The American Rifle Company has revolutionized the shooting experience with its innovative Nucleus and archimedes rifles, designed to seamlessly integrate savage-style small-shank barrels. This unique feature empowers rifle owners to effortlessly mount their own barrels, eliminating the need for a gunsmith and transforming these rifles into versatile, multi-caliber platforms with minimal effort. Central to this adaptability is the ARC bolt head and extractors kit, which enables users to easily switch calibers. Each ARC bolt head is precision machined from hardened steel and enhanced with a DLC coating, providing exceptional resistance to wear and corrosion. Available in a variety of popular calibers, these bolts allow you to simply swap out your barrel and explore new calibers with your reliable ARC action. Compatible with both Nucleus 2.0 and archimedes actions, this system offers unparalleled flexibility and performance for the discerning shooter.
