ABSTRACT:
An improved arrow system comprises an arrow shaft having first and second tubular end sections each having substantially parallel inner and outer surfaces, and an intermediate tubular section which is fixedly coupled between the first and second tubular end sections and having an inner diameter which is greatest at its ends and which decreases toward the longitudinal center of the intermediate section. An adjustable weight arrow point assembly co-operates with the first tubular end section while an adjustable weight self-aligning nock assembly co-operates with the second tubular end section. The coupling between the arrow point and shaft also provides for alignment of the former on the latter.
