  • AR-15/M16 5.56 ENHANCED BOLT ASSEMBLY J P ENTERPRISES
    $118.99

    Item Code: #453217907

    Availability: In stock

    Designed For Extra-Long Service Life Complete bolt assembly 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. SAE 9310 steel 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. 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 further ensure smooth, reliable cycling. Bolts are available individually, or in a completion group, which includes the bolt, firing pin, cam pin and firing pin retaining pin.   Available caliber 223.

  • AR-15/M16 6.8 SPC ADVANCED COMBAT BOLT ASSEMBLY LWRC INTERNATIONAL
    $149.99

    Item Code: #453217907

    Availability: In stock

    Upgraded Design For Increased Durability & Dependability Updated design of the standard AR-15 bolt features a fully supported breech face and a dual-spring extractor system for extra strength and reliability to handle the 6.8 Remington SPC cartridge. Machined from an extremely hard steel alloy normally used in high-stress/heat applications like race car transmissions, then shot-peened and x-rayed for flaws before plating with a nickel-boron (NiB) coating. NiB coating significantly reduces friction coefficient, so the bolt is less likely to be hung up by fouling, and wear-resistance is greatly enhanced. Super-slick surface makes cleanup easy because carbon and gunk have a hard time sticking to it.
