       BACKGROUND OF THE INVENTION 
       [0002]    Traditionally, when aiming a shouldered firearm, the shooter brings the gun to the shoulder and tilts and rotates the head into the stock to enable the shooter to see down the barrel mounted sight to the intended target. This movement prohibits the shooter from squaring his head vertically and horizontally with the target. The shooter forfeits the natural stance of directly facing the target and of keeping the head fixed and still in the gun mount. This extra movement leaves room for increased error. Additionally, it has been long understood that the less movement required by the shooter while acquiring the sight results in greater accuracy when shooting. It is also widely accepted that the better the gun fits the user, the better it lends itself to greater comfort, also leading to greater accuracy when shooting. 
         [0003]    This invention, which was created for use in hunting and sporting, allows the gun to rise and rotate in front of the shooter&#39;s eye by a rotation of the stock thereby letting the shooter align the eye with the sight of the gun without having to tilt or rotate the head. This allows the shooter to directly face the target, keeping the head still while mounting the gun, leading to minimal movement, greater accuracy, and a natural gun mount. This is of special advantage to those who shoot with both eyes open in that it allows for an accurate depth of perception. This invention can be incorporated into the design of any shouldered firearm in which the stock is held against shoulder and the stock is lower than the barrel. Existing stock butts may also be adapted to feature this modification by attaching the aftermarket adjustable rotating recoil shoulder pad. 
       BRIEF SUMMARY OF THE INVENTION 
       [0004]    It is a benefit of the present invention to allow the barrel and sighting device to remain elevated above the stock butt, and provides a means whereby the firing mechanism, barrel, and sighting device can be set at different degrees to the left or to the right of the vertical center of the stock butt. 
         [0005]    This invention gives the user the advantage of the barrel and sighting mechanism being directly placed in front of the user&#39;s eye while the head is substantially perpendicular to the target 
         [0006]    This invention gives the shooter the further benefit of having both eyes perpendicular with the target, allowing equal depth of perception; this is useful to all shooters, but gives the greatest advantage to the shooter that shoots with both eyes open. 
         [0007]    Another benefit of this invention is very little to no head movement in the gun mount. 
         [0008]    A further benefit of this invention is lengthening and shortening the stock butt. 
         [0009]    Yet another benefit of this invention is raising and lowering the shoulder recoil pad. 
         [0010]    Still a further benefit of this invention is adjusting the sighting bead to maintain top center when the firing mechanism and barrel are offset at different degrees.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0017]    This description depicts only typical embodiments of the invention, and is not intended to be limiting of its scope. 
         [0018]    As seen in  FIG. 1 , a shouldered firearm includes a second member of adjustable gun butt  4 , with a large opening  5  and then a reduced opening  6 . The gun butt leads to the forward portion of the first member of the adjustable gun butt  7 , to which this invention primarily applies. 
         [0019]    Spacers  9   abc  fit into the gun butt opening  5  to allow the shooter to adjust the length of the stock  7 . The fastener  11  travels through the reduced opening  6  of gun butt  4  and the spacer openings  10   abc  as needed, and fastens into the threaded opening  8  in the rearward portion of the first member of the adjustable gun butt  7 . When the fastener  11  is loosened, the first member of adjustable gun butt  7  can be adjusted into the desired position. When the fastener  11  is tightened, it holds the second member of the adjustable gun butt  4  and the first member of adjustable gun butt  7  securely together. 
         [0020]    Further,  FIG. 1  displays the adjustable recoil shoulder pad  12  fastened to the rearward portion of the second member of adjustable gun butt  4 . Elongated vertical openings  19   ab  in the recoil shoulder pad  12  allow the recoil shoulder pad to be adjusted upward or downward to suit the shooter, and also allow fasteners  20   ab  traveling through the recoil shoulder pad  12  to fasten into the second member of the adjustable gun butt  4 . This allows the recoil shoulder pad  12  to be adjusted downward, thereby raising the gun to the shooter&#39;s desired position. 
         [0021]      FIG. 2  displays a rear view of a shouldered firearm, showing the forward portion of the first member of adjustable gun butt  7 , the rearward portion of the firing mechanism  18  pivoted counterclockwise about an axis, the sighting base  14 , and the sighting bead  15  pivoted clockwise about an axis. Once adjusted, the rotating portion is fixed in place by fasteners  11 . As pictured, the rotation has caused the firing mechanism  18  the barrel  13 , and the sighting bead  15  to be located to the left of the stock, shown by the broken lines of  16   ab . The sighting bead  15  is attached to a base  14 , which allows for adjustment to accommodate the rotation of the firing mechanism  18  and the barrel  13 . 
         [0022]      FIG. 2  also displays the recoil shoulder pad  12 , along with the two elongated vertical slots  19   ab , which allow for an upward and downward adjustment of the recoil shoulder pad  12 , and the fasteners  20   ab , which hold the pad in the desired position. This allows the shooter to not have to lower the head by raising the gun  14  and sighting device  15  in front of shooter&#39;s eye. The horizontal distance between the sighting bead  15  and the gun butt  4  is depicted  16   ab . The elevated distance of the sighting bead above the adjustable stock is also depicted  17   ab . The fastener  11  is the center point of rotation. 
