The Tsingtao Type 16 submachine gun is a Chinese copy of the SIG Bergmann M1920 manufactured at the Tsingtao Iron Works Factory, unlike most other Chinese copies of the weapon it has a vertical magazine well. It used a 30 or 50 round box magazine and chambered in 7.63x25mm Mauser.
The AO-27 is a Soviet select-fire, gas-operated assault rifle, Designed by D.I. Shiryaev in 1961. The assault rifle is chambered with an original 7.62/3 mm OPS flechette sabot round.
Tests shown excellent flatness and penetration of the flechette sabot rounds, but also, a slightly lower accuracy, comparing with common rounds.
- The Rifle à Forte Cadence de Tir (lit. "rifle with high rate of fire") was a prototype French high rate of fire assault rifle designed by Etablissement de Fabrication d'Armement de Bourges in 1975. A prototype rifle designed by EFAB based in Bourges, France, the RFCT was an experiment to design a rifle with a high rate of fire.
- The rifle was designed in 1975 by designers at the Etablissement de Fabrication d'Armement de Bourges, a predecessor company of GIAT Industries (now known as Nexter). Two rifles were produced as a proof of concept to design an assault rifle with an extremely high rate of fire; one rifle was for cased ammunition (5.56 × 45mm NATO) while the other was for caseless ammunition. The project was quickly shelved when it was discovered that the weapons were very user-unfriendly, being difficult to chamber and nearly impossible to control.
- The RFCT was essentially a barrel mounted on a stock and frame in a rather crude fashion. The weapon is said to operate quite similarly to an M61 Vulcan. The weapon used a rotating six-round cylinder. The weapon's rate of fire is extremely high at 4000 rounds per minute, or about 67 rounds per second.
- The G11 (name unofficial) was a West German prototype assault rifle based on a 1974 patent by Industrie Werke Karlsruhe (IWK), an associate company of Mauser.
- The Mauser G11 is a bullpup rifle, which was fed through an internal 10-round helical-loading magazine, chambered in caseless 4.75×21mm or 4.3×18.5mm and loaded into the weapon through a port on the side by the use of stripper clips. Cartridge moved from the magazine to the barrel's chamber by a rotatable star mechanism. This design makes the rifle compact, protects the ammunition from eternal elements, and ensures reliability. Also, a safety mechanism secures the trigger during loading, preventing accidental discharge. The cyclic rate of the rifle is speculated to be around 1500 rounds per minute with a muzzle velocity of 1000 m/s. The weapon also features a topside charging lever similar to those on early AR-pattern rifles.
- In 1978, a physical prototype was constructed and tested by NATO, but failed to meet expectations. Therefore, the gun struggled to gain traction and the entire Mauser's project was transferred to Heckler and Koch. This resulted in the development of the more successful H&K G11 caseless assault rifle.
- The Armtech C30R was an assault rifle concept made by Armtech's LTD from Australia to join into international market. It used a 60-round internal pan magazine via rotary-breach action, and chambered in caseless 5.56mm ammunition with specific dimensions (Quadrant with 3.56g standard M193 bullet, dimensions of the rectangular ammunition 35.7×15.8×9.5 mm) similar to the H&K G11.
- Although the concept of the C30R was highly publicized in Australia, it was developed in haste and premature demonstration before full development in front of news media led to the worst nightmare of the gun developer - poor reliability and an explosion while the rifle was being test fired, apparently an "out of battery ignition."
- This disaster led eventually to the demise of Armstech, but not before the firm had decided to pursue a conventional rifle with the basic features of the C30R. The company went into receivership in 1990, after having transferred rights to the rifle to Keith Greenwood of Edenpine, where it was developed into the SAK-30 and ART-30, the direct ancestor of the M17S (The salient features of the M17S were in place but some Finnish Valmet parts were used instead of AR-15 parts to save money).
- Seeking broader markets, especially the US, an agreement was reached with Bushmaster, who completed development of the rifle, re-designated it as the M17S and began producing it for domestic sale from 1992 to 2005.
- In 2004, a hacker group called "The Flexilis" attended the 12th annual DEFCON conference in Las Vegas with a new homebrew weapon called "BlueSniper Bluetooth Sniper".
- The BlueSniper is a rifle stock with a scope and yagi antenna attached. A cable attaches the antenna to the Bluetooth card, which can be in a PDA or laptop computer. The laptop can be carried in a backpack with the cables connecting into the backpack, giving it the Ghostbusters look.
- The weapon can detect Bluetooth devices through wall and attack them from a distance.
- The Soldier Integrated Precision Effects Systems (SIPES) is a project initiated by the Canadian Armed Forces (CAF) in collaboration with Defence Research and Development Canada (DRDC) and Colt Canada.
- The SIPES prototype is a bullpup-configured rifle designed to fire 5.56mm cased telescoped ammunition. It includes a secondary effects module that can be configured as a three-round 40 mm grenade launcher or a 12-gauge shotgun, providing multi-role capabilities.
- A NATO standard power and data rail integrates various accessories such as electro-optical sights and position sensors, reducing the need for multiple power sources and minimizing the soldier's load.
- SIPES features automated target detection and geo-location sensors, allowing the weapon to share data with command and control networks for improved situational awareness and combat efficiency. A heads-up display provides critical information such as target distance and remaining ammunition.
- The SIPES project was intended solely as a technological demonstration of potential advancements for the CAF. It was never meant to be put into production.
- The TVGK or TГBК in Russian, standing for "тяжёлый гранатомётно-винтовочный комплекс" or "heavy grenade-rifle complex" is a conceptual weapon system that combines assault rifle with a grenade launcher. It was developed by KB Shar in Ukraine in the early to late 2000s.
- The assault rifle component of the TVGK features two horizontally aligned barrels of chambered for its proprietary 4.92x34mm rounds from a 70 round box magazine. Each barrel of the rifle has its own firing mechanism, allowing for a staggered firing sequence similar to the AO-63, a twin-barreled assault rifle where each barrel fires with a slight delay (in the hundredths of a second) to prevent interference between the bullets in flight. The rifle has a dual-rate of fire mechanism, with selectable firing rates of 500 or a theoretical later proven burst fire rate of 8000 RPM.
- The grenade launcher component, which places under the rifle's barrel, fires 20mm low-ballistic grenade from a 5 round box magazine.
The reason why the gun was spinning because they set up the gun a bit tilted to the right, causing the gun to spun when fired.
In the early 1950s, Izhmash engineers began looking for a hybrid concept that could capture the SKS’s semi automatic accuracy and the AK’s fully-automatic capability. The idea was to give the AK improved automatic accuracy performance without sacrificing its famed reliability. This led to the development of a series of Kalashnikov experimental rifles starting in 1952 and later refined in 1955-1956, which was called the Automatic Carbine or Assault Carbine. One of the biggest changes was to the operating system; its gas system was moved rearward and used a short-stroke piston system.
It had a flame range of up to 15 feet. Its primary mission was to surprise the enemy, making it easier for the user to close in. In reality, however, it was quite heavy, and the user was more likely to be frightened by the weapon itself than the target was.
