The Altra Reinforced Concentric Outset System, commonly referred to as the A.R.C.O.S., is a masterstroke of engineering designed for those who demand excellence from their 166 arrow shafts. This system stands as an embodiment of durability and precision, crafted meticulously from the high-strength 7075-T6 aluminum. It is tailored to enhance both performance and reliability in archery.
At its core, the A.R.C.O.S. features an insert that penetrates deeply into your arrow shaft by 0.875 inches, ensuring a steadfast connection that forms the backbone of this robust system. Complementing this is an outsert that threads directly onto the insert—a design choice that encapsulates and fortifies the leading end of your arrow by 0.43 inches.
Precision doesn't stop at construction; pre-installed rubber O-rings are integrated within this setup to lock everything securely in place. These rings play a pivotal role in minimizing vibration during flight while enhancing concentricity—key factors contributing to improved downrange accuracy.
The versatility of the A.R.C.O.S. cannot be overstated—it comes available in four spine sizes, making it adaptable for various configurations sought by discerning archers aiming for optimal fit and peak performance.
