This week on Top Tech Challenge! Aaron vs. Spencer! We take a bare bones G4 and the techs have to make it the best possible SPR (Special Purpose Rifle). Except, this time, each stage is timed, meaning that they only have 30 minutes for the gear box and 30 minutes for the body. Mix that in with some shooting challenges, and you have a tech challenge that will really push these guys to the limit. Be sure to check these guns out on our website!
