Lately I wonder, how Accurate can a Lego Rifle shoot? And started to build a Lego Rifle that shoots 6 mm Steelballs. At a Distance from 5,5 Meters it works great. But the Tigger mechanism was to weak for more Rubber. So I rebuild it and Chance the whole Concept. Now it is a Sideshooter Slingrifle with serial Power. Shooting 7 mm Steelballs with a Speed of 90 m/s. That is 7,5 Joule. With a Lego Gun😁 And it is Accurate too.
