Abstract
An air gun toy which has a housing mounting a cylinder and a piston for compressing air to cause foam darts to be discharged. The air gun includes the piston, a first connector pivotally connecting a first link to the piston, a second connector pivotally connecting the first link to a second link, a third connector pivotally connecting the second link to housing, a main spring and a trigger. When the piston reaches its forward position, the first, second and third connectors align in a linear configuration, like a toggle joint, to brace the piston and prevent piston bounce back.
