Claims17
A drop-in trigger unit for a firearm, the firearm having a trigger pocket in a lower receiver that is configured to receive the drop-in trigger unit, where the trigger pocket includes a trigger window in the lower receiver that is at least partially defined by one or more receiving surfaces:
- the drop-in trigger unit comprising:
- a trigger housing that accommodates the trigger unit, the trigger housing including one or more trigger housing protrusions formed laterally on the trigger housing in a transverse direction, each trigger housing protrusion having protrusion side surfaces that are complementary to the receiving surfaces of the trigger window;
- wherein the trigger housing is configured to be installed in the trigger pocket, with the protrusion side surfaces of the trigger housing protrusions cooperating with the receiving surfaces of the trigger window to guide the trigger housing into position within the trigger pocket and hold the trigger housing therein, so that upon installation the protrusion side surfaces of the trigger housing protrusions will contact the receiving surfaces of the trigger window in order to seal an interior of a lower part of the lower receiver from external environmental influences.
A lower receiver of a firearm, the lower receiver defining a trigger pocket for receiving a modular drop-in trigger unit, where the trigger unit is arranged in a trigger housing and the trigger pocket includes lateral guides configured to support the trigger housing and secure it within the trigger pocket, where the trigger pocket includes a trigger window in the lower receiver that is at least partially defined by one or more receiving surfaces:
- the drop-in trigger unit comprising:
- the trigger housing that accommodates the trigger unit, the trigger housing including one or more trigger housing protrusions formed laterally on the trigger housing in a transverse direction, each trigger housing protrusion having protrusion side surfaces that are complementary to the receiving surfaces of the trigger window;
- wherein the trigger housing is configured to be installed in the trigger pocket, with the protrusion side surfaces of the trigger housing protrusions cooperating with the receiving surfaces of the trigger window to guide the trigger housing into position within the trigger pocket and hold the trigger housing therein, so that upon installation the protrusion side surfaces of the trigger housing protrusions will contact the receiving surfaces of the trigger window in order to seal an interior of a lower part of the lower receiver from external environmental influences.
A firearm, comprising:
- a breech;
- an upper receiver;
- and
- a lower receiver, wherein the lower receiver defines a trigger pocket for receiving a modular drop-in trigger unit, where the trigger unit is arranged in a trigger housing and the trigger pocket includes lateral guides configured to support the trigger housing and secure the trigger housing within the trigger pocket, where the trigger pocket includes a trigger window in the lower receiver that is at least partially defined by one or more receiving surfaces;
- wherein when the modular drop-in trigger unit is installed in the trigger pocket the modular drop-in trigger unit is secured from movement from above by the upper receiver and/or the breech, and
- wherein the drop-in trigger unit comprising:
- the trigger housing that accommodates the trigger unit, the trigger housing including one or more trigger housing protrusions formed laterally on the trigger housing in a transverse direction, each trigger housing protrusion having protrusion side surfaces that are complementary to the receiving surfaces of the trigger window;
- wherein the trigger housing is configured to be installed in the trigger pocket, with the protrusion side surfaces of the trigger housing protrusions cooperating with the receiving surfaces of the trigger window to guide the trigger housing into position within the trigger pocket and hold the trigger housing therein, so that upon installation the protrusion side surfaces of the trigger housing protrusions will contact the receiving surfaces of the trigger window in order to seal an interior of a lower part of the lower receiver from external environmental influences.
