A hand held pneumatic gun having an airway arranged to be coupled to a source of compressed air, the airway communicating with an air chamber via a trigger valve,
- a detachable breech coaxially supported by a support ring pivotally secured to the body of the gun to move from an open position where the breech can be detached to a closed position where the breech is sealed against the air chamber to allow, on actuation of the trigger valve passage of compressed air into the breech.
A pneumatic gun according to claim wherein the trigger valve is spring loaded to a neutral position to prevent air reaching the air chamber and on actuation the trigger valve allows air to flow to the air chamber.
