SYSTEMS AND DEVICES FOR DETERMING ACCURACY IN MARKSMANSHIP
Measuring devices and systems for determining accuracy in marksmanship of one or more shots after firing a firearm at a point of aim are described. Each of the measuring devices includes a transparent sheet configured to be overlaid on the point of aim and the one or more shots, the transparent sheet having printed thereon: a plurality of vertical lines, a plurality of horizontal lines, the plurality of vertical lines and the plurality of horizontal lines forming a grid pattern, and a point of aim alignment marking, the point of aim alignment marking being located at a center of the grid pattern.
The present disclosure relates generally to systems and devices for determining accuracy in marksmanship after firing of a firearm. In particular, systems and devices for determining a minute of arc of shots relative to a point of aim are described.
Determining accuracy of marksmanship during target practice is important for improvement of marksmanship (e.g., precision, accuracy, etc.). Normally, shots are fired onto a paper target and the shots are compared to a location of a point of aim. A measurement of accuracy can be determined (e.g., a minute of arc/ minute of angle [MOA], etc.), and the measurement can then be used to adjust the sight for a firearm and improve, accuracy of subsequent shots.
Known target practice systems and devices are not entirely satisfactory for the range of applications in which they are employed. For example, existing target practice systems use disposable paper targets that are expensive and are single-use. In addition, conventional target practice systems are not easily transportable and mountable for use in the field.
Thus, there exists a need for target practice systems and devices that improve upon and advance the design of known target practice systems. Examples of new and useful target practice systems and devices relevant to the needs existing in the field are discussed below.
Disclosure addressing one or more of the identified existing needs is provided in the detailed description below. Examples of references relevant to target practice systems and devices include U.S. Patent References: U.S. Pat. No. 4,244,586, U.S. Pat. No. 6,213,470, U.S. Pat. No. 6,845,567, U.S. Pat.

SUMMARYThe present disclosure is directed to measuring devices and systems for determining accuracy in marksmanship of one or more shots after tiring a firearm at a point of aim. Each of the measuring devices including a transparent sheet, the transparent sheet configured to be overlaid on the point of aim and the one or more shots, the transparent sheet having printed thereon: a plurality of vertical lines, a plurality of horizontal lines, the plurality of vertical lines and the plurality of horizontal lines forming a grid pattern, and a point of aim alignment marking, the point of aim alignment marking being located at a center of the grid pattern. In some examples, the point of aim alignment marking is configured to be aligned with the point of aim and the grid pattern is configured to measure a vertical distance and a horizontal distance of the one or more shots relative to the point of aim alignment marking and the point of aim. In some further examples, one or more of the vertical distance and the horizontal distance of the one or more shots are used to determine a minute of arc for adjusting a sight of the firearm.

