    摘要: A firearm includes a slit receiver socket for detachably receiving a barrel, and a spacer element disposed between the rear of the barrel and the end of the socket to define the rearmost position of the barrel. The spacer element may include a plurality of discs which are adhered together. Discs may be added to or removed from the spacer element to adjust the size thereof.

    摘要: A firearm includes a receiver, a barrel, a bolt slidable in the receiver, spreaders mounted in the bolt for being pivoted into a locking recess on the receiver and a locking element for shifting the spreaders. The locking element includes rotatable spreader cams to extend the spreaders in response to rotation of the locking element in one direction, and includes unlocking cams operable to engage and shift the spreaders to a retracted position in response to rotation of the locking element in the opposite direction. A latch is provided to prevent the locking element from rotating relative to the bolt when the bolt is withdrawn from the receiver.

    摘要: A safety device for preventing unintentional firing of a gun comprising an easily-rotatable mass part mounted on the gun and having a stop which is in alignment with a recess in the triggering mechanism when the mass part is at rest, thus permitting movement of the triggering mechanism to fire the gun. When the gun is subjected to a force great enough to cause an unintentional firing, the mass part will be rotated by the force to a non-rest position wherein the stop is unaligned with the recess and prevents movement of the trigger mechanism for firing the gun. When the force diminishes, the mass part returns to its rest position to permit the gun to be fired.
