Tippmann is a manufacturer of paintball markers and paintball equipment, including military simulation kits. Originally a family owned business run from Fort Wayne, Indiana, in 2004 Dennis Tippmann Sr. sold a majority ownership stake to Summit Partners, a private equity firm. Tippmann designed the first automatic marker, the use of refillable air systems in place of 12 gram cartridges, the "Cyclone Feed" system, the "Flatline" barrel, and the Tippmann C-3, the first propane-powered marker.
