On display at the RedWolf Airsoft booth during the IWA Outdoor Classics were the Alpha-Tec Impact Grenades that can be sourced from RedWolf Airsoft UK and here is Tim to tell you more about these... "The Alpha-Tec impact grenades are very durable and most definitely reusable as it's made out of high quality aluminium and steel. They'll only be sold around Europe and will most likely make their way to America if permitted."
