     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present disclosure relates generally to the field of firearms and is particularly directed to improved interchangeable safety selectors for firearms, such as the AR-15, M4, and the like. 
     2. Description of Related Art 
     It is well known that most modern firearms are provided with a safety selector, which includes a lock member mounted within a portion of the firearm and movable between a “SAFE” position, in which the lock member blocks movement of a portion of the firearm&#39;s firing mechanism, such as the trigger or the hammer, and a “FIRE” position, which allows firing of the firearm. The lock member is actuated by a safety selector, mounted on the outside of the firearm, and connected to the lock member to move the lock member between the “SAFE” and “FIRE” positions. As manufactured, modern firearms are provided with a safety selector on the right side of the firearm, since most people are right-handed. 
     However, this is extremely inconvenient for left-handed people to operate. Also, the standard size of the safety selector lever for the AR-15 or M4 style firearm is about one inch in length and about ¼ inch in width and thickness. While this size makes the safety selector lever easy to locate and move, it, unfortunately, makes it very easy for the selector lever to catch the web of skin between the user&#39;s thumb and forefinger, which is painful and can interfere with actuation of the selector lever. Also, due to the size and bulk of the safety selector lever, many right-handed users find it annoying, since it underlies the trigger finger and can be uncomfortable. 
     Modifications have been proposed for replacing the manufacturer&#39;s safety mechanism with an interchangeable device having safety levers provided on both sides of the firearm to accommodate both left- and right-handed people. However, while certain modifications of the prior art provide safety selectors levers on both sides of the firearm, the modified safety levers are of the same dimensions as the manufacturer&#39;s safety selector levers. This merely multiplies the disadvantages mentioned above. 
     It has also been proposed to provide a shortened safety selector lever of approximately ½ inch. This reduces the likelihood of catching the user&#39;s skin, but does little to improve the bulkiness of the safety selector lever. Thus, none of the prior art safety selectors levers have been entirely satisfactory. 
     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.

     DETAILED DESCRIPTION OF THE INVENTION 
     For simplicity and clarification, the design factors and operating principles of the interchangeable safety selector levers according to this invention are explained with reference to various exemplary embodiments of an interchangeable safety selector levers according to this invention. The basic explanation of the design factors and operating principles of the interchangeable safety selector levers is applicable for the understanding, design, and operation of the interchangeable safety selector levers of this invention. It should be appreciated that the interchangeable safety selector levers can be adapted to many applications where a safety selector lever is necessary or desirable. 
     It should also be appreciated that the terms “safety selector”, “selector”, “lever”, and “firearm” are used for basic explanation and understanding of the operation of the systems, methods, and apparatuses of this invention. Therefore, the terms “safety selector”, “selector”, “lever”, and “firearm” are not to be construed as limiting the systems, methods, and apparatuses of this invention. 
     For simplicity and clarification, the interchangeable safety selector levers of this invention will be described as being used as a safety selector lever for an AR-15 or M4 style firearm. However, it should be appreciated that these are merely exemplary embodiments of the interchangeable safety selector levers and are not to be construed as limiting this invention. Thus, the interchangeable safety selector levers of this invention may be utilized in connection with any firearm or other device using a safety selector lever. 
     Throughout this application the word “comprise”, or variations such as “comprises” or “comprising” are used. 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. 
     Turning now to the drawing FIGS.,  FIGS. 1-15  illustrate certain elements and/or aspects of a first exemplary embodiment of the interchangeable safety selector  5 , according to this invention. In illustrative, non-limiting embodiment(s) of this invention, as illustrated in  FIGS. 1-15 , the interchangeable safety selector  5  comprise at least some of a lock member  12  and lever members  10 ,  20 , and/or  30 . 
     In the form of the present invention chosen for purposes of illustration,  FIG. 1  shows an exploded view of the interchangeable safety selector  5  removed from a firearm and comprising a lock member  12  and a pair of lever members  10  and  30  secured to opposing ends of the lock member  12  by suitable means, such as, for example, screws  18 . The lock member  12  is formed with a first portion  24  and a central recess  23 . The safety selector  5  is mounted in a firearm  8 , as seen in  FIG. 2 , and is rotatable between a “SAFE” position, as shown in  FIG. 2 , and a “FIRE” position, as shown in  FIG. 3 . 
     When the safety selector  5  is in the “SAFE” position, the first portion  24  of the lock member protrudes into the path of a movable member of the firearm&#39;s firing mechanism, such as a portion of the trigger or the hammer, not shown. However, when the safety selector  5  is rotated to the “FIRE” position, the recess  23  is positioned to allow free movement of the firing mechanism. 
