     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present disclosure relates generally to the field of firearms. More specifically, the present disclosure relates to a suppressor shielding system for a firearm. 
     2. Description of Related Art 
     A suppressor or silencer is a device that is typically attached to or an integral part of a barrel of a firearm or air gun. The suppressor acts to reduce the amount of noise and visible muzzle flash generated when a firearm is fired. Suppressors are typically constructed of a metal cylinder with internal baffles to reduce the sound of firing by slowing and cooling the rapidly expanding gases from the firing of a cartridge through a series of chambers. Because the propellant gases exits the suppressor over a longer period of time and at a greatly reduced velocity, a reduced noise signature is produced. 
     Typically, suppressors are integral to the firearm&#39;s barrel, directly threaded to the barrel of the firearm (via interaction of an internally threaded portion of the suppressor and an externally threaded portion of the exterior of the barrel), or are attached or coupled to a “quick-detach” flash hider or other muzzle device (which typically includes a locking mechanism that allows the suppressor to be quickly installed or removed from the firearm). 
     During normal operation of a suppressed firearm, as rounds are fired, the barrel, surrounding components, and suppressor typically heats up and can cause burns to a user, if touched. Additionally, the heat can create a distinct thermal signature. Ofttimes, a handguard surrounds the barrel so as to provide an air gap between the barrel and a surface that is typically contacted by the user. 
     Any discussion of documents, acts, materials, devices, articles, or the like, which has been included in the present specification is not to be taken as an admission that any or all of these matters form part of the prior art base or were common general knowledge in the field relevant to the present disclosure as it existed before the priority date of each claim of this application. 
     BRIEF SUMMARY OF THE INVENTION 
     Unfortunately, there is no current design that allows for each shielding of a suppressor, while providing a sufficient air gap to allow improved cooling of the suppressor. 
     These and other disadvantages and shortcomings of the prior art are overcome by the features and elements of the present disclosure, wherein the suppressor shielding system provides an improved heat shield element that can be easily attached or coupled to a firearm barrel or handguard. By providing improved heat shielding and cooling and by surrounding at least a portion of the suppressor and/or related components, there is a significant reduction to the thermal signature of the suppressor and/or the related components.

     DETAILED DESCRIPTION OF THE INVENTION 
     The foregoing and other objectives, features, and advantages of the invention will be more readily understood upon consideration of the following description of the invention taken in conjunction with the accompanying drawings. 
     For simplicity and clarification, the design factors and operating principles of the suppressor shielding system according to the presently disclosed systems, methods, and/or apparatuses are explained with reference to various exemplary embodiments of a suppressor shielding system according to the presently disclosed systems, methods, and/or apparatuses. The basic explanation of the design factors and operating principles of the suppressor shielding system is applicable for the understanding, design, and operation of the suppressor shielding system of the presently disclosed systems, methods, and/or apparatuses. It should be appreciated that the suppressor shielding system can be adapted to many applications where a suppressor shielding system can be used. 
     As used herein, the word “may” is meant to convey a permissive sense (i.e., meaning “having the potential to”), rather than a mandatory sense (i.e., meaning “must”). Unless stated otherwise, terms such as “first” and “second” are used to arbitrarily distinguish between the elements such terms describe. Thus, these terms are not necessarily intended to indicate temporal or other prioritization of such elements. 
     The term “coupled”, as used herein, is defined as connected, although not necessarily directly, and not necessarily mechanically. The terms “a” and “an” are defined as one or more unless stated otherwise. 
     Throughout this application, the terms “comprise” (and any form of comprise, such as “comprises” and “comprising”), “have” (and any form of have, such as “has” and “having”), “include”, (and any form of include, such as “includes” and “including”) and “contain” (and any form of contain, such as “contains” and “containing”) are used as open-ended linking verbs. It will be understood that these terms are meant to imply the inclusion of a stated element, integer, step, or group of elements, integers, or steps, but not the exclusion of any other element, integer, step, or group of elements, integers, or steps. As a result, a system, method, or apparatus that “comprises”, “has”, “includes”, or “contains” one or more elements possesses those one or more elements but is not limited to possessing only those one or more elements. Similarly, a method or process that “comprises”, “has”, “includes” or “contains” one or more operations possesses those one or more operations but is not limited to possessing only those one or more operations. 
     It should also be appreciated that the terms “suppressor shielding system”, “suppressor”, “heat shield”, “thermal barrier”, and “firearm” are used for basic explanation and understanding of the operation of the presently disclosed systems, methods, and/or apparatuses. Therefore, the terms “suppressor shielding system”, “suppressor”, “heat shield”, “thermal barrier”, and “firearm” are not to be construed as limiting the systems, methods, and/or apparatuses of the present disclosure. Thus, for example, the term “heat shield” is to be understood to broadly include any element that is able to at least partially shield radiating/transmitted heat or thermal energy. 
