Thus, the detailed description herein is presented for purposes of illustration only and not of limitation. For example, the steps recited in any of the method or process descriptions may be executed in any order and are not necessarily limited to the order presented. Furthermore, any reference to singular includes plural embodiments, and any reference to more than one component or step may include a singular embodiment or step. Also, any reference to attached, fixed, connected or the like may include permanent, removable, temporary, partial, full and/or any other possible attachment option. Additionally, any reference to without contact (or similar phrases) may also include reduced contact or minimal contact.

Different cross-hatching and/or surface shading may be used throughout the figures to denote different parts but not necessarily to denote the same or different materials.

The features and elements disclosed herein may be combined in various combinations without exclusivity, unless expressly indicated herein otherwise. These features and elements as well as the operation of the disclosed embodiments will become more apparent in light of the following description and accompanying drawings.

The various systems described herein are described in the context of and operation of an AR-15/M-16 style rifle. However, the system may be used on any suitable firearm and/or other device where the various systems may improve the function, reliability and/or manufacturability of the system. Moreover, the various systems described herein may be used independently or in conjunction with one another. In this regard, various portions of the systems described herein may be used with various other portions of the systems described herein.

In various embodiments and with reference to FIG. 1, a firearm 100 and more specifically AR-15 style rifles may comprise a lower receiver 110 and an upper receiver 115. Firearm 100 may also comprise a barrel 117. Lower receiver 110 and upper receiver 115 may be detachably coupled to one another using a coupling mechanism (e.g., a pin and catch system).

As used herein, terms such as axial, lateral, vertical, forward, rearward, upper, and lower, among others, are used to provide a relative frame of reference for explanatory purposes and are not intended to limit the disclosure. For example, the term axial generally denotes a direction substantially parallel to a longitudinal length of firearm 100, while the term lateral generally denotes a direction substantially perpendicular to a plane that bisects firearm 100. The term vertical generally denotes a direction that is substantially perpendicular to the axial and lateral directions. The vertical direction is substantially perpendicular to the ground when the firearm 100 held with the barrel 130 substantially parallel to the ground, but not otherwise.

In various embodiments, typical AR-15/M-16 style rifles may generally comprise a right-handed magazine release. This magazine release allows an operator to depress a magazine release button and remove a detachable magazine from the lower receiver of the rifle. In response to being activated, the button forces the lever away from the magazine (e.g., radially away from the centerline of the rifle) allowing the magazine to drop free and/or be removed from the magazine well. Moreover, where a typical system is employed, the button is installed on the right side of the rifle and, as such, must be activated on the right side of the rifle. Stated another way, this configuration allows a magazine to be released from one side of the rifle. This configuration may cause a user to have to reach over or around from the left side to the right side of the rifle to release the magazine.

In various embodiments and with reference to FIGS. 2A-2F, magazine release system 220 may comprise a magazine release button 222, a magazine catch spring 224, a magazine catch 226, an ambidextrous magazine release button 228, and a pivot screw 229. Magazine release system 220 may be installed on lower receiver 210 of firearm 200.

In various embodiments, magazine release button 222 may house and be operatively moveable. Magazine catch spring 224 may operatively install on and/or at least partially within magazine release button 222. Magazine catch spring 224 may install in the right side of lower receiver 210 and be covered and/or contained by magazine release button 222. In this regard, magazine release button may reciprocally move relative to lower receiver 210, in response to being depressed and/or compressing magazine catch spring 224. This configuration may be similar to the typical configuration found in a standard or mil spec AR-15/M-16 style rifle. Magazine catch spring 224 may compress and then rebound in response to the user depressing and then releasing or minimizing the pressure exerted on magazine release button 222.

In various embodiments, magazine release button 222 may operatively couple to and/or engage magazine catch 226. An actuation rod 227 of magazine catch 226 may install through lower receiver 210 through magazine catch spring 224 to seat and/or be actuatable by magazine release button 222. In this regard, pressure on and/or actuation of magazine release button 222 may cause magazine catch 226 to actuate radially outward from lower receiver 210 and/or radially away from lower receiver 210. This would allow a magazine to drop free and/or be removed from the magazine well.

In various embodiments, ambidextrous magazine release button 228 may also be operatively coupled to and/or may operatively contact magazine catch 226. Ambidextrous magazine release button 228 may be operatively installed in lower receiver 210. Moreover, ambidextrous magazine release button 228 may be secured within lower receiver 210 by pivot screw 229. In operation, ambidextrous magazine release button 228 may be configured to pivot about and/or actuate on the axis created by pivot screw 229. The pivoting and/or actuation of ambidextrous magazine release button 228 may cause magazine catch 226 to actuate away from the centerline of lower receiver 210 and away from magazine release button 222. In this regard, the magazine is releasable from either side (e.g., the right or the left side of the rifle).

In various embodiments, ambidextrous magazine release system 220 provides a user with a rifle with greater functionality and usability. Moreover, the rifle may be used, operated and/or reloaded easily by a shooter that is either right-handed or left-handed. Stated another way, the magazine may be released by actuating the magazine actuation system from either the right of the left side of the rifle and/or lower receiver 210.

