Xtreme Performance Bolt (Relia-Bolt™) in DLC (Diamond Like Carbon)

The Sharps Xtreme Performance Bolt (XPB) in DLC (diamond Like Carbon), is our patented Relia-Bolt™ finished in DLC (Diamond Like Carbon) coating.

Patented technology

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?  The Relia-Bolt™ compensates by providing a patented camming action which guides the bolt past obstructions and into battery (U.S. Patent No. 9,863,729).

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.

100% Compatibility

Unmatched Strength and Durability

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.

Batch MPI and HPT tested

Tensile strengths of 1550-1600 mpa, or 220,000-235,000 psi.

Toughness of over 200 ft./lb. Charpy C-Notch

HRC of 46 yields a 15% increase in hardness at the same toughness comparing to Carpenter 158 & 9310
