     BACKGROUND 
     Description of the Related Art 
     A suppressor may be used to reduce the noise made during the discharge of a firearm. One example of a prior firearm suppressor is a housing that includes a series of baffles positioned within the housing. For example, the housing, also referred to as a can, may include a series of k-type baffles positioned within the can. The baffles are constructed to provide a series of chambers that permit the contraction and expansion of the gas created by the discharge of ammunition. Baffles include a central opening permitting a fired projectile to pass through the suppressor. The central portion of the baffles takes the brunt of the force of the gasses generated during the discharge of the firearm. Repeated use of the suppressor can damage the central portion of the baffles causing the suppressor to be ineffective or, if permitted, replacement one or more baffles of the suppressor. Accordingly, there is a need to provide firearm suppressor that may permit the replacement of only damaged portions of the baffles. Other drawbacks and disadvantages of present suppressor systems also exist.

     DETAILED DESCRIPTION 
       FIGS.  1 - 5    show an embodiment of a multi-core firearm suppressor  100 . The suppressor includes a housing  110  having a first end  111  and a second end  112 . A central main core  120  is positioned within the housing  110 . The central main core  120  includes a first end  121 , a second end  122 , and has a longitudinal centerline  125 . The central main core  120  includes a plurality of central baffle portions  123  that are positioned adjacent to the longitudinal centerline  125 . The central baffle portions  123  engage or interlock with baffle portions from a first side core  130  and a second side core  140  to form baffles within the housing  110  as discussed herein. The central baffle portions  123  include a projectile path  129  along the longitudinal centerline  125  to enable a projectile to pass through multi-core firearm suppressor  100 . 
     The multi-core firearm suppressor  100  includes a first side core  130  that is positioned within the housing  110 . The first side core  130  includes a first end  131  and a second end  132 . The first side core  130  is positioned between the housing  110  and a first side of the central main core  120 . The first side core  130  includes a plurality of first side baffle portions  133 . The first side core  130  also includes a portion  134  that engages the central main core  120  to help strengthen an enclosed entrance chamber  101  of the multi-core firearm suppressor  100 . 
     The multi-core firearm suppressor  100  includes a second side core  140  that is positioned within the housing  110 . The second side core  140  includes a first end  141  and a second end  142 . The second side core  140  is positioned between the housing  110  and a second side of the central main core  120 . The second side core  140  includes a plurality of second side baffle portions  143 . The second side core  140  also includes a portion that engages the central main core  120  to help strengthen an enclosed entrance chamber  101  of the multi-core firearm suppressor  100 . 
     When the central main core  120 , first side core  130 , and second side core  140  are positioned within the housing  110 , the first side baffle portions  133  and the second side baffle portions  143  each engage the central baffle portions  123  to form baffles within the housing  110  that include a projectile path  129  along the longitudinal centerline  125 . The combined baffles may be used to suppress the sound of the discharge of a firearm connected to the multi-core firearm suppressor  100 . The combined baffles cause the expansion and contraction of the gas from the discharge of the firearm that reduces the sound of the discharge as would be appreciated by one of ordinary skill in the art having the benefit of this disclosure. 
     During the discharge of the firearm connected to the multi-core firearm suppressor  100 , the central baffle portions  123  of the combined baffles typically take the brunt of the force from the high-pressure gasses from the discharge. Thus, the central baffle portions  123  may become damaged sooner than either of the side baffle portions  133 ,  143 . The multi-core firearm suppressor  100  enable only the central main core  120  to be replaced if the side baffle portions  133 ,  143  are not damaged. Further, the multi-core design may enable the central main core  120  to be comprised of a different material than the side cores  130 ,  140 . For example, the central main core  120  may be comprised of a stronger and/or tougher material than the side cores  130 ,  140 . The design of the multi-core firearm suppressor  100  also may enable each component to be created by various formed of manufacturing such as, but not limited to, machining  3 D printing, casing, metal injection molding, and plastic injection molding. The design of the multi-core firearm suppressor  100  may enable one component to be manufactured by a first process and a second component to be manufactured by a second different process. 
     The central main core  120  includes a port  124  at the first end  121 . As shown in  FIGS.  39 - 41   , the port  124  is configured to connect to a gas block  510  connected to a barrel  500  of a firearm (not shown). The port  124  is in fluid communication with the enclosed entrance chamber  101  of the multi-core firearm suppressor  100 . A tube  520 , or other means, may connect the port  124  of the central main core  120  and the gas block  510  of a connected firearm. The gas block  510  is connected to the passage  501  of the barrel via a port  502  in the barrel  500  and a port  511  in the gas block. The gas block  510  is connected to the receiver of the firearm via a tube  530 , or other means, as would be appreciated by one of ordinary skill in the art having the benefit of this disclosure. Integration of the multi-core firearm suppressor  100  with the firearm system may extend dwell time by creating an interaction between the firearm&#39;s gas system and the enclosed entrance chamber  101  of the multi-core firearm suppressor  100 . The gas system of the firearm may vent gas into the enclosed entrance chamber  101  of the multi-core firearm suppressor  100  so that the firearm doesn&#39;t start to unlock until the enclosed entrance chamber  101  is pressurized from the bullet passing though and gasses from the firearm being released in the multi-core firearm suppressor  100 . This equalizes the pressure in the firearm&#39;s gas system and the vent, causing the firearm to cycle, which may keep the firearm cleaner and/or improve the sound suppressing function of the multi-core firearm suppressor  100  by keeping the action of the firearm in battery longer.
