US Patent 10359247 Folding stock with barrel clamp

A folding stock with barrel toggle clamp has a body defining a receptacle adapted to receive the action, a clamp mechanism on the body operable to move between a released position and a clamped position, and the clamp mechanism operable to bias the barrel toward the receptacle to secure the barrel to the action. The clamp mechanism may be a multi-link linkage. One of the links may have an adjustable length. The clamp mechanism may include a lever that is flush against an external surface of the stock when in the clamped position. The clamp mechanism may include a V-block defining a channel adapted to receive a protrusion on the receiver and an angled surface on the barrel to clamp the barrel to the receiver. The clamp mechanism may include a lever pivotally connected to the body to pivot on a first horizontal axis lateral to the body.
