RX7 23 spine - uses 2315 X7 parts. Selling as out of spine for my bow. Bought new last week. Each arrow shot no more than 5 times into foam. 77.2mm / 30.4" AMO length - measured using Beiter 19 knocks, which aren't included. 100grn Easton bullet points. 4" feathers on 4 of the shafts. 2 bare shafts. No nocks included - use your nock of choice. Feathers are taped on so easy to remove if you want to use something else.
