Barnett replacement rubber band for slingshot
A slightly more advanced model, the Diablo slingshot has an ergonomic rubberised "pistol" handle for a better grip and an adjustable armrest to relieve the wrist and increase shooting accuracy.
The Pro Diablo stone thrower is even more technical than the other models of the Barnett brand. In addition to an ergonomic rubberised handle and an extendable armrest, it is equipped with weighted, antenna-shaped stabilisers that provide inertia and limit shaking.