In various embodiments and with reference to FIGS. 3A-3E, a bolt hold open system 330 is provided. Blot hold open system 330 may comprise a bolt catch 332, a bolt catch spring 334, a bolt catch plunger 336, a bolt catch actuator 338338, a return spring 337 and a retaining clip 339. Bolt hold open system 330 may be installable in an AR-15/M-16 style lower receiver 310. Moreover, bolt hold open system 330 may be configured, when installed in lower receiver 310 as part of a complete rifle 300, to retain a bolt carrier assembly 340 in upper receiver 315 in the out-of-battery position, as shown in FIG. 3E.

In various embodiments, bolt catch 332 may be operatively coupled and/or installed within lower receiver 310. Bolt catch actuator 338338 may be installed in lower receiver 310. Bolt catch actuator 338338 may also operatively couple to bolt catch 332. In this regard, bolt catch 332 and bolt catch actuator 338 may retained to one another with retaining clip 339. Moreover, bolt catch actuator 338 may be biased in the stowed position (e.g., the position where bolt carrier 3400 is allowed to cycle or be in the battery position as shown in FIG. 3D) by return spring 337. In this regard, when the bolt catch 332 is actuated (e.g., when bolt carrier 340 is released and allowed to more to the battery position) bolt catch actuator 338 may travel down and/or into the trigger guard.

In various embodiments, bolt catch 332 may pivot within lower receiver 310. When the bolt catch is engaged, the bolt catch 332 may pivot causing bolt catch plunger 336 to be contacted by bolt catch 332 and compress bolt catch spring 334. In response to bolt catch 332 being released and/or pivoted to the stowed position (e.g., allowing bolt carrier 340 to advance to the battery position), bolt catch spring 334 may bias and/or return bolt catch plunger 336 to the stowed position.

In various embodiments and with reference to FIGS. 3A-3E, in operation bolt catch actuator 338 may be installed in the trigger guard of lower receiver 310. This configuration may provide any user with an accessible, ambidextrous bolt hold open system. In this regard, a right handed or left handed operator may actuate the bolt hold open system may contacting the bolt catch actuator with a finger from the hand used to fire an AR-15/M-16 style rifle and/or actuate the trigger.

In various embodiments, bolt hold open system 330 may provide an operator with a way to safely and easily retain bolt carrier 340 in an out-of-battery position regardless of whether the rifle has ammunition and/or a magazine. In training and/or operational scenarios this may allow an operator to safely travel with, transport, and/or otherwise handle rifle 300.

In various embodiments, a firearm may comprise a firearm assembly tensioning system. The tensioning system may comprise a tensioning device that provides for adjustable tension between detachably coupleable components of a firearm, such as the lower receiver and the upper receiver of a firearm, when the components are coupled to one another. The tensioning system may be implemented or used with any suitable firearm comprising two detachably coupleable components.

In various embodiments and with reference to FIGS. 4A-4, a coupling mechanism may be selectively releasable so that firearm 400 may be moved between an assembled (i.e., coupled) position and a disassembled (i.e., uncoupled or partially uncoupled) position. In the assembled position, the lower receiver 410 is coupled to the upper receiver 415 so that the firearm 400 can fire a round or ammunition. In the disassembled position, the upper receiver 415 is at least partially separated from the lower receiver 410, such as, for example, by uncoupling the assembled firearm at a rearward pin and pivoting the components with respect to one another about a forward pin so that the firearm can be serviced and/or cleaned.

In various embodiments, a coupling mechanism may include pivot pin 412 (i.e., a forward pin) and takedown pin 413 (i.e., a rearward pin). Pivot pin 412 may pass through and operatively engage a pivot lug 416 of upper receiver 415. This configuration may provide that upper receiver 415 is rotatably coupled to lower receiver 410. Takedown pin 413 may pass through and engage a retention lug 418. When takedown pin 413 is installed in retention lug 416, lower receiver 410 is operatively coupled to upper receiver 415. In this regard, firearm 400 is assembled. However, the tolerance of various parts and/or wear on various parts may create and/or provide for movement and/or “slop” between upper receiver 415 and lower receiver 410. The movement may contribute to wear, may create a “rattle” or noise in the assembly and/or may be aesthetically displeasing.

In various embodiments, a gap 405 may exist between upper receiver 415 and lower receiver 410 when firearm 400 is assembled. Gap 405 may be defined between at least a portion of the mating surfaces of lower receiver 410 and the upper receiver 415.

In various embodiments, at least one of the lower receiver 410 or the upper receiver 425 may comprise a tensioning system 450 that may be used to adjust tension between lower receiver 410 and the upper receiver 415 when they are the assembled.

