ABSTRACT:
A firing mechanism for an air weapon in which air is compressed in a cylinder and expelled through a discharge port in the cylinder to propel a projectile along a barrel by a piston executing a firing stroke. The mechanism comprises a piston slidably located within a cylinder with the crown of the piston facing towards the discharge port. A spring urges the piston towards the discharge port. A bobbin is located behind the piston crown, which is axially movable with the piston during at least a portion of the firing stroke and is axially movable relative to the piston at the end of the firing stroke.
