DETAILED DESCRIPTION

Described below are embodiments of a travel limiting device (as well as individual components of the travel limiting device) that can be attached to a firearm. Methods of using and installing the travel limiting device on the firearm are also disclosed. The firearm may be a conventional firearm. For example, the firearm may be an M-16 style rifle, an AR-15 style rifle, an AR-10 style rifle, or an M-4 style rifle, among others. Any suitable firearm may be used, particularly any suitable firearm that includes an adjustable buttstock.

The travel limiting device may be positionable within a position slot and a channel in a buffer tube of a firearm to limit the adjustability of a buttstock. In some instances, the travel limiting device may include a main body having a stop surface. The main body may be positionable within the channel. In certain embodiments, the main body may be omitted.

The travel limiting device also may include a protrusion extending from the main body. The protrusion may be positionable within the position slot. In some instances, the protrusion may be configured to securely mate with the position slot. For example, a diameter of the protrusion may be larger than a diameter of the position slot. In some embodiments, the protrusion may comprise a star-shaped boss, a round boss, a square boss, a triangular boss, or the like. In one example, the protrusion may be secured within the position slot by an adhesive. In other instances, the protrusion may be expandable within the position slot to secure the protrusion within the position slot. In yet other instances, the protrusion may be secured within the position slot by a double-sided tape. In certain embodiments, a hole may pass through the protrusion and the main body.

Turning now to the drawings, FIGS. 1-4 depict a travel limiting device 100. The travel limiting device 100 may be used to limit the adjustability of a buttstock on a firearm. For example, as depicted in FIGS. 2-4, the travel limiting device 100 may be configured to limit the adjustability of a buttstock along a buffer tube 102. In some instance, the buffer tube 102 may include a channel 104 in which a portion of the buttstock may slide back-and-forth. The channel 104 may include a number of positon slots 106. A moveable protrusion on the buttstock may be configured to slide along the channel 104 and mate with one of the positions slots 106 in order to secure the buttstock in place. An example of a moveable buttstock comprising a moveable protrusion 64 that is positionable within a number of position slots in a buffer tube 34 is disclosed in U.S. Pat. No. 8,341,868, which is incorporated by reference herein in its entirety. Depending on the length of the channel 104 and the number of position slots 106, the buttstock may be positioned in a number of different configurations.

Some users, however, may wish to limit the adjustability of the buttstock to a limited number of configurations. In such instances, one or more travel limiting devices 100 may be positioned within the channel 104 and the position slots 106 in order to limit the length of the channel 104. In some instances, two travel limiting devices 100 may be disposed within the channel 104. For example, the two travel limiting devices 100 may face one another (e.g., as mirror images) to limit the length of the channel 104 to the distance between the two travel limiting devices 100. In other instances, only a single travel limiting device 100 may be positioned within the channel 104 and one of the position slots 106 in order to limit the length of the channel 104 to the distance between an end of the channel 104 and the travel limiting device 100.

The use of one or a number of the travel limiting devices 100 may limit the number of position slots 106 available for the moveable protrusion on the buttstock to mate with. For example, the moveable protrusion on the buttstock may be limited to sliding along the channel 104 between the two travel limiting devices 100 or between a single travel limiting device 100 and an end of the channel 104. In this manner, the full range of the channel and all of the position slots 106 may not be available for mating with the moveable protrusion on the buttstock.

Turning back to FIG. 1, in certain embodiments, the travel limiting device 100 may include a main body 108. In some instances, the main body 108 may be positioned within the channel 104 of the buffer tube 102. The main body 108 may be sized and shaped to be positioned within the channel 104. The main body 108 may be any suitable size, shape, or configuration. In some instances, the main body 108 may include a stop surface 110. The stop surface 110 may engage a portion of the buttstock (e.g., the moveable protrusion) to limit the movement of the buttstock within the channel 104. In some instances, the stop surface 110 may be generally perpendicular to a longitudinal axis of the channel 104. In other instances, the stop surface 110 may be angled. The stop surface 110 may be any suitable size, shape, or configuration. The stop surface 110 may prevent the moveable protrusion on the buttstock from sliding within the channel 104 once the moveable protrusion on the buttstock engages (e.g., abuts) the stop surface 110.

When two limiting devices 100 are used, the stop surfaces 110 may face each other. In this manner, as depicted in FIGS. 3 and 4, the moveable protrusion on the buttstock may be limited to sliding along the channel 104 between the stop surfaces 110 of the two travel limiting devices 100. As a result, the full range of the channel 104 and all of the position slots 106 may not be available for mating with the moveable protrusion on the buttstock. Instead, the stop surfaces 110 of the two travel limiting devices 100 may limit the movement of the moveable protrusion on the buttstock to only the position slots 106 located between the two stop surfaces 110.

In certain embodiments, referring back to FIG. 1, the travel limiting device 100 may include a protrusion 112. The protrusion 112 may extend from the main body 108. In some instances, the protrusion 112 may extend from the main body 108 in a direction generally perpendicular to a longitudinal axis of the channel 104. In other instances, the protrusion 112 may be angled. The protrusion 112 may be any suitable size, shape, or configuration. The protrusion 112 may be positioned within one of the position slots 106. In some instances, the protrusion 112 may be configured to securely mate with the position slots 106. In other instances, the protrusion 112 may be held in place by an adhesive or tape (e.g., double-sided tape). In yet other instances, the protrusion 112 may be screwed into the positon slots 106. In still other instances, the protrusion 112 may be snap-fit or pressure fitted into the positon slots 106. For example, a diameter of the protrusion 112 may be slightly larger than a diameter of the position slots 106. In example embodiments, the protrusion 112 may comprise a star-shaped boss, a round boss, a square boss, or a triangular boss. The protrusion 112 may be any shape. The main body 108 and the protrusion 112 may be made of the same or different material. The travel limiting device 100 may be plastic, rubber, metal, composite, or a combination thereof. The travel limiting device 100 may comprise any suitable material or combination thereof.

In some instances, a hole 114 may extend through the protrusion 112 and the main body 108. The hole 114 may be used to screw the protrusion 112 into the position slots 106. In other instances, the hole 114 may be used to expand the protrusion 112. For example, the protrusion 112 may be expandable within the position slots 106 to secure the protrusion 112 within the position slot 106. In one embodiment, the protrusion 112 may include an expandable slit, which expands the protrusion 112 within the positon slots 106 when a wedge is inserted into the hole 114. The wedge may be any size, shape, or configuration, such as a triangular wedge, a cone wedge, or a ball wedge.

In an alternate embodiment, the main body 108 may be omitted. In such instances, one or more of the protrusions 112 may act as a plug and not limit the movement of the buttstock within the channel 104. That is, one or more of the protrusions 112, with the main body 108 omitted, may be positioned within one or more of the position slots 106 to prevent the moveable protrusion on the buttstock from mating with the respective position slots 106 such that the buttstock slides along the channel 104 and passes the respective position slots 106. In some instances, the protrusions 112 may be disposed within the position slots 106, with a surface of the protrusions 112 being flush with the channel 104 to enable the moveable protrusion on the buttstock to slide along the channel 104 and pass the respective position slots 106. Any number of protrusions 112 may be used to plug one or more of the position slots 106. In this manner, the systems and methods disclosed herein may enable a user to limit the distance in which the buttstock can travel within the channel 104, as well as limit which of the position slots 106 the moveable protrusion on the buttstock can mate with. As a result, the user may customize the adjustability of the buttstock in order to quickly and reliably position the buttstock in a number of desired locations.
