{"product_id":"altra-204-insert-and-outsert-400-spine","title":"Altra 204 Insert and Outsert 400 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.","brand":"Altra","offers":[{"title":"Default Title","offer_id":44753823760418,"sku":"1502409","price":54.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0783\/9780\/0482\/files\/285187967.jpg?v=1768773198","url":"https:\/\/shop.finalstalk.com\/products\/altra-204-insert-and-outsert-400-spine","provider":"Final Stalk","version":"1.0","type":"link"}
