First Assault Rifle Challenge - Gunbucket Scale

[Gollevainen]

A Gunbucket Challenge! Gunbucket is 20px : 1in
as it has been promised, so I hope the return rate is exelent this time.

Your Nation's FIRST assault rifle.

Assault Rifle here would mean:

• It must be capable of selective fire.

• It must have an intermediate-power cartridge: more power than a pistol but less than a standard rifle or battle rifle
  Typical intermediate cartridges have:
  • Necked cartridge
  • maximum service pressures range between 340.00–430.00 MPa (49,313–62,366 psi) Pmax piezo pressure
  • muzzle energies ranging between 1,328–2,455 J (979–1,811 ft⋅lbf)
  • Muzzle velocities ranging between 685–940 m/s (2,247–3,084 ft/s)
  • Relatively low O ratio's ranging between 4.29 and 7.99

• Its ammunition must be supplied from a detachable box magazine.

• It must have an effective range of at least 300 metres (330 yards).

Also this rifle needs to be the FIRST, with no preceding similar weapon in Service by the armed forces (or gun producer if you choose that direction) of your choosing.

Hi. This will be very interesting challenge. There are so many real life cartridges that have perfect match with the specs! . May I ask if there is any chronological boundary? Cheers!

[Gollevainen]

no chronological boundaries, but since this is the "first", your entry would require some presentation of how it is such.

I've had this done for about a week and couldn't decide what else to do with it

M1955 Machine Carbine:


Following the Second Great War, the United States found itself in dire need of a new semi-automatic rifle design to replace the bolt-action M1903 Springfield. The Confederate States had proven the effectiveness of its select-fire Tredegar Automatic Rifle chambered in the lighter 7.7x51mm "Confederate Short" rifle cartridge. As US forces captured innumerable TARs throughout the war and even found themselves issued captured examples in cases such as the Battle of Chattanooga, reverse-engineering the rifle seemed the obvious choice to pragmatists who had firsthand experience on both ends of its operation. Using original tooling captured at the Tredegar Iron Works in Virginia, initial experiments in simply rechambering the TAR to .30-06 failed due to the lighter pressure of the Confederate round. At the direction of Philadelphia, a new intermediate cartridge was developed to fill a similar role to .303 Confederate Short based on similar German Empire concepts for intermediate cartridges. Finalized as 7.62x46mm, the cartridge was simply a shortened .30-06 designed to work "superbly" with bolt-actions, semi-automatic rifles, and machine guns while retaining all of the same machinery. The M1945 Automatic Rifle was effectively an otherwise unmodified Tredegar Automatic Rifle chambered in this new cartridge, and first saw action in the Second Pacific War from 1948 to 1952.

Although highly successful in its own right, the M1945 was never intended to be a permanent solution for the US Military. A joint exercise between the United States and German Empire in 1950 gave a close look to the MKb-47, a development of the world's first "machine carbine." With a modern ergonomic design and intermediate 7.92x33mm cartridge, the MKb-47 proved extremely popular with soldiers given the opportunity to fire it and left a considerable impression on General Daniel MacArthur who became one of the strongest proponents for developing an American machine carbine. The official order to do so was given in 1953 after the surrender of Japan in the Second Pacific War, with prototypes from Winchester and Springfield accepted for testing by 1954. The Winchester Automatic Carbine was ultimately chosen for production and given the designation M1955. With a firing mechanism largely unaltered from the M1945, it was deemed the "safer" of the two designs and suffered no major malfunctions during testing.

The M1955 Machine Carbine is a gas-operated short-stroke carbine that fires 7.62x46mm ammunition. It replaced the M1945 Automatic Rifle as the standard-issue rifle in the United States Military in 1955 and although largely replaced by the M1971 remains in limited service to the present day. The M1955 saw service in every theater of war in the late 20th century from Peru to Liberia to the endless anarchy of central China, and in 1968 National Guardsmen carrying these rifles would fire upon a crowd of protesters at the University of Richmond in what would soon spark the Yankee Spring. As one of the most produced firearms in history, it was widely exported to over 40 countries across the world including the Confederate successor states, and is among the most popular civilian rifle patterns in the United States. The rifle was proven to be remarkably adaptable, with a number of variants being produced such as light machine guns, short-barrel carbines, marksman rifles, and lightweight paratrooper models.

