The newlt designed trigger mechanism consisted basically of four major components, trigger, trigger pawl, sear trip, and sear. These, together with their operating springs were contained within a seperate pressed steel housing which was fitted to the receiver by menas of a front screw and rear pin. Hinged together the the sear was the ejector which was spring loaded and which rose up and contacted the cartridge head on the final rearwards movement of the bolt. The sear also doubled as a bolt stop engaging in a shallow depression in the underside of the bolt preventing complete withdrawal when the bolt was fully opened.
The let-off weight of the trigger could be adjusted by means of a screw set in the front of the trigger blade. The top of the trigger housed a second screw which controlled the creep or movement of the trigger; adjustment of this screw was sufficient to give a double pull action if required.
