Abstract: In a crossbow of the type wherein a bolt is supported solely at its front and rear ends, a spring-loaded bolt stabilizer is provided which cooperates with the front bolt rest to maintain a bolt in position. The stabilizer may be pivotally mounted on the crossbow and biased toward a bolt-engaging position by a coil spring, and a finger tab may be provided to permit the stabilizer to be pivoted upwardly to facilitate placing a bolt on the bolt rest.
