Features of Sharps Rifle Company Xtreme Performance Bolt

  • The Relia-Bolt is machined from S7 tool steel and tempered with SRCs proprietary heat-treating process, significantly increasing strength when compared to MilSpec Carpenter 158. S7 provides a 75% increase in tensile strength, and nearly 60% improvement in yield strength.
  • Every Relia-Bolt is coated with Nib-X (Nickel Boron), an electroless nickel-based finish. This process co-deposits sub-micron particles of PTFE (polytetrafluoroethylene), commonly known as Teflon, for self-lubricating corrosion resistance.
