The present disclosure relates generally to firearms. In particular, but not by way of limitation, the present disclosure relates to systems, methods and apparatuses for a breakdown rifle.
Handguns have long been the weapon of choice when space is at a minimum. However, handguns do not compare in accuracy and ease of long range shooting to rifles and carbines. Over the years, many have devised various breakdown rifles and carbines that can be stowed in backpacks or small carrying cases. For instance, the M4 Survival Rifle, M6 Aircrew Survival Weapon, ArmaLite AR-7, Kel-Tec SUB-2000, and Kel-Tec SU-16 are just a few examples of breakdown rifles/carbines that have been developed. However, each of these have their disadvantages. For instance, another example breakdown rifle, the Marlin Model 70PSS Stainless Papoose Rifle, lacks a forend or handguard, making it less suitable for high precision applications due to inconsistent barrel harmonics and less comfortable for use during long strings of fire such as during training due to heat. This issue is exacerbated as caliber size increases since larger rounds transfer more heat to the barrel. Additionally, grasping a barrel directly can affect barrel harmonics and potentially reduce accuracy. As another example, folding breakdown firearms (e.g., the Kel-Tec SUB-2000 and Kel-Tec SU-16) typically fold at an axis near a rear of the receiver and consequently leave the muzzle of the firearm exposed and susceptible to damage, especially if carried in a backpack or other non-traditional carrying case. Although a shorter barrel (e.g., under 16″) on some of these firearms would help reduce exposure of the muzzle to damage, shortening the barrel length too much can change a firearm's federal classification (e.g., Title I v. Title II), thus increasing its cost and licensing requirements. Companies wishing to maintain mass market appeal of their firearms therefore typically avoid barrel lengths under 16″. It is true that some “covert” folding firearms such as the MAGPUL FMG-9, protect the muzzle in the stowed configuration, however, they tend to have very short barrels (which introduces the Title II downsides discussed above), and are thus better suited to close quarters firing than for medium to long range accuracy. Others, like the Ruger SR-556 Takedown, or Remington/Bushmaster ACR are stored in separate pieces, making stowage and transport more complicated than folding-style weapons. Some, such as the US Survival Rifle variation of the AR-7, stow multiple pieces of the firearm in the stock, and while this protects the components and provides a single small package for carry, it also requires that the firearm be separated into a greater number of pieces to facilitate such compact storage. Further, many of these designs are limited to .22 caliber or smaller caliber rimfire firearms. What is more, most of these breakdown weapons are custom designs and thus their features and function are specific to that individual design and are not easily implemented across a broad range of weapons.
Many of these breakdown weapons also attempt to use space in the stock to store extra ammunition or magazines. However, these attempts typically leave the ammunition or magazines at least partially exposed and those prone to impact and moisture (e.g., Kel-Tec SU-16 and the ADTAK RM-4). Others arrange magazines or cartridges longitudinally through a rear of the buttstock, but this means that only a single magazine or cartridge can be accessed at a time, and a complex reshuffling is required to use a second or third magazine or cartridge.
An exemplary stock assembly for a takedown firearm has a buttstock assembly, and a forend assembly removably couplable to the buttstock assembly at a first location and a second location. When the forend assembly is coupled to the buttstock at the first location, the forend assembly is positioned to support a barrel of the firearm in a longitudinal firing position. When the forend assembly is coupled to the buttstock at the second location, the forend assembly is positioned to support the barrel at an angle relative to the longitudinal firing position.
An exemplary takedown firearm has a stock assembly having (a) a buttstock assembly; and (b) a forend assembly removably couplable to the buttstock assembly at a first location and a second location; wherein when the forend assembly is coupled to the buttstock at the first location, the forend assembly is positioned to support a barrel of the firearm in a longitudinal firing position; and when the forend assembly is coupled to the buttstock at the second location, the forend assembly is positioned to support the barrel at an angle relative to the longitudinal firing position. The exemplary assembly also has a barrel removably coupled to the forend, the barrel having a barrel shank, the barrel shank configured to engage an aperture in the buttstock assembly when the forend assembly is coupled to the buttstock at the second location.
