Abstract: An image stabilization or vibration reduction facility for a riflescope and firearm has a transparent optical element that refracts incoming rays passing based on motion, to provide a stabilized image, which is transmitted to a user along an optical path of a rifle scope. A feedback transducer connected an output signal from the stabilization facility indicates a characteristic of the output signal. The transducer may be a second reticle that moves based on motion of the riflescope to indicate the degree of deflection by the stabilization facility, and may illuminate when the stabilization facility is in a neutral condition without deflection. The rifle may include a trigger block the prevents trigger operation until a neutral condition is detected.
