Abstract
A high impact strength nock assembly that couples with, and decouples from, a bushing mounted in an arrow. The forces applied to the nock during launch are translated to the arrow through the bushing, greatly extending arrow life. For lighted nock applications, the nock translates within the bushing during launch to activate the light. A battery stop is coupled to the battery and releasably coupled within the center opening of the bushing that resists longitudinal translation of the battery relative to the bushing. Consequently, the light can be deactivated without removing the lighted nock assembly from the bushing. The entire lighted nock assembly is removable from the bushing for maintenance and replacement.
