From the manufacturer
Lasts Up To 10X Longer
The J P Enterprises Complete Bolt Assembly (Enhanced) for 6.5 Grendel / 6mm ARC 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 JPE Enhanced Bolt Assembly for 6.5 Grendel / 6mm ARC 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. This is the same steel used in the transmission gears of Formula 1 race cars, so it’s ideal for high-impact, high-heat applications like sustained full-auto fire.
J P Enterprises has meticulously machined radiuses on all 90-degree corners on the locking lugs to help distribute impact force evenly and further reduce risk of premature wear and cracking. Fully supported extractor face and precise extractor engagement further ensure smooth, reliable cycling of your favorite firearm.