With reference to
Measuring devices 100 and 200 address many of the shortcomings existing with conventional systems and devices for determining accuracy in marksmanship. For example, conventional systems and devices are single-use, while the presently described devices are reusable. In another example, conventional systems and devices are not easily transportable for use in the field (i.e., outside of a normal target practice or shooting range) because they use disposable paper targets that require a flat surface and/or an attachment mechanism for mounting. The presently described systems and devices address this problem because the devices are easily transportable and targets do not require a specific mounting mechanism and/or surface.
Thus, the presently described systems and devices for determining marksmanship solve the issue of zeroing and/or sighting of a weapon system without the requirement of paper targets, thereby reducing an overall cost of the determining marksmanship during target practice and allowing determination of marksmanship to be easily carried out in the field.
As shown in
Plurality of vertical lines 104 and plurality of horizontal lines 106 intersect to form a plurality of uniformly sized blocks 116 arranged in a grid pattern 118. In one specific example, each of the uniformly sized blocks is a ¼″ ×¼″ block. It will be appreciated that in other examples each of the uniformly sized blocks may be larger or smaller in size.
As depicted in
In the present example, point of aim alignment marking 108 is an open circular shape (i.e., a circular shape that is not filled in). More specifically, point of aim alignment marking 108 includes an inner circle 126 and an outer circle 128. Inner circle 126 is comprised of a bolded line (i.e., a line having a greater width), while outer circle 128 is comprised of a non-bolded line (i.e., a line having a thinner width).
In one specific example, point of aim alignment marking 108 has a diameter of 4 cm and spans an area of approximately four of blocks 116. In other examples, the circular shape may be larger or smaller, the circular shape may be comprised of a greater or fewer number of circles (i.e., one circle, three or more concentric circles, etc.), and/or the circular shape may be filled-in.
Also shown in
In the present example, sight adjustment key 110 includes a 4X OPTICS key 130, a REFLUX SITE key 132, an M4 CARBINE RIFLE key 134, and an M16 FULL LENGTH RIFLE key 136. Further, M4 CARBINE RIFLE key 134 and M16 FULL LENGTH RIFLE key each include an IRON SITE WINDAGE KEY (134a and 136a, respectively) and an IRON SITE ELEVATION KEY (134b and 136b, respectively). Each of the above described keys includes a number of adjustments 138 (i.e., clicks) and a corresponding distance 140 (i.e., number of blocks). It will be appreciated that the IRON SITE WINDAGE KEY is provided as a key for determining an MOA of the sight windage and that the IRON SITE ELEVATION KEY is provided as a key for determining an MOA of sight elevation.
In alternate examples, the sight adjustment key may be located in a different region of the transparent sheet (e.g., a top right-hand corner, a top left-hand corner, a bottom right-hand corner, etc.). In other alternate examples, the sight adjustment key may be separate from the transparent sheet. For example, the sight adjustment key may be printed on a separate paper and laminated or the sight adjustment key may be printed on a sleeve/case for the transparent sheet. Further, it will be appreciated that for any of the above examples the sight adjustment key can include more or fewer keys for more of fewer types of optics and/or firearms.
The sight adjustment key is a location on the measurement device that the user (i.e., the marksman) can reference after a target practice session in order to identify the correction which need to be made in subsequent target practice sessions. It will be appreciated that the adjustment key can include a variety of sights and scopes for selected firearms, based on the user's preferences (i.e., manufactured to suit a user's preference). It will be further appreciated that an alternative measurement to MOA blocking can be used. For example, some alternative measurement devices can be made for specific firearms and sights which will have specific block sizes to account for the ballistics of the sight, the firearm type, and/or the ammunition type.

The cutouts can be placed directly over the shot group after firing (i.e., one or more shots) in order to identify the distance of the shots from each other. When firing at designated distances the shooter will be able to ensure that the shot group's size is within a specific diameter. In alternate examples, the transparent sheet can include more of fewer cutouts of greater or smaller sizes and/or the cutouts can be in a different location on the transparent sheet (e.g., bottom left corner, top right corner, top left corner, etc.).

Further, in the present example, target 148 is mounted on a target stand 158 and marksman 144 is standing 100 yds from target stand 158. In alternate examples, marksman 144 can stand further from or closer to target stand 158. It will be appreciated that during target practice session 142, marksman 144 can fire one or more shots at target 148.
As depicted in
In one specific example, adjustment based on a single shot fired can be determined. Specifically, shot 160b is a substantially horizontal distance of 10 blocks to the right of point of aim 156 and substantially 6 blocks above point of aim 156. Sights 150 can be adjusted for windage using IRON SITE WINDAGE key 136a and the horizontal distance from the point of aim for shot 160b. Accordingly, the horizontal adjustment can be calculated as follows:
10 blocks×4 adjustments/2 blocks=20 adjustments
Further, sights 150 can be adjusted for elevation using IRON SITE ELEVATION key 136b and the vertical distance from the point of aim for shot 160b. Accordingly, the vertical adjustment can be calculated as follows:
6 blocks×3 adjustments/4 blocks=4.5 adjustments
Accordingly, for shot 160b, an overall adjustment is 20 adjustments left, 4.5 adjustments down.
In another example, a general adjustment for the shot group can be determined. Shot group 160 is a substantially horizontal distance of 12 blocks to the right of point of aim 156 and substantially 4 blocks above point of aim 156. Sights 150 can be adjusted for windage using IRON SITE WINDAGE key 136a and the horizontal distance from the point of aim for shot 160d. Accordingly, the horizontal adjustment can be calculated as follows:
12 blocks×4 adjustments/2 blocks=24 adjustments
Further, sights 150 can be adjusted for elevation using IRON SITE ELEVATION key 136b and the vertical distance from the point of aim for shot group 160. Accordingly, the vertical adjustment can be calculated as follows:
4 blocks×3 adjustments/4 blocks=3 adjustments
Accordingly, for shot group 160, an overall adjustment is 24 adjustments left, 3 adjustments down.
It will be appreciated that overall adjustment for other shots fired (i.e., 160c, 160e, 160f) can be determined using a similar method of calculation. If desired, horizontal adjustments and vertical adjustments can be averaged for all of the shots tired that are within the area of target 148 that is overlaid with measuring device 100. Alternatively, the marksman can measure accuracy to a general center of the shoot group (i.e., shots 160) as describe above. The marksman can then adjust his aim/sights (e.g., elevation and/or windage) for subsequent target practice sessions according to the average overall adjustment (i.e., the average horizontal adjustment and the average vertical adjustment) and/or for the shot group in order to improve marksmanship.
In alternate examples of a target practice session, the marksman can stand at a different distance from the target. For example, the marksman can stand 25 m from the target. Additionally or alternatively, the marksman can use (i.e. shoot with) a different type of firearm (e.g., an M4 carbine rifle, a handgun, AR-15], etc.). Further, in alternate examples, a target practice session can be performed outside of a normal shooting range (i.e., a shooting range not including a target and target stand), such as target practice session 242 shown in

