The Eclipse 07 Ego Zick Kits is a Stainless Steel Ram and End Cap combo that work together to reduce the kick of your ego dramatically.  The ram and cap combo create an air cushion for the ram to bang against in the back of your 07 Ego. This air cushion absorbs the impact of the ram, dramatically reducing the kick of your gun. These are the same kit in the $2,000 SL74 EGO. Warning using a titanium ram will break the valve steam in your Ego.
