- Carrier: Machined from 8620 steel & QPQ nitride/melonite treated.
- Improved carrier geometry with M16 profile.
- The QPQ nitride/melonite treatment hardends the surface to 70 RC and reduces friction, adding corrosion resistance inside and out.
- Bolt: 9310 & QPQ nitride/melonite treated with additional cryo freeze for extra strength. Shot peened precision ground diameters.
- Magnetic particle inspected and laser marked.
- Extractor machined from 4140 hardned steel
