Highest precision and lowest tolerances, every nock size is made from the same mould
Asymmetrical design does not pinch the nocking point
Notice: Beiter 4.5/1 X is 19% heavier than a standard Out Nock, yet lighter than a standard pin nock system. Also 4.5/1 X may be used in conjunction with a pin and locks completely over pin and shaft. 4.5/1 X fits X10 shafts only.
