To provide the barrel with fantastic corrosion resistance and extreme hardness for the long haul, the 1:7" twist barrel has been nitrided.

The small details are important.
The extraordinary green o-ring has been tested to not bind, even at -40°F. To ensure the longest possible life for your extractor spring, they've made it from premium ultra-strong wire in a low-fatigue design. Don't worry about gas leakage. The properly-staked carrier-key with Permatex® gasket-seal compound ensures that won't happen.
