There is a common thread among winners...consistency. Serious shooters and hunters know consistency in their equipment gives them the edge to win on the course or in the field. Every Carbon Express shaft is laser checked for straightness and sorted for weight. CX shafts designated with the term "Select" are +/- .001" in straightness and weight sorted +/- 1 grain within the dozen. Weight tolerance will be within +/- 2.0 grains. Black finish.
