Insane Pain sports makes some of the best custom internals for Spyders, and this is no exception. I have almost no kick, and it increased my velocity by 20 fps! Also quiets the gun down quite a bit. The three o-rings allow for a greater seal, making it more air efficient, and overall, a great bolt.
