Freeflow has always been a popular brand, even though some of their claims have raised eyebrows and controversy; offering performance and a life time warranty until closing their doors in 2005. Professional Paintball (Freeflow) is responsible for the Fulcrum, Boxxer, Millennium, Rhythm and Lotus lines, as well as the Lockout upgrade package (Lockout was the former pro factory team). Originally, Freeflow only offered custom offerings normally based on a single style. This was expanded into the Boxxer and later variants and the original style was renamed Fulcrum.