An exemplary method includes providing a stock assembly for a takedown firearm, the stock assembly having: a buttstock assembly, and a forend assembly removably couplable to the buttstock assembly at a first location and a second location. The exemplary method also includes coupling the forend assembly to the buttstock at the first location, wherein the forend assembly is positioned to support a barrel of the firearm in a longitudinal firing position. The exemplary method also includes coupling the forend assembly to the buttstock at the second location, wherein the forend assembly is positioned to support the barrel at an angle relative to the longitudinal firing position.
To overcome the challenges of breakdown rifles/carbines in the prior art, the present disclosure presents a breakdown or “backpacker” rifle comprising a stock assembly 102 and a forend assembly 104. The illustrated firearm 100 can be fired when in a deployed configuration (see
The stock assembly 102 can include a forend assembly storage cavity 110 (compare
There may be a plurality of variations of the cheek piece 116, a first illustrated in
The action assembly 112 may be removable from the stock assembly 102, and can include a trigger assembly, receiver, and bolt among other components. The action assembly 112 may be configured for use with .22 caliber rimfire rounds, although other calibers and round types can also be implemented with the stock assembly 102. The cheek piece 116 may provide a protective and optionally sealed (e.g., water tight) covering for a stock storage compartment 170 (not visible in
The forend assembly storage cavity 110 can be shaped to accept a forend 126 of the forend assembly 104 when the firearm 100 is in the stowed configuration. The forend 126 can be defined as a structure under the barrel and forward of the stock assembly 102.
The forend assembly 104 can include a barrel 124, the barrel 124 having a muzzle 108 at a firing end of the barrel 124. The barrel 124 can be between 16″ and 18.5″ or greater than 16″. In some embodiments, a shorter barrel 124 requiring NFA registration of the firearm may be included. The shorter barrel may be useful to store a sound suppressor (silencer) attached to the shorter barrel and still have the muzzle end of the suppressor protected similarly to a longer barrel. That is, although the Figures illustrate only a barrel 124 supported by the stock assembly 102, in some embodiments, the assembly 102 may support a barrel 124 and a sound suppressor. In some embodiments, a barrel coupled to another elongated mechanism may be supported. The forend assembly 104 can also include the forend 126 configured for coupling to and supporting the barrel 124 in the deployed configuration. In the stowed configuration the forend 126 can fit into the forend assembly storage cavity 110 and be releasably coupled to the stock assembly 102 via one or more releasable fasteners. At the same time, a rear end of the barrel 124 can be releasably coupled to the stock assembly 102 via a barrel receiver 128 (see especially
The forend 126 can include one or two buttons 130 or other release mechanisms that a user can depress in order to release the forend assembly 104 from the stowed configuration. In particular, depressing the two buttons 130 (one on each side of the forend 126) or otherwise operating whatever release mechanism is used, releases a coupling between the tang 118 and the front of the forend 126. In some embodiments, depression of the two buttons 130 or activation of the release mechanism may also be used to couple the forend 126 to the tang 118 and thereby place the firearm 100 into the stowed configuration. The coupling between the tang 118 and the front of the forend 126 will be detailed further relative to
In the illustrated embodiment, a bottom of the tang 118 is shaped to generally replicate or partially surround the barrel 124 (see especially
The barrel recess 132 may also be shaped to accommodate a widest barrel 104 diameter expected (e.g., a bull barrel), thus leaving a gap relative to smaller-radius barrels (e.g., a tapered barrel).