As can be seen in
Plurality of vertical lines 204 and plurality of horizontal lines 206 intersect to form a plurality of uniformly sized blocks 216 arranged in a grid pattern 218. In one specific example, each of the uniformly sized blocks is a ¼″×¼″ block. It will be appreciated that in other examples each of the uniformly sized blocks may be larger or smaller in size.
As depicted in
In contrast to point of aim alignment marking 108, point of aim alignment marking 208 is a silhouette shape (i.e., a shape similar to an outline of a human body). More specifically, point of aim alignment marking 108 includes a silhouette 228 and a contrasting inner circle 226. In the present example, silhouette 228 is filled-in (i.e., darkened) while inner circle 226 is negative space (i.e., clear).
In one specific example, point of aim alignment marking 208/silhouette 228 generally can have a width of 4 cm and a height of 8 cm. More specifically, the head portion of the silhouette can have a width of 0.33 cm. Further, in this specific example, inner circle 226 has a diameter of 4 cm. In other examples, the silhouette and/or the inner contrasting circle may be larger or smaller. Additionally or alternatively, the silhouette can be un-filled (i.e., not colored in) and the contrasting circle can be a circular line printed on the transparent sheet.
It will be appreciated that sight adjustment key 210 is substantially identical to sight adjustment key 110. In alternate examples, the sight adjustment key may be located in a different region of the transparent sheet (e.g., a top right-hand corner, a top left-hand corner, a bottom right-hand corner, etc.). In other alternate examples, the sight adjustment key may be separate from the transparent sheet. For example, the sight adjustment key may be printed on a separate paper and laminated or the sight adjustment key may be printed on a sleeve/case for the transparent sheet. Further, it will be appreciated that for any of the above examples the sight adjustment key can include more or fewer keys for more of fewer types of firearms.
It will be appreciated that first cutout 212 and second cutout 214 are substantially identical to first cutout 112 and second cutout 114, respectively. Accordingly, first cutout 212 and second cutout 214 are located in a bottom right-hand corner of transparent sheet 202. Each of first cutout 212 and second cutout 214 are circular in shape. In one specific example, first cutout 212 has a diameter of 1 in and second cutout 214 has a diameter of 4 cm. Each of the cutouts are configured to identify if a shoot group (i.e., a plurality of shots fired) is within the 25 meter zero/sighting or 100 meter zero/sighting, respectively. In alternate examples, the transparent sheet can include more of fewer cutouts of greater or smaller sizes and/or the cutouts can be in a different location on the transparent sheet (e.g., bottom left corner, top right corner, top left corner, etc.). It will be appreciated that cutouts 212 and 214 can be used by the marksman as described above in reference to cutouts 112 and 114.
