knex automatic rifle
i had an idea to make a new (i think) type of knex machine gun. it is like knexwizard's semi auto rifle but it has a single shot trigger from viccie.b's crossbow. i made it but it fired its whole magazine (20 grey connectors) in one shot! after modifiying it to put tonnes of friction on the wheel that holds the bands i got it to fire its mag in two shots- still not good enough. can anyone help me?