In some embodiments, an engagement between the tang 118 and tang insert 138 may be water-tight and/or include a water-resistant o-ring at a sealing juncture. Those skilled in the art will recognize that
Additionally, the firearm 100 can be shaped such that the muzzle 108 does not extend beyond a front of the stock assembly 102 (i.e., the forend-to-stock interface 106). This, in addition to the barrel's 124 angle helps to protect the muzzle 108 in the stowed configuration. While minor physical impacts to the barrel 124 are unlikely to cause accuracy-degrading damage to the firearm 100, even minor impacts to the muzzle 108 can greatly influence accuracy and even safety of the firearm 100 since the inside of the barrel 124 is exposed at the muzzle 108. To protect the cartridge chamber at the rear end of the forend assembly 104, or the forend assembly 104 side of the forend-to-stock interface 106, the barrel receiver 128 can be shaped and arranged to receive the barrel 124. In this way, the fragile barrel 124 interface that couples to the receiver can be protected as well as the inside of the barrel 124. The barrel receiver 128 can partially surround a portion of the barrel 124. In particular, and with reference to
Because a front of the forend 126 may need to be lowered after being released before the forend assembly 104 could be moved forward, and thus decouple the barrel 124 from the barrel receiver 128, the aperture 136 may be ovular and generally vertically oriented, such that the barrel shank 134 could pivot up and down within the aperture 136. In this way, the forend assembly 104 may first be released at a front 120 of the forend assembly storage cavity 110, then pivoted downward about a pivot point at the barrel receiver 128 or rearward thereof until the forend 126 cleared the tang 118, and then the barrel shank 134 may be slid out of the aperture 136 with the forend 126 moving forward but below the tang 118. In some embodiments, the barrel receiver 128 is made of a rubberized thermoplastic material. The barrel receiver 128 may have an ovular aperture or may simply flex with the barrel as the barrel 124 is rotated out. This describes the actions and movements for releasing the forend assembly 104 from the stowed configuration, and a reverse of this procedure would allow stowage of the forend assembly 104. However, for stowage, the two buttons 130 or other release mechanism may or may not need to be depressed or activated in order to stow the forend assembly 104. See
Thus, the forend 126 can releasably couple to a front 120 of the stock assembly storage cavity 110, and be released therefrom via operation of the release mechanism or depression of the two buttons 130, or another release mechanism. The forend 126 can also slidingly engage with a rear 122 of the stock assembly storage cavity 110, in particular via a sliding engagement between the barrel 124 (or a barrel shank 134 thereof) and the barrel receiver 128.
The forend 126 can include a first latching detent 140 that releasably interfaces with a notch 150 (see
At the same time, a tang locking tab 141 (see
The first latching detent 140 may include one or more springs 162 that bias the first latching detent 140 forward to cause part of the flange 142 to extend out of the aperture 143. The buttons can include fingers 164 that interlace and help the buttons 130 to remain aligned while moving toward and away from each other.
A stock assembly for a takedown firearm may include a buttstock assembly, and a forend assembly removably couplable to the buttstock assembly at a first location and a second location. When the forend assembly is coupled to the buttstock at the first location, the forend assembly is positioned to support a barrel of the firearm in a longitudinal firing position. When the forend assembly is coupled to the buttstock at the second location, the forend assembly is positioned to support the barrel at an angle relative to the longitudinal firing position.
The stock assembly may include a release mechanism for coupling the buttstock and the forend. The release mechanism may include a detent engagement between the buttstock and the forend and/or a lever engagement between the buttstock and the forend. The release mechanism may have a button and a detent engagement, the button configured to release the detent engagement when depressed. The release mechanism may include a plurality of buttons and a detent engagement, the buttons configured to release the detent engagement when depressed.
The buttstock assembly may have a storage compartment, the storage compartment having a detachable cheekpiece forming a top portion of the storage compartment, and a release mechanism for enabling detachment of the cheekpiece.
The buttstock assembly may have an aperture for receiving a barrel shank on the barrel and a passage for supporting the barrel, as most clearly illustrated in
A takedown firearm may include a stock assembly having (a) a buttstock assembly; and (b) a forend assembly removably couplable to the buttstock assembly at a first location and a second location; wherein when the forend assembly is coupled to the buttstock at the first location, the forend assembly is positioned to support a barrel of the firearm in a longitudinal firing position; and when the forend assembly is coupled to the buttstock at the second location, the forend assembly is positioned to support the barrel at an angle relative to the longitudinal firing position. The takedown firearm may include a barrel removably coupled to the forend, the barrel having a barrel shank, the barrel shank configured to engage an aperture in the buttstock assembly when the forend assembly is coupled to the buttstock at the second location.
With reference now to
The method 3300 may include operating a release mechanism to detach the forend from the second location on the buttstock assembly. The method 3300 may include storing a firearm magazine in a vertical orientation in the buttstock assembly. The method 3300 may include nesting the forend assembly in a storage cavity of the buttstock assembly.
