Crafted from 7075-T6 aluminum, this system includes an insert that 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. Pre-installed rubber O-rings help lock the outsert in place, reducing vibration and enhancing concentricity for a more precise arrow setup and improved downrange accuracy. Available in four spine sizes, the A.R.C.O.S. system is perfect for those seeking optimal fit and performance.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eFits Altra Arrows 166 Shafts\u003c\/li\u003e\n  \u003cli\u003eMachined from 7075-T6 aluminum for unmatched durability\u003c\/li\u003e\n  \u003cli\u003eSecure insert depth: 0.875 inches\u003c\/li\u003e\n  \u003cli\u003eOutsert encapsulates arrow end: 0.43 inches\u003c\/li\u003e\n  \u003cli\u003ePre-installed rubber O-rings reduce vibration and improve concentricity\u003c\/li\u003e\n  \u003cli\u003eComes in 12 pk QTY\u003c\/li\u003e\n  \u003cli\u003eAvailable in four sizes: 250, 300, 350, \u0026amp; 400 spine\u003c\/li\u003e\n  \u003cli\u003e50gn Total Weight\u003c\/li\u003e\n  \u003cli\u003eAccepts micro FMS insert weights\u003c\/li\u003e\n  \u003cli\u003eEnhances downrange accuracy and precision\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Altra","offers":[{"title":"Default Title","offer_id":44395625742393,"sku":"1502401","price":74.69,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0583\/1422\/7769\/files\/1b597eac074c6d603e72dde51fd830a2.jpg?v=1743872257","url":"https:\/\/archerywarehouse.com\/products\/altra-166-outsert-titanium-300-spine-1-dz","provider":"Archery Warehouse","version":"1.0","type":"link"}
