Located in Gladstone, MI, Marble Arms has been manufacturing gun sights and other wares since 1892. Gun sights are the company’s most enduring product, but they also produce knives, axes, compasses, matchboxes and scopes.
For more than a century, workers there made sights by hand. In 2010, Marble Arms decided to automate the process to increase productivity. The company turned to Lake Superior State University’s Product Development Center (LSSU-PDC) for help. Marble Arms had learned of LSSU-PDC through the Michigan Small Business and Technology Development Center (MiSBTDC).
