Image Number 6 for United States Patent #6481142.
A recoil reduction lock for a gun prevents a recoil reduction device from compressing until a shell is discharged. The lock is adjustable so that it may be used with different gun stocks. The lock may be configured to work with a wide variety of existing recoil reduction devices. The lock includes an inertia lock that prevents a gun stock from collapsing until the discharge of a shell moves the inertia lock to an unlocked position. The inertia lock rapidly returns to its resting position enabling the gun to be rapidly fired again.
