The Xbow Fletching Adapter is perfect for fletching any and all Xbow bolt types. It doesn’t matter if you’re using a flat nock, half moon nock, omni nock or no nock at all; this adapter is just for you. This unique design allows the adapter to spread apart, then compress back together using springloaded tension; to hold tight onto any and every crossbow bolt. It also has the ability to function on many different fletching jigs. This new adapter has an internal alignment pin to ensure the arrow sets straight inside the adapter while in use.