     For simplicity and clarification, the suppressor shielding system of the present disclosure will be described as being used in conjunction with an exemplary barrel and/or handguard. However, it should be appreciated that these are merely exemplary embodiments of the suppressor shielding system and are not to be construed as limiting the presently disclosed systems, methods, and/or apparatuses. Thus, the suppressor shielding system of the present disclosure may be utilized in conjunction with any barrel, handguard, or device. 
     In the form of the present disclosure chosen for purposes of illustration,  FIGS.  1 - 9    illustrate various exploded, partially exploded, and/or assembled views of certain exemplary elements, components, and/or aspects of an exemplary embodiment of a suppressor shielding system  100 .  FIGS.  10 - 19    illustrate various exploded, partially exploded, and/or assembled views of certain exemplary elements, components, and/or aspects of an exemplary embodiment of a suppressor shielding system  200 . 
     In illustrative, non-limiting embodiment(s) of the present disclosure, as illustrated in  FIGS.  1 - 9   , the suppressor shielding system  100  comprises at least some of a heat shield element  110 , a thermal barrier  118 , a heat shield mount  120 , and a mounting collar  130 . These elements interact with portions of an exemplary firearm, typically comprising a barrel  30  extending from an upper receiver  10  and a handguard  20  extending from the upper receiver  10  and surrounding at least a portion of the barrel  30 . 
     As illustrated, the heat shield element  110  comprises a substantially tubular portion of material, which extends, along a longitudinal axis, A L , from a heat shield element barrel end  111  to a heat shield element muzzle end  112 . A heat shield element aperture  114  is formed through the heat shield element  110  and is defined by one or more interior heat shield element side walls  113  forming an interior surface of the heat shield element  110 . 
     One or more heat shield fastener apertures  115  are formed through the heat shield element  110 , proximate the heat shield element muzzle end  112 . In various exemplary embodiments, a plurality of heat shield fastener apertures  115  are formed through the heat shield element  110 , at substantially equally spaced locations. 
     In certain exemplary embodiments, the heat shield element  110  is formed of an alloy or carbon fiber. However, the heat shield element  110  may be formed of various desired materials and is not limited to being formed of carbon fiber. 
     In certain exemplary embodiments, the heat shield element  110  also comprises two or more layers, attached or coupled together. The two or more layers may optionally be attached or coupled together, via one or more adhesive backed layers. One or more of the adhesive backed layers may optionally comprise a 3M™ Ultra High Temperature Adhesive Transfer Tape, such as, for example, 9082 &amp; 9085 UHT tape to hold the two or more layers in place. 
     A thermal barrier  118  is positioned or formed within at least a portion of a heat shield element aperture  114  of the heat shield element  110 . The thermal barrier  118  is included to slow down heat soaking of the parts or components. In certain exemplary embodiments, the thermal barrier  118  is formed of a ceramic or partially ceramic material. The thermal barrier  118  may comprise a portion of material attached or coupled, using mechanical fasteners and/or high temperature adhesives, to at least a portion of an interior heat shield element side walls  113  of the heat shield element  110 . Alternatively, the thermal barrier  118  may be sprayed or spray bonded to at least a portion of the interior heat shield element side walls  113  of the heat shield element  110 . 
     In certain exemplary, nonlimiting embodiments, the thermal barrier  118  may comprise one or more layers of a flexible plasma bonded ceramic or partially ceramic material. For example, the thermal barrier  118  may comprise one or more layers of Zircoflex, in the form of a thin alloy sheet of flexible plasma bonded zirconium ceramic and one or more layers formed of a flexible Aerogel sheet. The sheets of Zircoflex and/or Aerogel may be used individually or sandwiched together to at least a portion of an interior heat shield element side walls  113  of the heat shield element  110 . Currently, Zircoflex is available in three thicknesses, with better thermal protection in the thicker form. While any thickness of material can be utilized, a thicker form of the material is typically utilized in areas of higher heat. 
     It should also be appreciated that Zircoflex and/or Aerogel may optionally be utilized within the heat shield element  110 , as a thermal barrier  118 , and may also optionally be utilized within portions of the handguard  20 . 
     In exemplary embodiments in which the thermal barrier  118  is sprayed or spray bonded to at least a portion of the interior heat shield element side walls  113  of the heat shield element  110 , a zirconium ceramic or other materials may be plasma spray bonded or otherwise applied directly to a portion of the interior heat shield element side walls  113  of the heat shield element  110 . 
