• SAE 9310 steel construction 
• Chromium nitride PVD 
• Near frictionless surface finish
• Fully compatible with Mil-spec sub-components
• Increased diameter cam pin hole eliminates most common bolt breakages
• Improved lug geometry for reduced wear and easier locking/unlocking
• Enhanced Ejector mitigates head case extrusions and reduces brass smear
• Enhanced Extractor optimizes extraction function and eliminates common ejection failures
• Enhanced Gas Ring reduced internal friction and carrier wear while maintaining near indefinite gas seal

The JP EnhancedBolt is made from SAE 9310 high-grade steel. This material makes for an extremely hard surface with a tough, ductile core resistant to structural failure and a life expectancy far exceeding Mil-spec 8620-type bolts. SAE 9310 is the same type of steel used in the transmission gears of Formula One race cars, and the high-load application of a bolt assembly is ideal for this state-of-the-art material; the results of actual full-auto endurance torture tests prove it. JP's world class bolts are now chambered in 6.5 Grendel for long range precision work.
