MODULAR Jlt1REARM BUTTSTOCK

This application claims priority from US Provisional Patent Application No 60470050 filed on May 13 2003 which is hereby incorporated herein by reference in its 5 entirety

BACKGROUND

The present invention broadly relates to the art of firearms and more particularly to a firearm butlstock adapted for selective mounting of related accessories and components

It will be appreciated that tbe present invention finds particular application in conjunction with firearms sucb as ARMALfTE AR15M16 rifle series models and COLT 15 CAR15M4 carbine series models and is sbown and described berein with specific reference to these weapons However it is to be distinctly understood tbat the present invention bas broader application and is equally applicable for use on many oiber sboulder fired weapon of various types makes and models For example tbe SUbject modular butlstock can also be used on FARRIQUE NAllONALE FAL SIG 5-series and HECKLER amp KOCH G-series rifles for exampeAUTOMAT KALASHNIKOV 47fi4 RODlNshySON ARMS M96 and HECKLER amp KOCH XMB carbines 25 for example and REMINGTON 870 MOSSBERG 500 and BENELU M3 SUPER 90 shotguns for example Accordshyingly the subject disclosure and reference to ARMAUTE and COLT models is nOI to be in anyway construed as a limitation of tbe present invention to sucb specific applicashytions

from the early days of firearm history shoulder-fired small arms bave had tbe ability to store items in small compartments usually located in the firearms buttstock From the earliest accounts dating back hundreds of years to 35

the use of matchlock flinllock and related firearms the butlstock of firearms have included a compartment to house various items such as fuses flints percussion caps and patches to aid the user in being prepared The intent was for the firearm lO function as closely to a self-ltontained unit as possible This lowered the chances of the shooter being caught off guard and without vilal firing components

With the progress of the last two hundred years or so modern firearm technology bas reduced the need for a compartment to house firing components More modem 4S firearms typically use a similar compartment 10 aid in tbe care of firearms with components such as firearm cleaning kits typically beiog stored therein

For example sboulder-fired weapons such as the MAUSER bolt-action systems of the late IBOOs to present and the AUTOMAT KALASHNIKOV Model 1947 (also known as AJ(47) use the buttstock to carry some of the components to aid in fieldstripping and cleaning ihe firearm These menlioned firearms also rely on an accessible area to house a bore-cleaning rod Usually located under the fireshy 55 arms barrel wilhin the foregrip tbe cleaning rod (usually in a similar length to the firearms barrel) is unobtrusive but easily accessible to aid in the firearms cleaning or to dislodge a srock cartridge casing that failed to extract under normal means

On some modem sboulder-mounled firearms the cleaning components are located al the rear portion of the buttstock just under the bUllplate Access to these components is obtaioed by removing the bullplale (by use of a latcb system) or through ao aCcess door located on the butlplate However 65

within Ihe last few decades most modern shoulder-fired weapons have eliminated the firearms capability to house a

2 cleaning kit or cleaning rod As mentioned above however some firearms do feature a compartment for accessing a cleaning kit or related tools and components This is often dependent upon the country of origin and Ihe particular use of the firearm

Currently tbe United States government and other westmiddot em countries use a variation of tbe ARMALITE Rifle model number 15 (also known as the AR15) In the United States inventory the improved version of tbe AR15 is the US rifle Model No 16 (known as Ml6) ALo used in the United States inventory is a firearm utilizing the AR15 charactershyistics but in a shorter form This carbine is known as Ihe US carbine Model NO4 (alSO known as the M4)

Even though the M16 and M4 are exact in function and somewhat compatible for parts interchangeability they both differ in storage capability The M16 features a trap door located in tbe buttstock which accesses a small compartshyment for the rifles cleaning kit The M4 carbine does not offer such a compartment because of its size and multiple uses The M4 bas a smaller bUlIstock whicb is collapsible to aid in making tbe firearms overall length smaller

This design was carried over originally from the early coer Automatic Rifle Model No 15 (also known as the CAR15) Making the firearm smaller is beneficial to help the shooter move safely and comfortably in confined areas or egnss from a ught opening such as an aircraft or a vebicle doorway The M4 buttstock is not only collapsible bul also includes various intermediate extended positions providing for an adjustable overall Iengtb of the firearm

The M4s buttstock telescopes along the carbines receiver extension which protrudes from the rear of tbe carbine The M4 bultstock has the ability to lock onto tbe receiver extension in multiple positions providing the adjustshyable leogth Ibis aids various sized shooters by belping 0

beller fit the firearm andor assist in shoulder mounting tbe firearm over top of webcombat gear that tbe shooter might be wearing