         [0023]      FIG. 3  depicts the side view of a shouldered firearm, including a sectional view of the second member of the adjustable gun butt  4 . This view displays the first member of adjustable gun butt  7  and the spacer  9   a  for adjusting the stock length. It also displays the mechanism for fastening the stock in place once pivoted: the threaded opening for the fastener  8 , and the fastener  11 . The second member of the adjustable gun butt  4  houses the rearward portion of the first member of the adjustable gun butt  7 . The forward portion of the first member of the adjustable gun butt  7  is fasted and fixed in place to the firing mechanism  18 . The adjustable recoil shoulder pad  12  is displayed. Also pictured are the gun barrel  13  and the firing mechanism  18 . In this picture the recoil shoulder pad  12  is fixed in place to the second member of the adjustable gun butt  4 . 
         [0024]    Displayed in  FIG. 4  is a topical view of a shouldered firearm with a manufactured, fixed stock, held in firing position. The forward portion of the pivoted fixed stock  7   a  is fixed in the pivoted position. The center of the target  21  is aligned with the optical path of the left  22 L and right  22 R eyes. The shooter&#39;s head is substantially perpendicular to the target  23 , and the firing mechanism  18 , while the barrel  13 , and sighting bead  15  are in front of the shooter&#39;s eye. 
         [0025]      FIG. 5  depicts the after market pivoted recoil shoulder pad  28 . The firing mechanism  18  has been pivoted to the left of the recoil shoulder pad  28 , is substantially vertical and is in firing position. The sighting base  14 , which is attached to upper portion of gun barrel  13  (visible in  FIG. 6 ) and the adjustable sighting bead  15  which is attached to sighting base  14 , is located to the left of recoil shoulder pad. It shows the offsetting of the sighting bead from the adjustable recoil shoulder pad  28 . Additionally,  16   b  broken lines show the offsetting of the firing mechanism  18 , sighting base  14 , and sighting bead  15 , as well as the elevated distance of the adjustable sighting bead  15  above the traditional gun butt. 
         [0026]      7   b  and  17   ab  broken lines show the distance between the top of the adjustable recoil shoulder pad  28  and the adjustable sighting bead  15 . Fastener  25   a  passes through the adjustable recoil shoulder pad  28  and the first member  24  and fastens into the traditional gun butt  7   b . This secures the adjustable recoil shoulder pad  28  and the first member  24  to the traditional gun butt  7   b , and it is the point of rotation for the adjustable recoil shoulder pad  28 . The first member  24  is located between traditional gun butt  7   b  and the adjustable recoil shoulder pad  28 .  25   b  is a fastener that travels through the first member  24  and fastens to traditional gun butt  7   b , securing the first member  24  to the traditional gun butt  7   b . This allows the user to shoulder the firearm and align the eye with the sighting bead without twisting or tilting head. 
         [0027]    Displayed in  FIG. 6 : the after market pivotal recoil shoulder pad  28  has been pivoted to the right, is substantially vertical and is in firing position. The firing mechanism  18  and the top of the gun barrel  13  have been pivoted and positioned to the right of the recoil shoulder pad  28 . Fastener  25   a  has passed through the adjustable recoil shoulder pad  28 , the first member  24  and is fastened to traditional gun butt  7   b . This connects the recoil shoulder pad  28  and the first member  24  to the traditional gun butt  7   b . Fastener  25   b  has traveled through the first member  24 , is fastened to the traditional gun butt  7   b  and connects the first member  24  to the traditional gun butt  7   b .  26  is an elongated opening in the first member  24 , and fastener  27  passes through the elongated opening  26  and fastens to the adjustable recoil shoulder pad  28 . When fastener  27  and fastener  25   a  are loosened, fastener  27  can be positioned at different places within the elongated opening  26  and tightened in desired position. Fastener  27  and fastener  25   a  can be tightened to secure the adjustable recoil shoulder pad  28  in different positions, thus allowing rotation adjustment of the adjustable recoil shoulder pad  28 . This permits the user to shoulder the firearm and align the head with the sighting bead without twisting or tilting head. 
         [0028]    Title? On a traditional shouldered firearm, the stock butt, firing mechanism, barrel and sighting mechanism are all aligned. This requires the movement of tilting and rotating the head to align the eye with the sighting mechanism in the gun mount. This additional movement and unnatural stance decrease accuracy in shooting. 
         [0029]    The primary purpose of this invention is to allow the shooter of a shouldered firearm to align the eye with the sighting bead of a shouldered firearm without tilting or rotating the head. The stock of the gun pivots about an axis and is fastened in place, making room for the shooter&#39;s head where the stock of a traditional shouldered firearm would be, thereby allowing the shooter to maintain a head position substantially perpendicular to the target, and shoot more accurately. The sighting bead is also adjusted in accordance with the stock adjustment. This natural shooting position and the reduced requirement of head movement allow for greater accuracy. For even greater shooting accuracy, the invention contains shoulder pads, which adjust upward and downward to further customize the shouldered firearm to the shooter. The shooter can adjust the shoulder pad to align the eye with the sighting bead without having to lower the head. The stock also includes spacers between the gun butt and the stock, which allow for adjustment to the length of the stock. 
         [0030]    The invention may also be created with the stock rotated about an axis and then fixed in place. This model also includes shoulder pads, which adjust upward and downward, and spacers to adjust the stock length. 
         [0031]    The invention may also be an accessory to an existing shoulder firearm. This model includes a pivoting shoulder pad-extension for the stock as well as a rotating sighting bead attachment.
