     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     With reference now to the drawings, and in particular to FIGS. 1 through 3 thereof, a new quick detachable gun barrel assembly embodying the principles and concepts of the present invention and generally designated by the reference numeral  10  will be described. 
     As best illustrated in FIGS. 1 through 3, the quick detachable gun barrel assembly  10  generally comprises a barrel coupling assembly being adapted to removably attach to a chamber  28  of a gun  27 , in particular, a paint gun. The barrel coupling assembly includes a tubular main portion  11 , and also includes a collar  16  being conventionally attached about the tubular main portion  11 , and further includes a threaded shaft  18  being conventionally attached to the tubular main portion  11  and being adapted to thread into the chamber  28  the gun  27 , and also includes a retainer ring  29  being conventionally disposed in the tubular main portion  11 . The tubular main portion  11  has open first and second ends  12 , 13  and a bore  14  extending therethrough and being defined by a wall which has an annular groove  15  disposed therein. The collar  16  is conventionally disposed near the second end  13  of the tubular main portion  11  and has a plurality of notches  17  being circumferentially-spaced about and being disposed in an exterior of a wall thereof for allowing a user to easily grasps the collar  16  with one&#39;s fingers. The threaded shaft  18  has a bore  19  extending therethrough and which is in alignment with the bore  14  of the tubular main portion  11 . The shaft  18  is conventionally attached at the open first end  12  of the tubular main portion  11 . The retainer ring  29  is seated-in the annular groove  15 . 
     An elongate barrel member  20  is detachably attached to the barrel coupling assembly. The elongate barrel member  20  has open first and second ends  21 , 22 , and also has a bore  30  extending therethrough, and further has a first end portion  23  which is securely and removably received in the bore  14  of the tubular main portion  11  through the open second end  13  thereof. The first end portion  23  of the elongate barrel member  20  has an annular recessed portion  24  and has an annular channel  25  being disposed in an exterior of a wall of the annular recessed portion  24  and removably receiving the retainer ring  29  upon the first end portion  23  of the elongate barrel member  20  being securely received in the tubular main portion  11 . The elongate barrel member  20  further includes a plurality of notches  26  being circumferentially-spaced about and being disposed in an exterior of a wall of the elongate barrel member  20  at the second end  22  thereof. 
     In use, the user would thread the shaft  18  into the open end of the chamber  28  of the paint gun  27 , and would then insert the first end portion  23  of the elongate barrel member  20  into the open second end  13  of the tubular main portion  11  until the retainer ring  29  is seated in the annular channel  25  of the annular recessed portion  24  of the elongate barrel member  20 . To remove the elongate barrel member  20 , the user simply grasps the elongate barrel member  20  and pulls it out of the tubular main portion  11 . 
     As to a further discussion of the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided. 
     With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention. 
     Therefore, the foregoing is considered as illustrative only of the principles of the quick detachable gun barrel assembly. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
