Designed to pair with the Altra Reinforced Concentric Outset System (A.R.C.O.S.), these outserts are machined from Ti5 titanium for unmatched durability and performance. The insert secures into the arrow shaft at a depth of 0.875 inches, while the titanium outsert threads directly onto the insert, encapsulating the leading end of the arrow by 0.43 inches to enhance durability. Pre-installed rubber O-rings aid in locking the outsert in place, reducing vibration and improving concentricity for more precise arrow setups and downrange accuracy. Available in four spine sizes and with a total weight of 75 grains when used with the 7075 aluminum insert, these outserts offer optimal fit options for your arrow setup.
