Sharps XPB 5.56 Bolt NP3 Coated

The redesigned lugs of the Relia-Bolt™ virtually eliminate the most common MSR malfunction; the bolt to barrel extension jam. Haven’t cleaned your rifle? Is it out of time? Relia-Bolt compensates by providing a patented camming action which guides the bolt past obstructions and into battery. The rounded/tapered lugs push past carbon and debris when the square edges of traditional bolts would typically jam. Once into battery, the rear edges of the lugs fully engage the barrel extension for absolute strength and security.

Unmatched Strength and Reliability                                                 The Relia-Bolt is machined from S7 tool steel and tempered with SRC’s 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. 

Superior Corrosion Resistance                                                           Every Relia-Bolt is coated with NP3®/NP3® PLUS, an electroless nickel-based finish. This process co-deposits sub-micron particles of PTFE (polytetrafluoroethylene), commonly known as Teflon™, for self-lubricating corrosion resistance.  NP3® PLUS offers far more corrosion resistance for marine and other hostile environments. NP3® PLUS gain up to five times as much corrosion resistance over standard NP3® and up to 10X more than regular electroless nickel!

MPI, HPT, and Shot-Peened                                                               Magnetic Particle Inspected, High Pressure Tested, and Shot Peened, the Relia-Bolt is guaranteed to perform under pressure.

Lifetime Guarantee                                                                              If any Relia-Bolt is found to have defects in materials or workmanship, SRC will repair or replace it at no charge. You do not need to be the original owner, and no time limit applies.
