发明名称 Powerstroke Crossbow
摘要 A crossbow having an increased powerstroke and reduced noise. The powerstroke is increased by inverting the limb orientation from the standard crossbow arrangement and locating string guides at least partially forward and rearward of the ends of the limbs. The bowstring is drawn from the tops of the string guides to maximize the powerstroke, reducing noise and increasing the retained and delivered energy over existing crossbows.
