Abstract
A crossbow includes a rail assembly and a limb assembly that can be assembled together and disassembled from one another. A release member is rigidly attached to one assembly and a retention member is attached to the other assembly. When the crossbow is assembled the release member is in a retained position; when the crossbow is disassembled the release member is removed from its retained position. In a release position the retention member permits movement of the release member into or out of the retained position; in a retention position the retention member prevents movement of the release member out of the retained position. The release and/or retention members can be adjusted to alter the force urging together the rail and limb assemblies. The retention member can be moved between the release and retention positions without using any tool.
