In addition, numerous specific details are set forth in order to provide a thorough understanding of the embodiments described herein. However, it will be understood by those of ordinary skill in the art that the embodiments described herein can be practiced without these specific details. In other instances, methods, procedures and components have not been described in detail so as not to obscure the related relevant feature being described. Also, the description is not to be considered as limiting the scope of the embodiments described herein. The drawings are not necessarily to scale and the proportions of certain parts have been exaggerated to better illustrate details and features of the present disclosure.
- Several definitions that apply throughout this disclosure will now be presented. The term “substantially” is defined to be essentially conforming to the particular dimension, shape or other word that substantially modifies, such that the component need not be exact. For example, substantially cylindrical means that the object resembles a cylinder, but can have one or more deviations from a true cylinder. The term “about” signifies that the amount includes the specified amount, but can also include those values that are substantially close to the specified amount. Additionally by using both specified and about, the description can include just the values indicated in at least one example.
- The present technology includes an optical scope mounting system for a rocket propelled grenade (RPG) launcher. In at least one embodiment, the system can include a rail mount. The rail mount can have a lower surface shaped to be complementary to an exterior surface of the barrel of the RPG launcher and to be mounted over and in-line with a bore of the RPG barrel. Additionally, the rail mount can have an upper surface to accept a pair of rings configured to receive an optical scope. The system can further include a pair of rings; each ring of the pair of rings can have a base configured to engage with the rail mount. Additionally, each ring can have a portion configured to receive the optical scope. The rail mount can be shaped so as to be back-sloped in a direction opposite to a muzzle of the bore.
- In another embodiment of the present disclosure, a base mount is provided to be back-sloped away from the muzzle of the RPG launcher. The top of the base mount can be provided with a Picatinny style rail to facilitate mounting of the rings.
- The rings are provided with a clamping portion, which is operated by a thumb nut, to securely fasten the rings to the base. The base can be dovetailed and complementary shaped clamping portions of the lower portions of the rings securely hold the rings to the bases.
- In a further embodiment, a connecting portion of each of the rings between the base and the portion of the ring to receive the optical scope is shaped to position the optical scope offset from, and laterally of, the bore of the RPG. The positioning of the scope is important because placing the optical scope directly above the bore of the muzzle presents an awkward position for a shooter to sight through the optical sight. Accordingly, the connecting portion of the rings are configured to move the scope to the left and away from the bore of the RPG launcher to place the optical scope in position for a right eye shooter, while simultaneously elevating the scope well above the muzzle of the RPG launcher. The rings could be reversed to position the scope to the right of the muzzle for a left eye shooter. The prior art sights designed by the Russians and Chinese would not accommodate movement of the scope to allow for a different dominant eye of the shooter because the mount was to a fixed protrusion on the RPG launcher.
- These and other embodiments and objects will be better understood with referenced to the appended drawings and the detailed discussion of the illustrated embodiments.

FIG. 1 illustrates a prior artoptical sight 10 based on a Chinese design for an RPG launcher. Theoptical sight 10 is of the prism design where light entering through theobjective lens 12 passes through a prism (not shown) in the vicinity ofelement 14 which it is diverted and passes througheyepiece 16. An integral mount 18 at the base ofoptical sight 10 clamps onto a protrusion of the RPG launcher by movement of a wedge shaped portion 19 by means of alever 20. This type of mount 18 does not securely fasten theoptical sight 10 to the RPG launcher, for example, theoptical sight 10 can be dislodged by bumpinglever 20. Additionally, the nature of the clamping, by reason of a wedge shaped portion 19, does not precisely re-position thescope 10 in relation to the RPG launcher. -
FIG. 2 illustrates an optical scope according to the present disclosure. Theoptical scope 20 has anobjective lens 22 through which light enters thescope 20. After the light passes through a series of lenses and a reticle (neither shown), the light exits througheyepiece 24.Turrets Lens 22 may be provided with one or more coatings to improve brightness or filter certain wavelengths of light, as desired. Furthermore, thescope 20 can be configured to receive optical covers (not shown) that prevent dust and other debris from impacting theobjective lens 22 and/or the eyepiece 21. - The path of flight of an RPG is unlike the path of flight of a projectile filed from a rifle. RPGs do not have a symmetrical path of flight, such as a projectile fired from a rifle. In a rifle, the path of flight is symmetric, so that the flight path rises from the bore of the barrel to its greatest highest point and then descends. An RPG, on the other hand, has a first path of flight from the muzzle of the RPG launcher due to propellant in the RPG that forces it from the muzzle and a second path of flight beginning when the rockets of the RPG ignite some distance away from the muzzle. In one example, the RPG drops about 40 inches from the muzzle in the first 10-15 meters from the muzzle until the rocket ignites. In another example, the RPG drops about one meter from the muzzle in the first ten to fifteen meters from the muzzle until the rocket ignites. In other embodiments, different drops from the muzzle are also considered. The above example is considered to be a non-limiting example. In the case of a projectile from a rifle elevation from the muzzle is constant until the apogee of the projectile path is reached. Thus, the fixed aiming point 46 permits the RPG to hit a target at known distance, for example, fifty meters, even though the path of flight is asymmetric and is somewhat also dependent on ambient temperature, which ambient temperature can vary greatly (either hot or cold) from room temperature. While the example of fifty meters is mentioned herein, other examples can include any predetermined distance, for example fifty yards, one hundred meters, or one hundred yards.
