ABSTRACT:
A gun for firing pellets using compressed gas having a breech, a hammer mechanism slidably mounted in the breech, which mechanism includes a hammer and a spring mounted to drive the hammer forwards when the gun is fired, and a trigger pivotally connected to the breech. A sear device having a front and a rear end is mounted on a sear pin in the breech. A sear spring biases the sear device so that the front end thereof pivots downwardly after the hammer is released. This sear device includes a sear detent slidably mounted in the front end. A small spring biases the sear detent to move to a forward position in order to be engageable by the trigger. The valve mechanism of the gun is mounted by a pin about which extends an elastomeric bumper. This bumper reduces shock loading on a top frame of the gun.
