Definitions

  • the invention relates generally to a mounting assembly for use on a long gun. More particularly, the invention relates to a mounting assembly for mounting a reticle type sight on a long gun to give minimal eye relief while enabling co-witnessing.
  • Red dot sights use refractive or reflective optics to generate an image of a reticle, typically a red dot, that appears to be projected onto a target.
  • Red dot sights typically have no magnification. As such, they have unlimited eye relief. Thus, the image will be clear when viewed within a few inches, to a few feet, behind the sight.
  • a field of view through a sight or scope is dependent on eye relief. Therefore, the farther back a shooter's eye is from the Red dot sight, the smaller the field of view. Conversely, the closer the shooter's eye to the Red dot sight, the larger the field of view.
  • a Red dot sight is usually mounted on receiver or barrel of a long gun. Mounting the sight on the receiver typically gives a shooter between seven and sixteen inches of eye relief. When mounted on the receiver, the Red dot sight is usually mounted either above and/or behind the gun's iron sights. Because the eye relief is usually between seven and sixteen inches, the shooter's field of view is significantly smaller than it would be if the sight were mounted closer to the shooter and providing less, but adequate, eye relief. In addition, because the sight is typically mounted either above and/or behind the gun's iron sights, the sight line of the shooter is higher than if the shooter were to use the traditional iron sights. The higher sightline may prohibit the shooter from co-witnessing and/or using the Red dot sight.
  • Embodiments of the present invention provide for a mounting assembly for mounting a reticle or optical type sight on a long gun.
  • the mounting assembly includes a mounting plate for securing the mounting assembly on a rearward portion of a long gun.
  • the mounting assembly includes a mounting block that may be coupled to a top portion of the mounting plate.
  • the mounting assembly contains a mounting plate having at least one bore to couple the mounting plate to a rearward portion of the long gun.
  • a mounting block is coupled to a top portion of the mounting plate and is configured to secure a reticle type sight.
  • Yet another aspect of the present invention provides for a method of mounting a reticle type sight on a long gun for effectively increasing a field of view through the reticle type sight.
  • the method includes securing a mounting assembly between a removable or detachable stock and a receiver of the long gun.
  • the mounting assembly consists of a mounting block coupled to a top portion of the mounting plate.
  • a reticle type sight may be coupled to a top portion of the mounting plate to give a shooter less than five inches of eye relief while the head of the shooter remains appropriately positioned on the comb.
  • FIG. 1 is an isometric view of a mounting assembly according to an embodiment of the invention.
  • FIG. 2 is an isometric view illustrating the mounting assembly of FIG. 1 with a reticle type sight coupled to a mounting block of the mounting assembly according to an embodiment of the invention.
  • FIG. 3 is an exploded view of the mounting assembly and reticle type sight illustrated in FIG. 2 , combined with an optional spacer according to an embodiment of the invention.
  • FIG. 4 is an illustration of the mounting assembly and the reticle type sight of FIG. 2 positioned on a long gun to give a shooter less than five inches of eye relief according to an embodiment of the invention.
  • FIG. 5 is an elevated rear view of the mounting assembly and reticle type sight positioned on the long gun as shown in FIG. 4 to enable co-witnessing according to an embodiment of the invention.
  • the term “rearward” describes a location on a long gun that is behind the trigger of the gun, such as for example, a location on a stock or butt of the gun, or between a detachable stock and receiver.
  • comb describes the top of a gun's stock, where a shooter places or rests his cheek when mounting a gun.
  • placing a shooter's head on an appropriate place or position on the comb describes the shooter's head or cheek resting on the comb without “climbing the comb” or moving the head forward along the stock to decrease eye relief.
  • FIG. 1 illustrates a mounting assembly 100 according to an embodiment of the invention.
  • Mounting assembly 100 consists of a mounting plate 110 and a mounting block 120 .

  • connection elements 125 are shown and described, there are various ways in which a reticle type sight may be secured to the mounting block as described herein.
  • the sight may be coupled and secured to the mounting block 110 using clasps, screws, and other types of fasteners.
  • Other embodiments may provide that the sight may be welded, or similarly secured, to the mounting block.
  • Mounting plate 110 preferably contains one or more bores 115 ( FIG. 1 ) to enable the mounting plate 110 to be secured between a removable stock and a receiver of a long gun.
  • each of the bores 115 or sockets may be of varying diameters to enable the mounting assembly 100 to be used secured to a variety of different long guns with detachable/removable stocks.
  • the mounting plate 110 may be inserted to align with a socket of a receiver of a long gun (not shown) and secured between the stock and receiver when the stock is mounted to the receiver.
  • bores 115 may align with one or more pins, and/or the receiver socket, used to mate the receiver and stock together.
  • the width of the mounting plate 110 may be wide enough to provide a sturdy base for the mounting assembly 100 , yet small enough to not noticeably increase stock or gun length.
  • the mounting plate 110 also allows the mounting assembly 100 to be coupled to many different types of guns without modifying any gun parts.
  • FIG. 2 shows the mounting assembly 100 of FIG. 1 with a reticle type sight 130 coupled to a top planar portion of the mounting block 120 .
  • the reticle type sight may be an electronic type sight, an optical type sight, a holographic type sight, a fiber optic type sight, or a Red dot type sight.
  • Each of the sights may be closed or open frame. It is also contemplated that the use of LED's and either transmissive or reflective type OLED's may be used with the sights to illuminate the reticle.
  • the reticle type sight 130 may fitted with recesses or sockets (not shown) on a bottom planar portion of the sight 130 to enable the reticle type sight to mate with the connection elements 125 of the mounting block 120 .
  • other fasteners such as screws, clips or clamps may also be used to secure the sight 130 to the mounting block 120 .
  • Other embodiments provide that a rear portion of a traditional or telescopic type scope may be secured to the mounting block to give the scope additional security.
  • FIG. 3 is an exploded view of the mounting assembly 100 according to an embodiment of the invention.
  • mounting assembly 100 includes a mounting block 120 that may be coupled to a mounting plate 110 .
  • mounting plate 110 may contain a second set of bores 117 to secure the mounting block 120 to the mounting plate 110 .
  • the second set of bores 117 align with the bores 127 of the mounting block 120 .
  • Such an alignment permits insertion of screws, or other types of fasteners, to secure the mounting block 120 to mounting plate 110 .
  • the mounting block 120 may be easily coupled and removed from the mounting plate 110 either before or after the mounting plate has been coupled to the long gun.
  • the mounting plate 110 may be secured between the stock and receiver of the long gun before the mounting block 120 is attached. Once the mounting plate 110 has been secured, the mounting block 120 can be coupled to the mounting plate 110 .
  • Such an implementation not only provides for ease of assembly, but also enables one mounting block, configured to fit a first type of a reticle type scope, to be switched for a second mounting block, configured to fit a second type of reticle type scope, without disassembling the entire long gun. Accordingly, the mounting plate 110 may be configured to universally fit mounting blocks 120 of different sizes and shapes.
  • Mounting assembly 100 may also include a removable spacer 140 to affect a higher sightline for a shooter.
  • Multiple spacers 140 may be used and stacked on top of one another to enable a shooter to achieve a desired sightline.
  • the spacer 140 may have a fixed height or the height of the spacer 140 may be adjustable.
  • the reticle type sight 130 may be equipped with an elevation screw that may be used separately, or in conjunction with, the spacer 140 .
