The Bushmaster series marker was released to the public in 1998. It's name, Bushmaster, was derived from a scarcely known snake; the Bushmaster is a venemous snake which lurks in bushes and shadows and attacks it's prey with total secrecy. The referance to the snake means that the Bushmaster paintball marker will sneak up on you and you wont know until it's too late.
The Bushmaster production line has been shut down since late 2004.
