Crosman Rabbit Stopper/Ratcatcher  tuning kit.
Includes:
Set of 3 different strength springs
Spring Guide
O-Ring set

Do not fit to the pistol if you live in the UK, as this could put it over our 6 ft limit. Especially if you have our rear dove fitted.
Always check the power to make sure the gun does not exceed your limit, after changing any parts.
