CROSS REFERENCES TO RELATED APPLICATIONS [0001] The present application is a non-provisional perfection of prior filed provisional application No. 60/595,872, filed Aug. 12, 2005. FIELD OF THE INVENTION [0002] The present invention relates to the field of rear sights for firearms and more particularly relates to a rear sight that is usable in both distance shooting and Close Quarters Combat ("CQB") scenarios (generally 7-25 yards from the target). BACKGROUND OF THE INVENTION [0003] Since artillery was created, some means of aiming the fired projectile has been necessary. One standard aiming means for modern artillery and modern personal firearms is comprised of a rear sight and a front bead. On a personal firearm such as a rifle or shotgun, the bead is located on top of the barrel near the muzzle of the weapon while the rear sight is located a significant distance behind the front bead, usually on the receiver of the weapon, toward the stock. In principle, when the front bead is viewable in the rear sight, then the weapon is properly aligned. When the front bead is simultaneously covering the target, the weapon is properly aimed. [0004] Rear sights basically have two components. The first is a sight body and the second is a sighting aperture within the body. At times, the aperture may be replaced with a sighting notch along the body's upper edge. However, such arrangements are usually exclusive of each other. In one instance where a sight aperture and a sight notch are combined, the notch is used for long range estimation, not close quarters combat, and is therefore a smaller notch to account for greater distance and inaccuracy. In other times, a small aiming aperture may be combined with a notch, affording an easily seen glimmer of light when the weapon is properly aimed. SUMMARY OF THE INVENTION [0005] The present invention departs from prior rear sights in that there is a combination of a sighting notch with a sighting aperture and the sighting notch is specifically adapted for CQB scenarios while the aperture is designed for conventional distance shooting. As such, the width of the sighting notch is at least as large, and usually larger, than the diameter of the aperture. The change in elevation angle of the weapon, the notch being above the aperture, then also accounts for the difference between CQB and distance shooting. [0006] The more important features of the invention have thus been outlined in order that the more detailed description that follows may be better understood and in order that the present contribution to the art may better be appreciated. Additional features of the invention will be described hereinafter and will form the subject matter of the claims that follow. [0007] Many objects of this invention will appear from the following description and appended claims, reference being made to the accompanying drawings forming a part of this specification wherein like reference characters designate corresponding parts in the several views. [0008] Before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not limited in its application to the details of construction and the arrangements of the components set forth in the following description or illustrated in the drawings. The invention is capable of other embodiments and of being practiced and carried out in various ways. Also it is to be understood that the phraseology and terminology employed herein are for the purpose of description and should not be regarded as limiting. [0009] As such, those skilled in the art will appreciate that the conception, upon which this disclosure is based, may readily be utilized as a basis for the designing of other structures, methods and systems for carrying out the several purposes of the present invention. It is important, therefore, that the claims be regarded as including such equivalent constructions insofar as they do not depart from the spirit and scope of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS [0010] FIG. 1 is a front schematic of the rear sight according to the present invention. [0011] FIG. 2 is the rear sight of FIG. 1 in conjunction with a schematic of a front sighting bead, aimed for distance shooting. [0012] FIG. 3 is the rear sight of FIG. 1 in conjunction with a schematic of a front sighting bead, aimed for CQB shooting. [0013] FIG. 4 is an alternate embodiment of the rear sight of the present invention utilizing a large round CQB aperture. [0014] FIG. 5 is an alternate embodiment of the rear sight of the present invention utilizing a trapezoidal notch. [0015] FIG. 6 is an alternate embodiment of the rear sight of the present invention utilizing square notch on a round sight body. [0016] FIG. 7 is an alternate embodiment of the rear sight of the present invention utilizing a round notch on a round sight body. DETAILED DESCRIPTION OF THE PRESENT INVENTION [0017] With reference now to the drawing, the preferred embodiment of the manifold is herein described. It should be noted that the articles "a", "an" and "the", as used in this specification, include plural referents unless the content clearly dictates otherwise. [0018] Referring to FIG. 1, the rear sight 2 according to the present invention comprises a main body 4 with two projections 6, 8 forming a notch 7 there between. A sighting aperture 5 is located beneath the notch. Both notch 7 and aperture 5 are generally centered about a vertical axis of the sight body. As shown in FIG. 2, projections 6, 8 may have an illumination source 3, inserted therein. The preferred source is a tritium insert, though similar constructions and concepts may be utilized. In use, the rear sight 2 is aligned with the front bead 9. As shown in FIG. 2, the bead 9 is aligned with aperture 5 for standard distance shooting. FIG. 3 depicts use in CQB scenarios, where bead 9 is aligned in notch 7. Continue reading about Rear cqb sight and system...