M51/M92 Assault Rifle

The M51 became the standard issue service rifle of Antara from 1351, three years after the World War, derived from the MP46 fielded by Siegmaria during the conflict. The M51 was in service with the military for 70 years before being phased out with the carbine variant of the same weapon, as well as the M7.

The A1 variant featured rails that allowed for basic optical sights, as well as a M55GL grenade launcher with a dedicated handguard. The A2 variant had a retractable stock as standard issue, as well as rails on the handguard for attachments. The M92 is the carbine variant that superseded the M51.

AR-56

designed as a replacement for WWII vintage battle rifles the AR-56 assault rifle was Zipangs standard issue service rifle from 1956 to 2004, with the C-77 carbine variant still seeing some limited use by Zipang special forces


the cartridge that the rifle fired was the Zipang 6.35x53 cartridge which was originally developed for the cancelled type 1947 battle rifle. the weapon quickly proved itself to be very popular with troops, with a rate of Fire of 700 rounds per minute combined with the smaller cartridge then traditional rifles, meaning that it was easy to keep the rifle and target on full auto.

the rifle would be upgraded throughout the latter years of the 20th century resulting in the A1, A2 and A3 models each a iterative improvement, the rifle will also be developed into the C-77 carbine entering service in 1977 and and also being the only variant of the rifle that is still in service albeit in limited numbers.

Kassel-Werke Automatischer-Karabiner modell 1947 (AK 47)

In 1947, with tensions higher than ever between Aufzen and Morsig, urban combat on the heavily developed border region between the two nations was considered a top priority. The desire for a compact automatic weapon that lacked the range restrictions of contemporary SMGs led to the development of a new weapon by Kassel-Werke weapons designer (and Hymuth emigre) Mikel Savarian Varatiga, first tested in 1945. Using a lengthened version of the existing 9x20 mm Hannover cartridge, the weapon was classified as a "carbine," on account of its intermediate cartridge, and was designed as a bullpup (known as a Hinter-Vorwärds in Aufzenian terminology), intended to give the user more maneuverability in CQB. Accepted into service in 1947, manufacturing delays resulted in the first units not reaching troops until 1950. As initially designed, it had a 410 mm barrel, 600 rpm rate of fire, 20 round straight magazine, and operated using a gas operated rotating bolt.



In 1951 the final standard variant, the AK 47-51, entered production. Compared to the initial production run, the foregrip was replaced by a grenade launcher and bayonet was mounted on the barrel. Though it was popular among troops, it was only equipped by certain special forces units as well as Lowland units, and most units continued to use battle rifles. Its drawbacks, in that it was less potent and didn't have the range of the battle rifles mostly used at the time, and didn't have the capability to be modified to serve different roles like its battle rifle competitors. Approximately 50,000 examples were produced overall before production was stopped in 1961. In its final configuration, it was given a 40 round casket magazine over the initial design.



In 1970 the rifle was phased out of active service and was reequipped to reserve units as well as the Staatspolizei, the civil arm of the military's secret police. Though it's unknown exactly how many units were equipped with the weapon, numerous examples were modified to include an integral suppressor and IR scope to fit the needs of the police. Such units were designated as "Besonderen," or "special."



Edit: called it 9x20 Bauer when i meant 9x20 Hannover

Zk m/82

The first assault rifle officially adopted by the United Batavian Republics, the Zelfladende Karabijn model 1982 came about due to the Zürich Pact passing a motion to standardize on a new 6x40mm round in 1978. Unlike other armies, the Batavian Armies had never previously developed an intermediate rifle cardrige, relying on the 19th century vintage 6.5x51mm dutch round and the Zk m/64 which fired it until then. The standardization motion prompted the army to prototype a version of the m/64 in the new cardrige, while requesting a new generation infantry weapon from the Republikeinse Munitie Fabriek.

