A selection of rather rough weapon concepts.
The KMP is a submachine gun developed in the European Union. It is an evolution of the old MP5 and UMP school of design, with the chief improvements being in materials, ergonomics, and durability.
It is a highly dependable weapon that performs well in any situation, and it's designed with reliability and heat dissipation in mind. The stock is both folding and retractable. The KMP is expensive, but, together with its predecessors, popular around the world, being relied upon by police and military forces in many countries including the Federal Union.
The DM4 is a submachine gun chambered in 5.8×21. Manufactured in the Celestial Empire, it uses a magazine based on the same principle as that of the FN P90. It's cheap and simple to manufacture, albeit unreliable and flimsy. Furthermore, there is no way to mount optics on it, and it has very little room for customization. Howver, it is adequate for arming large numbers of personnel for a low cost, and its ammunition is capable of penetrating basic body armor. In fact, the ammunition is surprisingly expensive compared to the weapon itself.
The KWK is a submachine gun chambered in 9x19mm. Originating in Iran, this SMG uses a helical magazine similar to that of the PP-19 Bizon. Although its magazine is not particularly reliable, it is favored for its high capacity and compact size. The KWK is reasonably cheap because it's manufactured in large numbers. Furthermore, it is somewhat customizable, and some models are equipped with rails. The original version came with a fixed stock that was attached to the grip, but subsequent versions have a more modular construction, with different stock possibilities. It has a threaded barrel and can mount a suppressor. One disadbantage of the KWK is its inability to mount a vertical foregrip.
The SAA-58 is a submachine gun chambered in the 4.6x30 PDW cartridge. Commissioned by the Caliphate's Arms Analysis Commission, it is produced in France, but is also licensed to several other manufacturers in the Mediterranean region. Although its ammunition is expensive, Egypt and several other Caliphate countries have embraced it as an SMG of the new era. In reality, its design is rather simplistic, and its chief accomplishment is simply being a cheaper alternative to other 4.6x30mm SMG's.
It uses a blowback mechanism, and its charging handle is on the left. Rails can be mounted on the front and sides, and it can be used without a handguard, or with various synthetic handguards, one with an integrated vertical foregrip. The standard stock is actually a top-folding adjustable stock, though this isn't particularly admired. Versions with other stocks exist. The receiver is opened by pushing on the side buttons around the takedown pin (it's vertical, and positioned on the top of the weapon, midway between the front and rear sights), which releases the pin and allows the upper, including the rear sights and stock, to swing backwards. This arrangement has led to some complaints of the weapon losing its zero, but in general these have been ignored, because the submachine gun is not expected to perform accurately at ranges where it matters.
Originally designated “GAA-4” during development, the DGF-2 is a grenade launcher fed by a drum magazine. It was developed as part of the same project that created the SAA-58, and fulfilled the Caliphate's Arms Analysis Commission's requirements for a portable grenade launcher. Its design principles are somewhat similar to the SAA-58, and it can use the same handguards, grips, and stock. There is also parts commonality in minor components such as buttons, pins, and trigger elements. It is manufactured throughout the Mediterranean, but on a smaller scale than the SAA-58, and is therefore less common.
The SARND SMG is a submachine gun chambered in 9x19mm. Part of the same project as the SARND Rifle, this weapon is originally of European design. Reasonably rare, it's only used by a handful of organizations.
Taking advantage of a unique feeding mechanism that allows the magwell to be positioned at the very back, these bullpups are masterpieces of ergonomics, once you get used to them. Generally they are quite accurate and easy to maintain, and the only problems they encounter are occasional misfeeds, and loss of durability from wear.
It fires 25mm grenade rounds and is suitable for a variety of applications, including police work performed with non-lethal ammunition.
The DGF-2A is an improved variant, which replaces the iron sights with a scope featuring an integrated rangefinding computer that properly accommodates airbursting rounds. Other improvements include durability and reliability enhancements, such as a sturdier charging handle, and a new stock. Although the traditional magazine is a drum magazine, the DGF-A2 can accommodate straight magazines as well, which are more portable, at the expense of ammunition capacity.
