J P ENTERPRISES AR-15 6.5 GRENDEL/ 6MM ARC ENHANCED BOLT ASSEMBLY | Sinclair Intl

Life of up to 60,000 Rounds

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 high-impact, high-heat applications like sustained full-auto fire. Meticulously machined radiuses on all 90-degree corners on the locking lugs help distribute impact force evenly and further reduce risk of premature wear and cracking. Fully supported extractor face and precise extractor engagement of the 6.5 Grendel / 6mm ARC rounds, further ensuring smooth, reliable cycling.
