Abstract

The present specification describes novel arrow inserts and arrow systems that may be used for archery. One aspect of the novel arrow inserts relates to two or more separated contact portions or fit rings. The use of at least two fit rings contacting an inside diameter of an arrow shaft at a spaced interval provides better alignment of the arrow insert, and thus an arrow point, with the arrow shaft. The novel arrow inserts may be formed with a lip to limit insertion into the arrow shaft, or without a lip. Inserts without a lip may allow the insert to be fully inserted into the arrow shaft. The inserts may be sized to fit snugly into any arrow shaft, including reduced diameter hunter arrows described herein. The inserts may also be sized to accommodate standard arrow point assemblies, half-out arrow point assemblies, or smaller diameter arrow point assemblies.
