Our company has been using the bullet mole system for over 10 years now and its been a staple for our underground boring jobs. We prefer the bullet mole over the missile for most applications, especially 2" and under pipe. The shafts, points, and accessories are all well made and well thought out for contractors to get the job done. Over the years we have added more shafts, points, and accessories so we can avoid bringing a missile whenever possible. Awesome tool that has never failed us and great personal customer service to go with it.
