166 Phantom Titanium Outsert

The Pinnacle of Precision & Performance™ 166 Phantom Titanium Outsert pairs with our Altra Reinforced Concentric Outset System (A.R.C.O.S.), which fits our Altra Arrows Phantom 166 Shafts. Machined out of Ti5 titanium for unmatched durability and performance, with optimal fit options, this addition to your Phantom A.R.C.O.S adds the extra resiliance and weight you want for your arrow setup.  The insert secures into the arrow shaft at a depth of 0.875", while the titanium outsert then threads directly onto the insert and encapsulates the leading end of the arrow at 0.43" creating unmatched durability.  Essential rubber O-rings come pre-installed on the insert within the A.R.C.O.S., as they aid in locking the outsert in place which reduces vibration and improves concentricity between the outsert to the insert for a more precise arrow set up and down range accuracy. Features: Comes in 12 pk QTY Available in five sizes - 250, 300, 350, 400, & 500 spine 68gn Outsert Weight, 82gn Total Weight (when used with 7075 aluminum insert) Accepts micro FMS insert weights Altra Arrows highly recommends using a foam style arrow target when shooting arrows that have an ARCOS system, as the outserts can get stuck in filler of bag style targets which can damage the insert/outsert system or arrow.
