Altra 204 Insert and Outsert 250 Spine

Description

The Altra Reinforced Concentric Outset System (A.R.C.O.S.) is designed for Altra Arrows 204 Shafts, offering unmatched durability and performance through its precise 7075-T6 aluminum construction. The insert secures into the arrow shaft at a depth of 0.875 inches, while the outsert threads directly onto the insert, encapsulating the leading end of the arrow by 0.43 inches for enhanced durability. Pre-installed rubber O-rings lock the outsert in place, reducing vibration and improving concentricity for a more precise arrow setup and increased downrange accuracy.
