × 24 (UNC) threads match the standard .308 barrel profile for a perfect fit.
  • Robust Outer Diameter: A .920 in outer diameter provides a solid, protective barrier against impacts, debris, and wear.
  • Matte Finish: The low‑gloss black coating reduces glare, resists corrosion, and blends seamlessly with tactical and hunting optics.
  • Premium Material Construction: Made from high‑grade stainless steel with a nitride treatment for superior strength and longevity.
  • Easy Installation: Thread‑on design requires no special tools—simply screw onto the barrel and torque to the manufacturer’s specification.
  • Preserves Barrel Integrity: By shielding the thread area, the protector prevents thread stripping, cross‑threading, and premature wear.
  • Universal Compatibility: Designed for all .308 rifles with standard .625 × 24 barrel threads, including AR‑10 platforms, tactical rifles, and precision shooters.
