ABSTRACT:
A device, for releasing a locked trigger set by a set-trigger mechanism in a gun having a receiver, a bolt loosely inserted in the receiver, and a bolt handle for rotating and reciprocating the bolt so as to load a bullet and set in a fire-enabling state, includes an abutting portion formed on the bolt handle, and a release link positioned for contact with the abutting portion and a trigger in accordance with a rotational movement of the bolt handle. The trigger locked by the set-trigger mechanism is released when the bolt handle is rotated up to a fire-disabling position, causing the abutting portion to push the release link against the trigger to unlock it. With this construction above, when the bolt handle is in the fire-disabling state, the trigger can never be in the locked position, which enables a safe and secure release of the locked trigger and safe bullet loading and/or removal.