     The heat shield mount  120  extends, along a longitudinal axis, A L , from a heat shield mount barrel end  121  to a heat shield mount muzzle end  122 . A heat shield mount aperture  124 , defined by one or more interior heat shield mount side walls  123 , extends through the heat shield mount  120 . A mount engagement portion  126  extends from the heat shield mount barrel end  121 , toward the heat shield mount muzzle end  122 , and includes an internally threaded portion formed within a portion of the heat shield mount aperture  124 . A heat shield engagement portion  123  is formed in a portion of the heat shield mount  120 . The heat shield engagement portion  123  includes an outer surface shaped so as to be at least partially received within a portion of the heat shield element  110 , proximate the heat shield element barrel end  111  of the heat shield element  110 . 
     One or more corresponding heat shield mount fastener apertures  125  are formed in the heat shield engagement portion  123  of the heat shield mount  120 . In various exemplary embodiments, at least one heat shield mount fastener aperture  125  corresponds to each heat shield fastener aperture  115 , such that when the heat shield engagement portion  123  is appropriately positioned within the heat shield element  110 , a heat shield mount fastener aperture  125  is appropriately aligned with a heat shield fastener aperture  115 . In various exemplary embodiments, each heat shield mount fastener aperture  125  is internally threaded with internal threads that correspond to external threads of heat shield mount fasteners  129 . Thus, once appropriately aligned, a heat shield mount fastener  129  is able to be positioned through each heat shield fastener aperture  115  and threadedly inserted within an aligned heat shield mount fastener aperture  125 . In this manner, the heat shield element  110  can be appropriately aligned with and secured to the heat shield mount  120 . 
     The mounting collar  130  extends, along a longitudinal axis, A L , from a mounting collar barrel end  131  to a mounting collar muzzle end  132 . A mounting collar aperture  134  extends through the mounting collar  130 . One or more handguard attachment extensions  137  extend from the mounting collar barrel end  131  (away from the mounting collar muzzle end  132 ) and each handguard attachment extension  137  includes a mounting collar fastener aperture  135  formed therethrough. Each handguard attachment extension  137  and mounting collar fastener aperture  135  corresponds to a handguard fastener aperture  25  formed in the handguard  20 . 
     A mounting collar engagement portion  133  extends from the mounting collar muzzle end  132 , toward the mounting collar barrel end  131 . At least a portion of the mounting collar engagement portion  133  is externally threaded. The external threads of the mounting collar engagement portion  133  matingly correspond to the internal threads of the mount engagement portion  126 . 
     During attachment and/or use of certain exemplary embodiments of the suppressor shielding system  100 , a suppressor  190  is attached or coupled to the barrel  30 . In various exemplary embodiments, the suppressor  190  comprises a suppressor core  192 , a suppressor body  194 , and a suppressor end cap  196 . The suppressor  190  is positioned through the mounting collar aperture  134  and the handguard attachment extensions  137  of the mounting collar  130  are aligned with the handguard fastener apertures  25 , such that the mounting collar fastener apertures  135  are aligned with the handguard fastener apertures  25 . A mounting collar fastener  139  is positioned through each mounting collar fastener aperture  135  and threadedly attached or coupled to internal threads of the handguard fastener aperture  25 . In this manner, the mounting collar  130  is attached or coupled to the handguard  20 . 
     Once the mounting collar  130  is appropriately attached or coupled to the handguard  20 , the heat shield mount  120  is threadably attached or coupled to the mounting collar  130 , via interaction of the internal threads of the mount engagement portion  126  and the external threads of the mounting collar engagement portion  133 . Once appropriately threadedly attached, the heat shield element  110  and thermal barrier  118  surround at least a portion of the suppressor  190 . 
     In various exemplary embodiments, the heat shield element  110  extends beyond a terminal end of the suppressor  190  (or suppressor flash cap  198 ). 
     In certain exemplary embodiments, a counter tension O-ring  140  may be positioned between the mounting collar  130  and the heat shield mount  120 , so as to provide additional tension between the mounting collar  130  and the heat shield mount  120 , to counteract unwanted or counter rotation of the heat shield mount  120  relative to the mounting collar  130 .

     It should also be appreciated that Zircoflex and/or Aerogel may optionally be utilized within the heat shield element  210 , as a thermal barrier  218 , and may also optionally be utilized within portions of the handguard  20 . 
     In exemplary embodiments in which the thermal barrier  218  is sprayed or spray bonded to at least a portion of the interior heat shield element side walls  213  of the heat shield element  210 , a zirconium ceramic or other materials may be plasma spray bonded or otherwise applied directly to a portion of the interior heat shield element side walls  213  of the heat shield element  210 . 
