Description
The redesigned lugs of the NP3 Extreme Performance 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™ from SRC 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.
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.
Superior Corrosion Resistance
Every Relia-Bolt™ is coated with NP3® , an electroless nickel-based finish. This process co-deposits sub-micron particles of PTFE (polytetrafluoroethylene), commonly known as Teflon™, for self-lubricating corrosion resistance.
100% Compatibility
Relia-Bolt™ is drop-in compatible with all existing .223/5.56 variant parts groups and bolt carriers; no modifications or tools are necessary for installation.