- Therefore, the optical scope mounting system of the present disclosure utilizes a unique mounting system in which the base mount is back-sloped. “Back-sloped” as used herein indicates that the base mount is off a uniformly increasing slope resulting in the rear of the base mount being of higher elevation than the front of the base mount (“rear” being that portion of the base mount opposite the muzzle of the RPG launcher and the “front” being that portion of the base mount that that is proximate to the muzzle of the RPG launcher).

FIG. 3 is a perspective view of abase mount 30. Thebase mount 30 has a first end 31and anopposite end 32 where theopposite end 32 is back-sloped or rises in elevation at a uniform rate fromfirst end 31 toopposite end 32. As illustrated thebase mount 30 can be in the style of a Picatinny Rail. In other embodiments, different types of rails can be implemented. When the mount is of the Picatinny Rail type, the mount provides for mounting of a variety of different available attachments while also providing a base for the optical scope as described herein. -
FIG. 4 is an elevation view of thebase mount 30 ofFIG. 3 . (Throughout the specification and drawing, like elements in different views may be given the same numeral identifiers). InFIG. 4 , the details of theupper surface 33 ofbase mount 30 illustrate the Picatinny Rail configuration of alternatingprotrusions 34 and valleys 35 being formed between twoadjacent protrusions 34. Theprotrusions 34 can be configured to have a flat upper surface. In other embodiments, the upper surface can have another shape such as a curve or two sloping sides.Base mount 30 has a dove-tail configuration shown as dove-tail portions upper surface 33 to co-operate with the base of the rings 50 as described below. - The base mount may have a series of
apertures base member 30 to the RPG launcher.Apertures lower end 42 ofbase mount 30 is configured to be complementary to the outer periphery of an RPG launcher and so may be radiused or beveled to fit snugly against a typically curved outer surface of an RPG launcher. -
FIG. 5 is a schematic end view of thebase mount 30 ofFIG. 3 .FIG. 5 further illustrates thebase mount 30 to allow for depiction of thedovetail portions lower end 42 ofbase mount 30. In at least one embodiment, thedovetail portions rings 60 can be mounted as shown inFIG. 10 , which is described below. The attachment of therings 60 is described in relation to a clamping configuration for the illustratedbase mount 30. When thebase mount 30 takes different shapes corresponding changes in the clamping can be made. -
FIG. 6 is a schematic view of aring 60, which mounts tobase member 30 by adjustably clampinglower clamping members dovetail portions thumb nut 63 can be used to apply sufficient force upon treaded stud 64 (only partially shown inFIG. 6 ) to urge clampingmembers tail portions ring 60 ontobase mount 30. The exposed portion of threadedstud 64 will fit into the valley 35 between adjacent hills 35, 35 in the Picatinny rail. -
Ring 60 has abody portion 65 which will offset theoptical scope 20 laterally of thebore 80 of theRPG launcher 81 and above the centerline of thebore 80 ofRPG launcher 81, even if thebase mount 30 were uniform in height. Laterally as used herein refers to spacing theoptical scope 20 off to one side of thebore 80 so that it is not over the top portion of thebore 80. For example, theoptical scope 20 can be offset laterally to the left side of the centerline of thebore 80. In other embodiments, theoptical scope 20 can be offset laterally to the right side of the centerline of thebore 80. The present disclosure can allow for switching the scope from the left side to the right side and vice versa using the same pair ofrings 60. The rings just need to be rotated about one hundred-eighty degrees. - However, given that the
base mount 30 is back sloped, the line of sight throughoptical scope 30 will not be parallel to thecenterline 80 to the bore ofRPG launcher 81, but will be at an angle α thereto. In one embodiment, the angle α is in the range of about 2°-3°. In one specific embodiment, the angle α is about 2.50°. The angle α is calculated based on the behavior of the RPG round that the RPG launcher is configured to fire. For example, when the angle α is 2.5° as described herein, the angle can be based on the above described characteristics of the RPG. The divergence between thecenterline 80 of the bore orRPG launcher 81 and the line of sight throughoptical scope 30 is illustrated inFIG. 9 . -
