Description:
FIELD OF THE INVENTION 
       [0001]    The application relates to a method and apparatus for replacing the original rear sight of an SKS, AK, PKM, or other related tangent sight system with another sighting system. 
       BACKGROUND OF THE INVENTION 
       [0002]    1. Prior Art 
         [0003]    Presently, AK type rifles have been extremely popular amongst recreational shooters, hunters, militaries, security personnel, and other shooters. The popularity of such rifles is largely due to their durability, low production cost, and ease of use. However, when these rifles were originally designed, mounted sights were rarely, if ever, used. As the use of mounted optics has become more popular, different methods for mounting said optics on SKS, AK, PKM, and other related tangent sight system weapons have been employed. One popular method involves installing a side rail mount on the weapon such that the sight is attached at the side of the rifle and contorted to aid sight at the top portion of the rifle. Adversely, installing a side rail mount in this way is complicated and makes disassembling the weapon much more difficult after installation. Also, attaching the sight at this point exposes the sight to much of the kick from the weapon&#39;s firing; as such accuracy is marginal at best. Another popular method is to mount sights on the front end gas tube directly or indirectly on the same. Adversely, mounting sights in this way places the sight so far away from the shooter&#39;s eye as to make the sight difficult to operate effectively. 
         [0004]    U.S. patent application Ser. No. 10/790,408 provides a method and apparatus for mounting rifle scopes by replacing the original rear sight of the weapon with a sight base to which various scopes may be mounted. According to this invention, the sight base and corresponding mounted scopes are unable to maintain or adjust position relative to the lateral ends of the rifle because the left/right position is maintained by the friction between certain rolling pins and corresponding holes, and is therefore unpredictable and hard for the user to control. Additionally, the position of the screws on the top of said sight base corresponds to depressions in the rear battle sight mount which forms the base of the original rear sight. This correspondence is not ideal because it requires the use of longer, less accurate screws to maintain height, one of the most important elements of sighting a weapon. 
         [0005]    There exists a need for a method and apparatus for mounting sights onto SKS, AK, PKM, and other related tangent sight system rifles such that said method and apparatus provides for effective mounting of said sights without permanently altering the rifle that allows for a flexible, adjustable mount of the sight. 
         [0006]    2. Objects and Advantages 
         [0007]    Accordingly, several objects and advantages of this invention are: 
         [0000]    (a) to provide for the stable and effective attachment of weapon sights to the rifle;
 
(b) to provide for the possible addition of a rail system or other mounting base that allows for attachment of various accessories;
 
(c) to provide for stable and effective attachment of various accessories;
 
(d) to provide for flexible adjustment of the weapon sights;
 
(e) to provide sights at a height that allows the weapon to be used as naturally as if the shooter were looking through the original iron sight;
 
         [0008]    Further objects and advantages of this invention will become apparent from a consideration of the drawings and ensuing description.

       OPERATION  
     FIG.  3   
       [0023]    As shown in  FIG. 3 , according to the present invention, in the preferred embodiment, rear battle sight mount  10  attaches the rifle (not shown), by at attachment of rear battle sight mount to rifle  11  such that rear battle sight mount  10  is stable on the rifle (not shown). Side screw  40  and nut  41  engage rear battle sight mount  10  and accessory mount base  20 . Through varying the engagement of side screw  40  and nut  41  relative to rear battle sight mount  10  and accessory mount base  20 , side screw  40  provides for adjustment of the leftright position of the accessory mount base  20  relative to rear battle sight mount  10 . According to certain embodiments, front screws  31  engage integration holes for front screws  23 , whereby front screws  31  push against rear battle sight mount  10 , such that the angle of the line of sight relative to a line parallel to the barrel of the rifle can be adjusted. Additionally, engaging front screws  31  with integration holes for front screws  23  allows for increased stability of the positioning of the accessory mount base  20  during regular use of the rifle. According to certain embodiments, back screw  32  engages accessory mount base  20  and back screw  32  pushes against the top of rear battle sight mount  10  so as to increase the stability of accessory mount base  20  during regular use of the weapon. 
         [0024]    According to certain embodiments, accessory mounts such as optical sights and laser sights (not shown) are attached to the top of accessory mount base  20 .
