From the manufacturer
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.
