J P Enterprises Ar-15 6.5 Grendel/ 6mm Arc Enhanced Bolt Assembly

The J P Enterprises Enhanced Bolt Assembly has been designed to offer superior performance for the 6.5 Grendel and 6mm ARC. The bolt is precision machined from an ultra-strong steel alloy to last up to 10 times longer than a standard carbon steel bolt, minimizing the risk of bolt failure during a critical engagement. Made from SAE 9310 steel the J P Enterprises Enhanced Bolt has a tough, ductile inner core highly resistant to stress fracturing, with a hard outer surface that resists galling and wear, to ensure a service life of up to 60,000 rounds. The JPE Enhanced Bolt Assembly offers the same steel used in the transmission gears of Formula 1 race cars, so it's ideal for Mfg: J P Enterprises SPECS: SAE 9310 nickel-chromium-molybdenum steel, black nitrate.
