Some footage on airsoft springs from MadBull Airsoft... "During a routine cleaning of the Madbull video library, we came across this old footage from the Madbull labs. Here now is scientific proof that Madbull springs are awesome! The video is old and hilarious to watch now because we are in the future. Please don't take this too serious, especially our hair. Remember, we are professionals so don't try this at home."
