Grand Products Inc.

Grand Products Inc. is a niche pinball manufacturer and conversion‑kit specialist best known for mid‑1980s Bally retrofit kits—most notably the 301/Bulls Eye, a solid‑state conversion released in 1986 that was designed to retrofit Bally electronic four‑player cabinets (excluding The Six Million Dollar Man and widebody titles). The company produced several small‑run machines and conversion kits under the Grand Products name beginning in 1986, and its 301/Bulls Eye and related Bally‑based conversion parts remain documented by pinball databases and collectors, with playfields, parts and restoration resources still traded on parts markets and enthusiast forums.