The M4 collapsible stock is in some cases considered to be too sbort even with it fully extended outward Also the stock is sometimes found to be uncomfortable against tbe face of the shooter when the same is placed against the cheek weld This is al least partly because of the uneven surfaces and sharp edges Ihroughoutthe top surfaces of the bultstock

Current military bultstocks in both the rifle and carbine configurations usually are of a basic design The manufacshyturers and buyers of firearms typically require very lillIe from the buttstock design As sucb other than comfort and strength the bUltstock has-few other requirements Since the development of tbe earliest shoulder-fired firearms the buttstock bas simply been there for support in aiming tbe weapon to transfer recoil aClion from the weapon 10 tbe shoulder of the shooter and to aid in the comfort of Ihe sbooter

During tbe early days of firearm development the goal was to get a projectile from point A (the fIrearm mU7zle) to point B (the target) the most accurate way possible In the last twenty years modem firearms are forced into new and unexpecled roles Tbis is true especiaUy for the military and law enforcement market Unfortunately tbe roles cbange depending on mission requirements So tbe modern combat firearms have become a mounting platform for a variety of accessories For example a number of companies have developed mounting platforms bat can be added to existing firearms or developed an integral mounting surface into the firearms construction These mounting platforms are usually located near the mU7~Jc end of the nrealTI1 This mentioned mounting platform is usually located on or

around Ihe firearms barrel and has the ability to mount a number of accessories such as lighting systems night vision hardware thermal imaging systems surveillance equipment and hardware 10 aid the user in achieving the best accuracy possible 5

With the array of items being mounted to the firearm a number of things occur First the area for placement of this mounting hardware is limited Second by mounting tbe hardware in the forward portion of the firearm the muzzle gets uncomfortably heavy Excess muzzle weight leads to difficult target acquisition Third the mounted components can in some cases need supplies to maintain reliable funcshytion Fourth the mounted component can be too large or complex to mount solely to the muzzle end of the firearm So the component may need to be dispersed tbroughoutthe 15 fireanu balancing the firearms overall weight A such it is desirable to develop a butlStock having the flexibility to mount additional accessories and provide mounting arrangeshyment for future use

One example of a modern buttstock that is known to have provisiollS for storing cylindrical objects sucb as batteries for example is disclosed in US Pal No 6543172 to Armstrong This butlSlock has an elongated central cavity and is supported on a firearm along that central cavity in a typical manner The bu tstock also includes an open-ended 25

passage extending longitudinally along each side of the butlStock parallel with the central cavity An elongated tube is received in each of Ihe passages and [onus a sliding fit tberewitb Tbe rubes each have one closed end and one open end An eno cap is used to seal tbc opcn end of eacb tube and tbereby form a sealed cavity for storage purposes

Such buttstocks however suffer from a number of shortshycomings and disadvantages that limit the utility of the same One disadvantage is that the passages that house the tubes are integrally formed on the hutlStock As a result the 3S

butlStock includes provisiollS for two rubes even in cases in whicb it is desired to use only one tube As such the exterior profile of tbe butlStock cannot be adapted or changed as mission requirements or personal preference dictate Another disadvantage is tbat the tubes comprise additional equipment componenlS that must be accounted for so tbat the device is functional in tbe first iostance and that must be properly secured to minimize the chance of tbe tubes being lost or producing a raU Ie or other noise Js sucb it is also desirable to develop a buttstock in which as many eompo- 45 nenlS as possible are secured to the buttstock frame 10

minimize the risk of loss while providing maxialum mountshying Ilexibility

shown with a modular bultstock 100 in accordance with the present invenlion assembled thereon Butllock 100 includes a buttslock frame 102 and a bullstock accessory sucb as a compartment 104 supported on the buttstock frame It will be appreciated tbat tbe buttstock frame is skeletonized to 5 have a minimal mass and is suitable for use as a bare slock without any attachments The bultstock frame acts as a bare mounting platform and can be manufactured in any suitable length shape or configuration to best fit the application or use of the firearm

