Description
The Altra A.R.C.O.S. Is a combined insert and outsert system for Altra arrow shafts in 300 spine. The insert goes into the shaft at a depth of 0.875"; the outsert threads onto it and covers the front end of the arrow shaft at 0.43". Total combined weight is 50 grains, and the system accepts micro FMS insert weights. Pre-installed rubber O-rings on the insert lock the outsert in place to reduce vibration and improve concentricity. Check fit for your arrow diameter and spine; the system is available in 250, 300, 350, and 400 spine. Browse arrow components and add the tools you need to build your arrows.
