1. A weapon aiming system, comprising:
a riflescope having at least one turret for adjusting the position of an internal reticle aimpoint;
at least one encoder that senses a relative position change of at least one of the turret and the reticle;
a laser rangefinder (LRF) associated with at least one pair of Risley prisms operable to adjustably position a LRF aimpoint to coincide with the aimpoint of the riflescope reticle;
a controller;
a motor associated with each Risley prism and controlled by the controller to position the associated prisms;
wherein the system is configured such that adjusting the aimpoint of the riflescope reticle causes the encoder to send a position change signal to the controller programmed to, in response, direct the motors to reposition the prisms so that the LRF aimpoint continues to coincide with the reticle aimpoint.
