This will probably not help with your animal spooking problem, but I did find that putting a small square of adhisive backed foam tape on the action (between the action and the cocking link) completely prevented the irritating cocking link rattle. It is a shame that it is needed in the first place, as there is a nice tight lockup upon closing the action which gives the impression of being well engineered, but then the cocking link flaps about all over the place.
