These are the most prominent upgrade for a Spyder. The stupid-low price makes it impossible to pass up. If you don't want to take the time to mod in some eyes to your eyeless Spyder, put an ACS bolt in! The bolt has a spring that compresses in the case of a ball falling half-way through the breach, saving the ball and a lot of your time and effort cleaning your gun.
Truly ideal.