     As shown, the lock member  12  has a projection  26  formed in each end of the lock member  12  and the lever members  10  and  30  are formed with recesses  28 , which mate with the projections  26  to ensure that the lock member  12  is rotated with the lever member  10  or  30 . 
     A detent recess  27  is formed in a portion of the lock member  12 . The recess  27  is capable of interacting with a detent of the firearm to limit rotational movement of the safety selector  5 . 
     Prior art safety selector levers have been attached solely by screws. However, repeated movement of the safety selector levers applies torque and sheering forces to the screws, which tends to strip the screws, allowing the safety selector lever to detach or fall off, rendering the safety inoperable and useless. The recessed design of the present invention provides a very solid attachment in which the screws  18  simply prevent the levers  10  and  30  from sliding along the recesses  28  and are subject to no additional stress as the levers  10  and  30  are rotated. 
     As issued, the safety selector  5  has a lever member, such as lever member  10 , located only on the left side of the firearm, which is inconvenient for left-handed shooters. Also, the standard lever member is approximately 1 inch in length and approximately ¼ inch in thickness. Unfortunately, this thickness can bear against the shooter&#39;s flesh and can be quite uncomfortable. Also, this length makes it quite easy for the lever member to snag the web of skin between the shooter&#39;s thumb and forefinger, which is extremely painful and, under combat conditions, can easily become infected, which can lead to serious or even fatal consequences. On the other hand, some shooters prefer a lever member of this length as being easy to locate and rotate. 
     To overcome these difficulties, the present invention provides lever members on each side of the firearm, such as levers  10  and  30 , as illustrated in  FIG. 1 . This makes the safety selector  5  conveniently operable by both right- and left-handed shooters. 
     Furthermore, as illustrated in  FIGS. 9-25 , the present invention provides a plurality of interchangeable lever members  10 ,  20 ,  30 ,  40 ,  50 ,  60 ,  70 , and  80  of different lengths, thicknesses, and configurations to allow the shooter to select lever members that are most satisfactory to the shooter. 
     For example,  FIGS. 4, 14, and 15  show a lever member  30 , which has a thickness of only approximately ⅛ inch. This thinner lever member is much more comfortable when underlying the shooter&#39;s skin and yet is equally easy to locate to arm or disarm the firearm. 
       FIGS. 5, 12, and 13  show a lever member  20 , which is only approximately ½ inch in length. This significantly reduces the likelihood of snagging the shooter&#39;s skin, which avoids the hazards associated with this problem. 
       FIGS. 16 and 17  show a lever member  40 , which combines certain of the features of the lever member  20  and the lever member  30 , Bye having a sickness of only approximately ⅛ inch and a length of only approximately ½ inch. 
       FIGS. 18 and 19  show a lever member  50 , which includes a protrusion or crank  35  that is spaced some distance from the recess  28 . 
       FIGS. 20 and 21  show a lever member  60 , which includes a protrusion or crank  35 , similar to that of lever member  50 . However, the protrusion or crank  35  of lever member  60  is spaced a shorter distance from the recess  28  than the protrusion or crank  35  of lever member  50 . 
       FIGS. 22 and 23  show a lever member  70 , which includes a notch or recess  37  formed proximate a terminal end of the lever member  70 . 
       FIGS. 24 and 25  show a lever member  80 . The lever member  80  includes a notch or recess  38  formed proximate a terminal end of the lever member  80 . When compared to lever member  70 , the lever member  80  is shorter in overall length and the notch or recess  38  is more sloped or scalloped, when compared to the notch or recess  37 . 
     As noted above, the lever members  10 ,  20 ,  30 ,  40 ,  50 ,  60 ,  70 , and  80  are interchangeable and may be mounted on each end of the lock member  12 . Furthermore, the lever member  10 ,  20 ,  30 ,  40 ,  50 ,  60 ,  70 , or  80  on one end of the lock member  12  may or may not match the lever member  10 ,  20 ,  30 ,  40 ,  50 ,  60 ,  70 , or  80  on the opposite end of the lock member  12 . 
     It should also be noted that the lever members  10 ,  20 ,  30 ,  40 ,  50 ,  60 ,  70 , and  80  are formed with a plurality of diagonal grooves  30  and/or vertical grooves  31 . These grooves serve to prevent the user&#39;s finger from slipping off the lever members  10 ,  20 ,  30 ,  40 ,  50 ,  60 ,  70 , and  80  and also serve to hold paint, which may be applied to the lever members  10 ,  20 ,  30 ,  40 ,  50 ,  60 ,  70 , and  80  as is often done in training. 
