Gamekeeper John is an international slingshot champion, world famous catapult frame designer and YouTube legend and we've been working with John since we first started making catapults. Starting with casting a handful of prototypes, we've worked closely with John over the years to bring you the greatest of his world famous designs cast in high-grade aluminium and bronze so you can have well balanced, ergonomic and hard-hitting metal slingshots that will last a lifetime. From the earlier models to the PPSG and PPMG and on to the refined result of our efforts - the new PPMG+ - we're continuing to work with John to keep bringing you amazing catapult designs that we're proud to make and always happy to shoot.
