发明名称 Compact Crossbow with Improved Efficiency
摘要 A "cross-over" compound crossbow includes a stock and barrel assembly attached to a horizontally mounted compound bow. The compound bow component is similar to that of U.S. Pat. No. 7,047,958 and includes an alternative arrow support system to achieve higher arrow velocity at a reduced draw weight. The crossover compound bow also provides draw weight adjustability and positive cam synchronization.