The new 6x40mm PACT round was smaller, much shorter overall and lighter than the 6.5x51mm dutch round, but it kept good ballistic performance through the use of a relatively long and heavy (7g, 105 gr) round and a broad case. First production rounds achieved 840 m/s speed and 2,390 J of muzzle energy, and depending on platform achieved 400 to 600m of effective range.

Though not standardized, there had been assault rifles issued to Republican Special Forces and Marine formations since at least 1965, predominantly of German, French and Louisiannean origin.



In 1979, trials were held between the m/64-79 prototype chambered in 6x40mm PACT, the German StG 77, the Swiss SIG SG 421 and the RMF prototype, which would later become the Zk m/82. Continental Army officers favoured the local RMF design overwhelmingly, whereas African Army officers favoured the StG 77, which was already in limited use by them. The trials were finally decided with imput from Navy and Eastern Army officers, and the RMF rifle was declared the winner in November.



The Zk m/82 sported an innovative bullpup configuration, enabling the use of a long 60 cm barrel while maintaining a compact package. A shorter version with a 45 cm barrel was soon developed as the m/82-83, to be used by vehicle crews, signallers and other positions that had till then used submachineguns, and was also adopted by the Navy for issue to boarding parties. The gun is cycled by a gas operated rotating bolt, the gas cylinder located above the barrel, and a regulator valve located on the front end of it. It was designed from the outset to fire rifle grenades like the previous m/64, so it features a hinged sight on the left side. A fire rate selector is located on the left side, in front of the magazine well, and has 3 positions, safe, semi-auto and full-auto.



The production version of the m/82 differs from the prototype by having a hinged cover for the gas cylinder valve regulator, a bayonet lug, a hook to connect a shoulder strap, fixings for a bipod, a hinged rifle grenade sight on the left side, a more robust stock bottom cover, and having its sights finished in matte. The m/82-83 cannot make use of a bayonet or bipod, and therefore has a smoother muzzle and no bipod fixings.

[Pantsu]

Good old FAL-esque. Feeds from a detachable 30 round magazine, with an AR-15 style magazine release on the right side (Although, there is no bolt release). The handguard, stock and the grip are made out of polymers (akin to the SG 553 rifle), and the C (corto/short) variant has a folding stock along with a shortened barrel for urban combat.
All rifles are fitted with only left handed fire selectors, and the rifle itself fires at Approx 700 rounds per minute through a short-stroke piston with a rotating bolt (Akin to the AR-18 series of rifles). As seen on the images, both the regular and the C variants fit a standard issue one-sided bayonet which was styled after the FNC bayonets.
Edit: Did two edits. Added some fluff about the rifle, plus fixed the template spacing.

RAK - 62
Schönberg Automatik Karabiniet, year 1962



After a it was decided by NATO members that a new gun was needed for its members, the choice was made to make the SAK-62 by cooperation between the United States, United Kingdom, France, Italy, Greece, Portugal and Yudonia, amongst other members.

It would first arrive to the battlefields by the Vietnam War International Intervention. Some years after, some NATO members ended up not liking the final result, and all of them scrapped it completely, leaving it for Yudonia to further improve and produce.
After that, the SAK-62 saw action during the Intervention in Lebanon and some other minor wars, over all around the middle east.

From there, and with a near perfect reputation about how uncommon were its jams, more than 80 thousand units have been produced for more than 10 countries, and it is still being used by some armies around the world, including Peru, Venezuela, Nicaragua, Indonesia and the Philippines. The gun would later be replaced by a heavy version of the HK416 around the 2000's, but wouldn't get out of service without the mottos of the "sucessfull gun" and "sakcess 62" by the Americans.
