Multiple function paintball marker bolt

Abstract

A paintball marker using a lightweight bolt design suing a composite bolt structure with a light weight body and precision sear release edge adapted for consistent sear over the life of the marker. The composite bolt structure also has a spring retention end with a sear access slot and sear retraction ramp for guiding the sear to the precision release edge.

1 . A breech bolt apparatus for a paintball marker using a retractable sear to engage the breech bolt, the breech bolt comprising: 
 a main body having a sear catch edge distally positioned from a back end of the main body, the main body defining a sear access slot extending from the back end towards the sear catch edge.    
   
   
       2 . The apparatus of  claim 1 , the main body further defining a sear retraction ramp at an internal end of the sear access slot.  
   
   
       3 . The apparatus of  claim 1 , the main body further defining a rotational alignment structure, wherein the rotational control structure is used to control the alignment of the sear access slot with the retractable sear.  
   
   
       4 . The apparatus of  claim 2 , the main body further defining a rotational alignment structure, wherein the rotational alignment structure is used to control the alignment of the sear access slot with the retractable sear.  
   
   
       5 . The apparatus of  claim 3 , the rotational alignment structure comprising: 
 a guide extension outwardly projecting from the main body.    
   
   
       6 . The apparatus of  claim 4 , the rotational alignment structure comprising: 
 a guide extension outwardly projecting from the main body.    
   
   
       7 . The apparatus of  claim 5 , the main body having a central axis, the guide extension comprising a fin having a length aligned with the axis of the main body.  
   
   
       8 . The apparatus of  claim 6 , the main body having a central axis, the guide extension comprising a fin having a length aligned with the axis of the main body.  
   
   
       9 . The apparatus of  claim 1 , the sear catch edge comprising: 
 a precision release insert adapted to consistently engage and disengage the retractable sear.    
   
   
       10 . The apparatus of  claim 2 , the sear catch edge comprising: 
 a precision release insert adapted to consistently engage and disengage the retractable sear.    
   
   
       11 . The apparatus of  claim 3 , the sear catch edge comprising: 
 a precision release insert adapted to consistently engage and disengage the retractable sear.    
   
   
       12 . The apparatus of  claim 4 , the sear catch edge comprising: 
 a precision release insert adapted to consistently engage and disengage the retractable sear.    
   
   
       13 . The apparatus of  claim 5 , the sear catch edge comprising: 
 a precision release insert adapted to consistently engage and disengage the retractable sear.    
   
   
       14 . The apparatus of  claim 6 , the sear catch edge comprising: 
 a precision release insert adapted to consistently engage and disengage the retractable sear.    
   
   
       15 . The apparatus of  claim 7 , the sear catch edge comprising: 
 a precision release insert adapted to consistently engage and disengage the retractable sear.    
   
   
       16 . The apparatus of  claim 8 , the sear catch edge comprising: 
 a precision release insert adapted to consistently engage and disengage the retractable sear.    
   
   
       17 . A breech bolt apparatus for a paintball marker using a retractable sear to engage the breech bolt, the breech bolt comprising: 
 a main body defining a sear catch edge distally positioned from a back end of the main body and a rotational alignment structure, wherein the rotational control structure is used to control the alignment of the sear catch edge with the retractable sear.    
   
   
       18 . The apparatus of  claim 17 , the rotational alignment structure comprising: 
 a guide extension outwardly projecting from the main body.    
   
   
       19 . The apparatus of  claim 17 , the sear catch edge comprising: 
 a precision release insert adapted to consistently engage and disengage the retractable sear.    
   
   
       20 . A breech bolt apparatus for a paintball marker using a retractable sear to engage the breech bolt, the breech bolt comprising: 
 a main body having a sear catch edge distally positioned from a back end of the main body, the sear catch edge including a precision release insert adapted to consistently engage and disengage the retractable sear.