     In various exemplary embodiments, various components of the interchangeable safety selector  5  are substantially rigid and are formed of stainless steel. Alternate materials of construction of the various components of the interchangeable safety selector  5  may include one or more of the following: steel, aluminum, titanium, and/or other metals, as well as various alloys and composites thereof, glass-hardened polymers, polymeric composites, polymer or fiber reinforced metals, carbon fiber or glass fiber composites, continuous fibers in combination with thermoset and thermoplastic resins, chopped glass or carbon fibers used for injection molding compounds, laminate glass or carbon fiber, epoxy laminates, woven glass fiber laminates, impregnate fibers, polyester resins, epoxy resins, phenolic resins, polyimide resins, cyanate resins, high-strength plastics, nylon, glass, or polymer fiber reinforced plastics, thermoform and/or thermoset materials, and/or various combinations of the foregoing. Thus, it should be understood that the material or materials used to form the various components of the interchangeable safety selector  5  is a design choice based on the desired appearance and functionality of the interchangeable safety selector  5 . 
     It should be appreciated that certain elements of the interchangeable safety selector  5  may be formed as an integral unit (such as, for example, the lock member  12  and one or more of the lever members  10 ,  20 ,  30 ,  40 ,  50 ,  60 ,  70 , or  80 ). Alternatively, suitable materials can be used and sections or elements made independently and attached or coupled together, such as by adhesives, welding, screws, rivets, pins, or other fasteners, to form the various elements of the interchangeable safety selector  5 . 
     It should also be understood that the overall size and shape of the interchangeable safety selector  5  and the various portions thereof, the lock member  12 , and the lever members  10 ,  20 ,  30 ,  40 ,  50 ,  60 ,  70 , or  80 , is a design choice based upon the desired functionality and/or appearance of the interchangeable safety selector  5 . 
       FIGS. 26, 27, 28, 30, and 31  show alternative embodiments of the lock member  12 . As illustrated in  FIG. 26 , is the lock member  22  includes features similar to the lock member  12 , but includes alternately formed central recess  23  and first portion  24 . It should be appreciated that the formation of the central recess  23  and the first portion  24  allow the lock member to interact with different portions of the firearm&#39;s trigger mechanism at different points along the rotation of the lock member, thereby potentially providing, for example, a “SAFE” position, a semi-auto “FIRE” position, a burst “FIRE” position, and/or a full-auto “FIRE” position. 
     As further illustrated in  FIG. 26 , the detent recess  27  is formed to provide 90° of rotational movement of the lock member  22 . 
       FIG. 27  illustrates an exemplary lock member  32 . The lock member  32  includes features similar to the lock members  12  and  22 , but includes alternately formed central recess  23  and first portion  24 . 
       FIG. 28  illustrates an exemplary lock member  42 . The lock member  42  includes features similar to the lock member  22 , but includes a pin or projection  25  that can allow the lock member  42  to only be used with certain firearms having an appropriate keyway to allow the lock member  42 , having the projection  25 , to be installed in the firearm. 
     Furthermore, the detent recess  27  formed in the lock member  42  is formed so as to provide 50° of rotational movement of the lock member  42 , with detented stop points at 0° and 50°. Thus, utilizing the lock member  42 , a lever member, such as, for example lever member  10 , as illustrated in  FIG. 29 , is only rotated 50° (θ) to move from the “SAFE” position to the “FIRE” position. 
     It should be appreciated that by altering the length of the detent recess  27 , the degree of rotation (θ) for the lever member can be altered. 
       FIGS. 30 and 31  show alternate views of a lock member  52 . As illustrated, the detent recess  27  provides for 180° of rotation, with detented stop points at 0°, 50°, and 180°. 
       FIGS. 32 and 33  show alternate embodiments of a lock member  62  and  72 . The lock members  62  and  72  include at least some a central recess  23 , a first portion  24 , a detent recess  27 , and a pin or projection  25 . It should be appreciated that these elements correspond to and operate similarly to the central recess  23 , the first portion  24 , the detent recess  27 , and the pin or projection  25 , as described, with reference to lock members  12 - 52 . 
     However, as illustrated in  FIGS. 32 and 33 , the lock members  62  and  72  include projections  29  instead of projections  26 . As shown, the lock members  62  and  72  have a projection  29  formed in each end of the lock members  62  and  72  (defining a recess  29 ′) and the lever members  110 ,  120 ,  130 ,  140 ,  150 ,  160 ,  170 , and  180  each include a projection  128 , which mates with the projections  29  and recess  29 ′ to ensure that the lock member  62  or  72  is rotated with the lever member  110 ,  120 ,  130 ,  140 ,  150 ,  160 ,  170 , or  180 . 
     It should be appreciated that the characteristics of the lever members  110 ,  120 ,  130 ,  140 ,  150 ,  160 ,  170 , and  180  correspond to the characteristics of the lever members  10 ,  20 ,  30 ,  40 ,  50 ,  60 ,  70 , and  80 , respectively.