Examples of suitable buttstock accessories are sbown in FIGS 2-5 Compartment 1M shown in FIG 2 includes a compartment body 106 having a generally cylindrical passhysage 108 extending therethrough to form a compartment for storing supplies or other accessories for example A pair of J5

spaced-apart tabs 110 and 112 extends from body 106 and each includes a pair of mounting holes 114 Extending from compartment body 106 generally opposite tabs 110 and 112 are a plurality of locking fingers or teeth 116 Compartment 104 in FIG 3 is of shorter length but otherwise substantially identical to compartment 104 in FIG 2 As such it will be appreciated that buttstock accessories in accordance with the present invention can be of any suitable size or shape For example compartment 104 could be manufactured in varishyous embodiments each having a different passage diameter 2S

or wilh mulliple smaller diameter passages extending parmiddot allel to onc another As such compar1mcnts suitable for storing different use dependent supplies could be accommoshydated by simplY switching from one compartment configushyration to another

Oleek weld adapter 118 shown in FIG 4 includes an adapter body 120 but does not include a cylindrical passage extending theretbrough as in compartment 104 Rather adapter body UO bas a contoured outer surface 122 Spacedshyapar1 tabs 124 and 126 extend from body 120 and each 35

prone (laying down) position lbe standard configuration is traditional and is favored by most of the sbooting public

Buttstock 100 sbown in FIG 1 can be used in place of the standard buttstock that normally comes standard on an AR15M16 rifle The installation of the buttstock is done by first removing the original buttstock This is accomplished by unscrewing a fastener (not shown) located at the rear of the original bUllSlock and then sliding the original buttstock off receiver extension 14 A buttstock frame 102 is then slid over receiver extension 14 until first end 204 of the buttstock frame firmly and squarely contacls receiver 12 of rifle 10 Next depending upon the length of tbe buttstock and the lengtb of tbe receiver extension a buttstock spacer (not shown) can be inserted into passage 131 from adjacent buttplate 140 on second end 206 Duttcap 136 is inserted into cavity 138 in bUllplate 140 wbicb fills tbe remaining space in passage 131 and aligns flusb witb butt plate 140 By installing the fastener (not sbown) through hole 142 in buttcap 136 and tightening tbe same into the receiver extension to tbe proper torque specifications buttcap 136 will firmly compress the buttstock frame into the receiver of the firearm It will be appreciated that tbe foregoing discusshysion is equally applicable to buttstock 300

lbe sborter buttstock 500 shown in FIG 16 mounts differently than the longer buttstocks discussed above Like the original carbine collapsible stock buttstock 500 features a spring-assisted locking pin 608 wbich mounts the stock securely to receiver extension 14 of firearm 10 Located on the bottom side of receiver extension 14 are indexing slot 20 and indexing holes 22 24 26 and 28 It will be appreciated tbat different models of receiver extensions can bave a different number of indexing holes Spring-assisted locking pin 608 can be locked into any of the individual boles depending on the overall stock length desired by the sbooter For example the bole closest to tbe receiver of the firearm is tbe closed or collapsed position The hole at tbe far end of the receiver extension is for placing the stock in its furthest most extended position

To move buttstock 500 along receiver extension 14 or to remove the butlStock from the same spring-loaded pin 610 of spring-assisted locking pin arrangement 608 must be retracted from tbe indexing holes This is achieved with the aid of release lever 612 The release Icvcr is located toward a lower portion 614 of second end 606 of the buttslOck frame and works on a basic teeter-totter tbeory By applying pressure at one end of release lever 612 tbe lever will pivot in the center and tbe opposite end will travel tbe opposite direction This action in turn retracts spring-loaded pin 610 Jbis operation retracts tbe pin enougb to slide tbe stock along receiver extension 14 To remove the stock firmly grab the complete release lever and pull it downward and away from tbe stock until tbe complete lever assembly travels no further Keeping pressure applied to the lever assembly move tbe stock to the rear portion of the receiver extension until stock assembly is completely removed

Two different release levers are available for the sborter buttstocks 500 and 700 One shown in FIG 17 as release lever 812 is of a traditional style used on tbe standard style buttstock The otber style sbown in FlG 16 as release lever 612 is for use on the clubfoot style buttstocks The clubfoot version can work on either tbe standard or clubfoot buttslOck but not vice versa The clubfoot protrusion will interfere with the operation of a standard release lever The clubfoot release lever however with iLlt slotted or U sbape works around the clubfoot protrusion

As discussed in detail above longer bullstock frames 102 and 302 can also mount to a shorter receiver extension 14 for a carbine series firearm This feature offers tbe sbooter ability to bave a longer lengtb stock that tbe shorter butlstocks cannot provide This feature can improve the comfort level of the shooter when the face of tbe same is placed onto a cheek weld adapter versus being placed parlially on tbe receiver extension which is normal wheo firing a standard carbine style firearm Also the longer butlstock fur1her provides the ability to mouot in two locations ODe is a collapsed length where the butlstock is in abuHing engagement witb tbe receiver of the firearm and tbe other is aD extended length where tbe butlstock is space from tbe receivcr about Slio of an inch

