{"product_id":"altra-insert-and-outsert-166-250-spine","title":"Altra Insert and Outsert .166 250 Spine","description":"The insert secures into the arrow shaft at a depth of 0.875\", while the 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.","brand":"Altra","offers":[{"title":"Default Title","offer_id":44738840035362,"sku":"1501740","price":54.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0783\/9780\/0482\/files\/285188080.jpg?v=1768411929","url":"https:\/\/shop.finalstalk.com\/products\/altra-insert-and-outsert-166-250-spine","provider":"Final Stalk","version":"1.0","type":"link"}
