either the tethered motor pack (easiest to work with), black motor (2nd fastest) or all terrain trekker (fastest/strongest) all but the trekker motor are available on knex.com

 the blue one!
This would be the best one for machine guns (the only type of gun that uses a motor) because you can have the on and off switch right at the handle and have the gear box a ways away. http://www.knex.com/building_toys/tethered_power_pack_motor.php
