In the realm of archery, precision and durability are paramount. The Altra Reinforced Concentric Outset System (A.R.C.O.S.) for 166 Shafts stands as a testament to engineering excellence, crafted to deliver unparalleled performance. At its core lies 7075-T6 aluminum—a material revered for its strength-to-weight ratio—ensuring that your arrows remain steadfast in their flight.
The A.R.C.O.S. system is ingeniously designed with an insert that anchors securely into the arrow shaft at a depth of 0.875 inches. This stability is further enhanced by an outsert meticulously threaded onto the insert, extending protection over the leading end of the arrow by an additional 0.43 inches.
Precision is not just desired; it’s achieved through pre-installed rubber O-rings which effectively lock the outsert in place, reducing vibration and promoting superior concentricity. This results in a more precise setup and significantly improved downrange accuracy—qualities every marksman can appreciate.
Available across four spine sizes, this system caters to those who demand optimal fit without compromise on performance. Whether you are perfecting your skill or competing at high levels, trust A.R.C.O.S.—where reliability meets innovation.
