In 1990, Smart Parts produced their first in-house marker. Called the Boss, the Smart Parts pump marker featured a spiral ported barrel and a 'shoebox' style body (which would be mirrored in their first electronic gun design); The Boss was targeted at high-end woodsball tournament players but was not well-received, being considered to be too heavy and too large (when compared to offerings such as the Carter Comp or LAPCO Grey Ghost). The Boss was withdrawn from the market and Smart Parts concentrated on producing customized versions of other manufacturer's markers until 1996 when Smart Parts began selling their first electronic marker, the Shocker. This marker was manufactured by a company called pneuVentures, but sold exclusively through Smart Parts. This original Shocker was a dual-solenoid, closed bolt, hammerless marker that was large, heavy, inefficient, and could fire a maximum speed of 9 shots per second. A couple thousand of these were sold over the course of its lifetime. Other companies that had been working on their own electronic markers also released them about the same time (WDP Angel - 1996, Brass Eagle Rainmaker - 1997).
