Summarized by Shop
The Pinnacle of Precision & Performance™ Altra replacement O-rings for the A.R.C.O.S. are essential in the insert/outsert system as they aid in locking the outsert in place, reducing vibration and improving concentricity between the outsert to the insert for a more precise arrow set up and down range accuracy.
