ABSTRACT:
A trigger assembly for firearms which is externally adjustable to change trigger pull forces for both hunting and competition shooting, and which includes safety features for preventing inadvertant discharge. The trigger assembly is particularly adaptable for use with Mauser-type, bolt-action firearms and includes an over-center linkage mechanism which is geometrically adjustable to vary the pull force of the trigger piece. The over-center linkage mechanism includes a rotatable lever operably connected to the trigger piece, and a collapsible block pivotally coupled to the lever. The block and lever are alignable in supporting relation to the striker locking arm, which in turn holds the striker cocked. The relative alignment of the block and lever determines the amount of trigger pull forces required with the linkage mechanism in supporting engagement with the striker lock arm. Trigger piece movement effects rotation of the lever, pivotal collapse of the block and corresponding movement of the striker lock arm. A safety mechanism is provided to prevent unintentional pivotal collapse of the block.
