The Cure 4 has been designed to reduce paintball fracture during the firing sequence caused by Bolt Strike. Bolt Strike is a phenomena seen when the bolt accelerates into the face of the paintball as it pushes it into the barrel prior to firing. The Cure 4  incorporates a soft leading portion of the bolt that not only reduces the impact on the ball being launched, but is also flexible enough to prevent clipping of the stack above the breech as the bolt drives forward. The design of the Cure 4 also means that the soft tip can be quickly and easily removed and replaced without the use of tools or adhesives, whilst the mechanical locking mechanism keeps it securely in place during use.