     The heat shield mount  220  extends, along a longitudinal axis, A L , from a heat shield mount barrel end  221  to a heat shield mount muzzle end  222 . A heat shield mount aperture  224  extends through the heat shield mount  220 . A mount engagement portion  226  extends from the heat shield mount barrel end  221 , toward the heat shield mount muzzle end  222 , and includes one or more heat shield mount capture extensions  228 , extending at least partially into the heat shield mount aperture  224 . In various exemplary embodiments, each heat shield mount capture extension  228  extends from a terminal portion of a flexible finger formed within a portion of the mount engagement portion  226  of the heat shield mount  220 . A heat shield engagement portion  223  is formed in a portion of the heat shield mount  220 . The heat shield engagement portion  223  includes an outer surface shaped so as to be at least partially received within a portion of the heat shield element  210 , proximate the heat shield element barrel end  211  of the heat shield element  210 . 
     One or more corresponding heat shield mount fastener apertures  225  are formed in the heat shield engagement portion  223  of the heat shield mount  220 . In various exemplary embodiments, at least one heat shield mount fastener aperture  225  corresponds to each heat shield fastener aperture  215 , such that when the heat shield engagement portion  223  is appropriately positioned within the heat shield element  210 , a heat shield mount fastener aperture  225  is appropriately aligned with a heat shield fastener aperture  215 . In various exemplary embodiments, each heat shield mount fastener aperture  225  is internally threaded with internal threads that correspond to external threads of heat shield mount fasteners  229 . Thus, once appropriately aligned, a heat shield mount fastener  229  is able to be positioned through each heat shield fastener aperture  215  and threadedly inserted within an aligned heat shield mount fastener aperture  225 . In this manner, the heat shield element  210  can be appropriately aligned with and secured to the heat shield mount  220 . 
     The mounting collar  230  extends, along a longitudinal axis, A L , from a mounting collar barrel end  231  to a mounting collar muzzle end  232 . A mounting collar aperture  234  extends through the mounting collar  230 . The mounting collar aperture  234  is formed so as to allow at least a portion of the barrel  30  to pass therethrough. In various exemplary embodiments, the mounting collar aperture  234  includes a recessed portion, so as to allow a threaded portion of the barrel  30  to extend through the mounting collar aperture  234 , and a shoulder between the threaded portion and an exterior of the barrel  30  can be fitted at least partially within the recessed portion of the mounting collar aperture  234 .

Each mounting collar capture recess  236  is formed so as to allow at least a portion of a corresponding heat shield engagement portion  223  to be received at least partially therein. In various exemplary embodiments, each mounting collar capture recess  236  is formed so as to allow a heat shield engagement portion  223  to be urged within a portion of the mounting collar capture recess  236 . Then, rotational movement of the heat shield mount  220  relative to the mounting collar  230  allows the heat shield engagement portion  223  to be rotated within the mounting collar capture recess  236 . Once appropriately rotated within the mounting collar capture recess  236 , the heat shield engagement portion  223  engages a further recessed or detent to portion of the mounting collar capture recess  236  to further secure the heat shield mount  220  to the mounting collar  230 . 
     During attachment and/or use of certain exemplary embodiments of the suppressor shielding system  200 , the mounting collar  230  is positioned relative to the barrel  30  such that the externally threaded portion of the barrel  30  extends through the mounting collar aperture  234 . A muzzle device/suppressor mount  270  is then attached or coupled, via interaction of the external threads of the barrel  30  and internal threads of the muzzle device/suppressor mount  270 , so as to capture the mounting collar  230  between the barrel  30  and the muzzle device/suppressor mount  270 . In various exemplary embodiments, a timing shim  275  may be provided between the mounting collar  230  and the muzzle device/suppressor mount  270  so as to allow the muzzle device/suppressor mount  270  to be rotationally timed relative to the barrel  30 . 
     The suppressor  290  is then attached or coupled to the muzzle device/suppressor mount  270 . In various exemplary embodiments, the suppressor  290  comprises a suppressor core  292 , a suppressor body  294 , and a suppressor end cap  296 . 
     Once the suppressor  290  is appropriately attached or coupled to the muzzle device/suppressor mount  270 , the heat shield mount  220  is partially rotatably attached or coupled to the mounting collar  230 , via interaction of the heat shield engagement portion(s)  223  of the mount engagement portion  226  and the mounting collar capture recess(es)  236  of the mounting collar engagement portion  233 . Once appropriately attached or coupled, the heat shield element  210  and thermal barrier  218  surround at least a portion of the suppressor  290 . 
     In various exemplary embodiments, the heat shield element  210  extends beyond a terminal end of the suppressor  290 . 
     In certain exemplary embodiments, a flat tension spring  245  may be positioned between the mounting collar  230  and the heat shield mount  220 , so as to provide additional tension between the mounting collar  230  and the heat shield mount  220 , to counteract unwanted or counter rotation of the heat shield mount  220  relative to the mounting collar  230 .