Mouotiog a longer butlsLOck such as butlstocks 100 and 300 to receiver extension 14 of a carbine style firearm is different tbao the practice of mounting the carbine and rifle butlstocks discussed above When mounting a longer butlstock the buHcap 136 and associated fastener (not sbown) are not used iostead the longer butlslock mounts in a similar fashion to that of a shorter butlstock but by using a manually locking pin 194 as showo io FIGS 12-14 rather than a spring-assisted locking pin such as 608 and 808 mentioned above The manual lockiog pin includes a pin portion 198 that locks into an indexing hole in the carbinc receiver extension but is not spring assisled like the stanshydard carbine spring-assisted locking pin

lostalling a longer buttstock sucb as bullstocks 100 and 300 is done by sliding the butlstock frame onlo the carbine style receiver extension until the bullstock is almost conshytacting the receiver extension nut securing the receiver extension to the receiver Two locking ports 190 and 192 are provided on the web portion of the mounting rail and extend upward tbrough tbe frame into passage 131 tbat bouses tbe receiver extension Manual locking pin 194 installs into locking port 190 adjacent second end 206 of buttstock frame 102 and pio portion 198 of be manual locking pin locates and locks into indexing bole 22 on tbe receiver extension Witb tbe manual locking pin 194 inserted pivot lock portion 200 wbicb is pivotally supported on body 196 is rotated downward until it contacts a ramping surface (not shown) located witbin the locking port adjacent flange portion 160 of mounting rail 156 Finally pivot lock ponion 200 is forced aloog tbe ramping surface until the pivot lock portion travels completely througb the locking pan and pivot lock portion 200 can travel no farther At this point tbe manual locking pin is secure and the buttslock is locked into a fixed position on tbe firearm It will be appreciated that Ihe buttstock can be secured in otber positions on tbe receiver extension such as that shown in FIG 14 for example in whicb the overall length of the firearm can be lengthened by about lito of an ineh The removal of the manual locking pio is done by apply pressure to Ihe pivot lock portion from the other side of the buttstock until the pivot lock portion moves downward along the ramping surface The manual locking pin can thercafter be removed from the locking port

The manual locking pin bas an additional feature for reducing the possibility of inadvertent removal of the lockshying pin from the locking port Located on a tip (not shown) of pivot lock portion 200 is a security hole (not shown) 10

ooe preferred embodiment tbe security hole has a diameter of about 5jj(lO of an iocb and is suitable to receive a wire spring hairpin (not shown) In this embodiment the hairpin can have a diameter of about Iioo of an inch and be of any suitable length such as 151i6 of an incb The hairpin is instalJed on the pivot lock portion aDd kceps the same from backing out of tbe locking port within the butlstock

12 Buttstocks in accordance with the present inve~tion offer

multiple sling mounting positions on tbe buttstock Both the longer and shorter butlstocks offer conventional sling mounting provisions similar to those 00 an original carbine bUltstock The buttstocks bave one or more openings such as SIOIs 166 shown in FIG 8 for example on Ibe second end thereof T3ullstocks of the clubfoot style can include three or more venically spaced holes or Slols wbile those of the standard style commonly have two or more vcrtically spaced boles or S)OIs

The other way to mount a sling is with a detachable sling swivel Both loDger and shorter buttstocks are adapted to mount a detachable sling ambidextroumiddotsly Quick-connect sling swivels include features to interlock with a sling lock sleeve such as sleeves 216 and 616 respectively shown in FIGS 7 and 16 for example The sling lock sleeves are preferably anchored or otherwise integrally formed on the butlstock Two or more sling lock sleeves are commonly provided on each buttstock

The quick-conoect sling swivel such as swivel 164 shown in FIG 8 has a number of retractable ball bearings (not shown) By pressing a detent button 165 located on the sling swivel the ball bearings retract to allow the sling swivel to be removed from or installed into the sling lock sleeve If in one embOdiment the bUllstock is manufactured by injection molding the sling lock sleeve can be loaded into the mold before injection of the plasticcomposite material As witb the slots discussed above the sling lock sleeve will accept a quick-ltletacbable sling swivel on either side of Ihe bultstock ambidextrously
