Skip Swift, of Swift Line Industries was one of the original East Coast Sniper 2 and Autococker innovators in the early 1990s. In the years after the introduction of the Autococker he worked on Bob Long and the Ironmen's paintball guns. He also produced parts and accessories in the early 1990s out of Connecticut.
