The year 2003 brought several new markers and products from Smart Parts, due to a reshuffling of design engineers. The most notable new product from this time period was the Shocker 03 marker (whose name soon after became Shocker SFT). The Shocker SFT was a redesigned marker that used a single solenoid open bolt, cock valve operation capable of high firing speeds,small body size, but an average efficiency without a Smart Parts High Efficiency Bolt. Although this marker was given the name "Shocker", it actually shares virtually no design aspects with its namesake the older Shocker Sport. However, Smart Parts decided to call it the next-generation "Shocker" for marketing purposes, since the older Shockers were already discontinued.
