AK Fire Control Mechanism

Abstract

In some embodiments, a fire control mechanism comprises a hammer, a trigger and a safety. The hammer is rotatable about a hammer axis. The trigger is rotatable about a trigger axis and arranged to contact the hammer. The safety is arranged to interfere with rotation of the trigger. The safety comprises a second portion moveable with respect to a first portion.

1 . A fire control mechanism comprising:
 a hammer rotatable about a hammer axis;   a trigger rotatable about a trigger axis, the trigger arranged to contact the hammer; and   a safety arranged to interfere with rotation of the trigger, the safety comprising a second portion moveable with respect to a first portion.   
     
     
         2 . The fire control mechanism of  claim 1 , the safety arranged to rotate about a safety axis. 
     
     
         3 . The fire control mechanism of  claim 2 , wherein a distance between the safety axis and the second portion changes as the second portion is moved with respect to the first portion. 
     
     
         4 . The fire control mechanism of  claim 1 , the second portion comprising screw threads. 
     
     
         5 . The fire control mechanism of  claim 4 , the first portion comprising a threaded cavity. 
     
     
         6 . The fire control mechanism of  claim 1 , the second portion comprising a set screw. 
     
     
         7 . The fire control mechanism of  claim 1 , the first portion comprising a bore, the bore providing access to the second portion. 
     
     
         8 . A fire control mechanism comprising:
 a hammer rotatable about a hammer axis;   a trigger rotatable about a trigger axis, the trigger arranged to contact the hammer; and   a safety arranged to interfere with rotation of the trigger, the safety comprising a supported portion, the safety comprising a bevel adjacent to the supported portion.   
     
     
         9 . The fire control mechanism of  claim 8 , the bevel comprising a cross-section smaller than a cross-section of the supported portion. 
     
     
         10 . The fire control mechanism of  claim 9 , the supported portion and the bevel sharing an edge. 
     
     
         11 . The fire control mechanism of  claim 8 , the safety comprising a flange adjacent to the supported portion. 
     
     
         12 . The fire control mechanism of  claim 11 , the flange comprising a cross-section larger than a cross-section of the supported portion. 
     
     
         13 . The fire control mechanism of  claim 12 , the bevel and flange located on opposite sides of the supported portion. 
     
     
         14 . The fire control mechanism of  claim 8 , the supported portion comprising a first supported portion, the safety comprising a second supported portion and a second bevel adjacent to the second supported portion. 
     
     
         15 . The fire control mechanism of  claim 14 , comprising a housing arranged to support the first supported portion and the second supported portion, the second bevel oriented outside the housing. 
     
     
         16 . A fire control mechanism comprising:
 a hammer rotatable about a hammer axis;   a trigger rotatable about a trigger axis, the trigger arranged to contact the hammer;   a disconnector rotatable about the trigger axis; and   a trigger pin arranged to support the trigger and the disconnector, the trigger pin comprising a bevel.   
     
     
         17 . The fire control mechanism of  claim 16 , the bevel located at an end of the trigger pin. 
     
     
         18 . The fire control mechanism of  claim 16 , the trigger pin contacting the trigger. 
     
     
         19 . The fire control mechanism of  claim 18 , the trigger pin contacting the disconnector. 
     
     
         20 . The fire control mechanism of  claim 16 , the trigger comprising a bevel.
