ABSTRACT:
An arrow point with a selectably-adjustable, incrementally-stepped array of weight-regulating elements. The weighting elements are demarked lineal component segments of an elongate rod or bar which is deeply grooved radially at incremental, lineally-spaced positions along its length. The rod is threaded at its forward end for coupling engagement with a threaded neck portion of the arrow point. Prior to sleevedly assembling the arrow point with the shaft of the arrow, the segmental rod is severed at a particular pre-set groove to leave a selectable number of weight segments attached. The latter remain as a secured, weight-adjusting core component of the arrow point assembly. An O-ring seated in a diminutive, outwardly-opening annular groove formed in a sector of the rod forwardly of the segmental array bears upon an enveloping inner wall of the body of the point assembly to stabilize and to lock the rod frictionally within the core of the arrow point.
