Fire Control Assembly

Abstract

In some embodiments, a fire control assembly comprises a trigger rotatable about a trigger axis and a hammer rotatable about a hammer axis. The trigger comprises a trigger sear. The hammer comprises a hammer sear. The trigger sear contacts the hammer sear at a sear engagement location. A reference triangle extending between the trigger axis, the hammer axis and the sear engagement location comprising a sear location interior angle greater than 130 degrees.

         7 . The fire control assembly of  claim 6 , the trigger comprising a first width portion and a second width portion, the first width portion comprising the trigger sear, the second width portion comprising the stop. 
     
     
         8 . The fire control assembly of  claim 1 , the hammer comprising a first portion and a second portion, the first portion comprising a strike face and a disconnector engagement surface, the second portion comprising the hammer sear and the catch. 
     
     
         9 . The fire control assembly of  claim 8 , the first portion located to a first side of a reference plane that intersects the hammer axis and the trigger axis. 
     
     
         10 . The fire control assembly of  claim 1 , the hammer comprising a first rotational position in the first orientation and a second rotational position in the second orientation, the hammer comprising a third rotational position wherein the hammer is configured to strike a firing pin. 
     
     
         11 . The fire control assembly of  claim 10 , wherein the second rotational position comprises an intermediate position located between the first rotational position and the third rotational position. 
     
     
         12 . The fire control assembly of  claim 1 , comprising a disconnector arranged to engage the hammer. 
     
     
         13 . The fire control assembly of  claim 1 , the trigger sear contacting the hammer sear at a sear engagement location, a reference triangle extending between the trigger axis, the hammer axis and the sear engagement location comprising a sear location interior angle greater than 120 degrees. 
     
     
         14 . A fire control assembly comprising:
 a trigger rotatable about a trigger axis, the trigger comprising a trigger sear;   a trigger spring arranged to bias the trigger in a first direction about the trigger axis;   a hammer rotatable about a hammer axis, the hammer comprising a hammer sear;   a hammer spring arranged to bias the hammer in a second direction about the hammer axis;   the trigger sear contacting the hammer sear at a sear engagement location, a reference triangle extending between the trigger axis, the hammer axis and the sear engagement location comprising a sear location interior angle greater than 130 degrees.   
     
     
         15 . The fire control assembly of  claim 14 , wherein a hammer sear radial distance is greater than a trigger sear radial distance. 
     
     
         16 . The fire control assembly of  claim 14 , wherein a hammer sear radial distance is at least 1.5 times a trigger sear radial distance.