In various embodiments, tensioning system 450 may be installed in and/or may be a portion of lower receiver 410 and/or upper receiver 415. Tensioning system 450 may comprise one or more set screws 451/453 that are configured to bridge gap 405 between upper receiver 415 and lower receiver 410. For example, tensioning system 450 may comprise one or more with a nylon set screws 451 (shown as set screw 451-1, set screw 451-2, set screw 451-3, set screw 451-4, set screw 451-5, and/or set screw 451-6 in lower receiver 410 in FIG. 4C). Similarly, Tensioning system 450 may comprise one or more with a nylon set screws 453 (shown as set screw 453-1, set screw 453-2, set screw 453-3, set screw 453-4, set screw 453-5, and/or set screw 453-6 in lower receiver 415 in FIG. 4D). Set screws 451 may be installed in upper receiver 415 and/or lower receiver 410 in any suitable fashion. For example, set screws 451/453 may be installed symmetrically about a centerline of upper receiver 415 and/or lower receiver 410 in pairs. Any number of set screws 451/453 may be installed in upper receiver 415 and/or lower receiver 410. For example, a single set screw 451/453 or a single pair of set screws 451/453 may be installed in upper receiver 415 and/or lower receiver 410. In this regard, tensioning system 450 allows a user to adjust the movement out of firearm 400 by bridging gap 105. Moreover, tensioning system is adapted and/or adjustable as gap 105 changes due to wear, temperature, part replacement, part modification, part painting, and/or the like.

In various embodiments, each set screw 451/453 may be independently adjustable. In this regard, each set screw 451/453 may include a threaded length that allows a user to adjust the length of set screw 451/453 that protrudes from lower receiver 410 and/or upper receiver 415.

In various other embodiments, the size of a gap between two components may be dependent on the fit of the corresponding mating surfaces and/or the precision of the coupling mechanism used to detachably couple the two components. In accordance with various embodiments, the adjustability afforded by the components of the tensioning system described herein permits the set screw to be adjusted to securely engage the opposing surface of a coupled component.

In various embodiments, a component of tensioning system 450 may be removed from a firearm component or may be adjusted into a firearm component so that the tensioning device is flush with or recessed with respect to the mating surface of the firearm component in which the tensioning device is disposed. For example, set screw 45 may be removed from lower receiver 410, or set screw 451 may be threaded into lower receiver 410 such that surface set screw 451 is flush with or below the mating surface of lower receiver 410.

In various embodiments, set screw 451 and/or set screw 453 of tensioning system 450 may be made of a material that is elastically deformable in response to an applied compressive force. For example, set screw 451/453 may be made of any suitable polymer material, such as nylon, ABS, acrylic, polycarbonate, polyimide, and the like. Set screw 451/453 may be a material suitable to provide the desired elastically deformable properties under extreme environmental conditions, such as high and low temperature extremes, wet and/or corrosive conditions, and the like. In such embodiments, the protrusion of set screw 451/453 may be set so that a certain amount of force must be applied to compress the set screw before a coupling mechanism may be operated to secure two components. The opposing force provided by one or more set screws 451/453 of tensioning system 450 may provide tension between the coupled components at the coupling mechanism.

In various embodiments, set screw 451/453 may be a material that is plastically deformable or non-deformable (i.e., rigid). For example, set screw 451/453 may be a metal, metal alloy, hard thermosetting plastic, and the like. In such embodiments, the protrusion of set screw 451/453 may be set so that the set screw provides a positive stop for mating of a second component to the component in which the set screw is threadedly or otherwise engaged, at a point at which a coupling mechanism may be engaged to optimally secure the two components while minimizing free movement between the components that may be permitted by the tolerances of the coupling mechanism in the absence of the tensioning system.

In with various embodiments, set screw 451/453 may be configured to be turned or adjusted with a tool. For example, set screw 451/453 may comprise a socket configured to receive a Phillips screwdriver, a flat head screwdriver, a hex head wrench, a torx wrench, or the like.

In various embodiments, set screws with configurations other than those described above may be used. For example, a set screw having a protruding end with a frustoconical configuration may be used in a tensioning device and system of a first firearm component in accordance with various embodiments, and the frustoconical protruding end may be configured to be received within a corresponding relief machined into a coupleable second firearm component. In such an embodiment, a tensioning device and/or system may provide further lateral and axial stability in the assembled firearm, in addition to providing tension in the coupling mechanism in a vertical direction. Such set screws may comprise parallel surfaces and be adjustable with a cone wrench, for example. Other configurations of tensioning devices and attachment mechanisms ware within the scope of tensioning devices and systems of the present disclosure.

In various embodiments and with reference to FIGS. 5A-5I, gas block 560 may be coupled to the barrel of a firearm, such as an auto-loading rifle of the AR10, AR15 or M16 type (e.g., firearm 100 as described and depicted herein). Gas block 560 can be coupled to the barrel of the firearm though temporary, semi-permanent, and/or permanent means. In such embodiments, the barrel of the firearm is slid through barrel bore 519 of gas block 560, and gas block 560 is coupled to firearm barrel at a desired position along the barrel. For example, gas block 560 can comprise one or more screws, pins, or detents that align with corresponding dimples or holes in the barrel, allowing the gas block to be removed from the barrel. In other embodiments, gas block 560 can be welded, soldered, brazed, or otherwise permanently attached to the barrel of the firearm. Any manner of coupling gas block 560 with the barrel of a firearm is within the scope of the present disclosure.

In various embodiments, gas block 560 may be as part of a gas piston and/or gas impingement operating system.
