I help people build LAWS and Cannons. Have Pictures and Word Files and help walk people though a build. Need to be 18 or have a parent correspond with me. Tell me about your access to equipment and skills using it so I can send you the right information. Some take some fabrication and others are just plumbing projects. Decide If you want 10 pound portable artillery meaning a 230 fps Nerf that will go 75-100 yards but you wont be able to carry a marker with it. Or if you want something about 6 pounds or less you can carry a marker with. If you want to be defensive only against tanks or be offensive as well and blow up bridges and bunkers in the 25-40 yard range. Send me a e mail to firstname.lastname@example.org
so I can attach the files and send them to you.
