The SIG SG 530 was a Swiss assault rifle developed in the 1960s by Schweizerische Industrie Gesellschaft (SIG) to take the then-new M193 ball and M196 tracer .223 Remington military rounds. [1]
Development of the rifle started in 1963 as a joint project between SIG and Beretta. The latter had already cooperated with SIG on the production of the SG 510-4 rifle for Chile. Initial prototypes of the 5.56 mm rifle used the delayed-blowback operating system of the SIG SG 510. However, this operating system proved to be problematic with the relatively "weak" 5.56×45mm NATO intermediate cartridge, and the designers were forced to use a gas-operated, roller-locked system. In 1968, Beretta ceased development with SIG, and went to work on their own 5.56 mm rifle design resulting in the outwardly similar AR70, later known as AR70/223. Due to a lack of sales, SIG abandoned the SG 530 in the 1970s in favor of developing the SG 540 series.
A carbine is a long gun that has a barrel shortened from its original length. Most modern carbines are rifles that are compact versions of a longer rifle or are rifles chambered for less powerful cartridges.
A squad automatic weapon (SAW), also known as a section automatic weapon or light support weapon (LSW), is a man-portable automatic firearm attached to infantry squads or sections as a source of rapid direct firepower. Weapons fulfilling this role can be light machine guns, or modified selective-fire rifles fitted with a heavier barrel, bipod and a belt/drum-fed design.
Fabrique Nationale Herstal, trading as FN Herstal and often referred to as Fabrique Nationale or simply FN, is a leading firearms manufacturer based in Herstal, Belgium. It is currently the largest exporter of military small arms in Europe.
An automatic rifle is a type of autoloading rifle that is capable of fully automatic fire. Automatic rifles are generally select-fire weapons capable of firing in semi-automatic and automatic firing modes. Automatic rifles are distinguished from semi-automatic rifles in their ability to fire more than one shot in succession once the trigger is pulled. Most automatic rifles are further subcategorized as battle rifles or assault rifles.
INSASor Indian Small Arms System is a family of infantry arms consisting of an assault rifle and a light machine gun (LMG). It was designed by the Armament Research and Development Establishment and manufactured by the Ordnance Factories Board at its various factories. The INSAS assault rifle was the standard infantry weapon of the Indian Armed Forces for almost three decades.
A designated marksman rifle (DMR) is a modern scoped high-precision rifle used by infantrymen in the designated marksman (DM) role. It generally fills the engagement range gap between a service rifle and a dedicated sniper rifle, at around 300–600 metres (330–660 yd).
The Sturmgewehr 57 is a selective fire battle rifle designed by Schweizerische Industrie Gesellschaft of Switzerland. It uses a roller-delayed blowback system similar to the H&K G3 and CETME rifles. The AM 55 entered service in the Swiss Army with the designation F. ass. 57 7.5mm or 7.5mm Stgw. 57, with export variations constituting the SG 510 family of small arms.
The SG 550 is an assault rifle manufactured by Swiss Arms AG in Switzerland. "SG" is an abbreviation for Sturmgewehr. The rifle is based on the earlier 5.56×45mm NATO SIG SG 540.
The StG 45(M) (abbreviation of Sturmgewehr 45, "Assault Rifle 45") sometimes referred to as the MP 45(M), was a prototype assault rifle developed by Mauser for the Wehrmacht at the end of World War II, using an innovative roller-delayed blowback operating system. It fired the 7.92×33mm Kurz (or "Pistolenpatrone 7.9mm") intermediate cartridge at a cyclic rate of around 450 rounds per minute.
The Beretta AR70/90 is a gas operated assault rifle chambered for the 5.56×45 mm NATO cartridge, and is the standard issue service rifle of the Italian Armed Forces. The weapon is also designed to be fitted with a rifle grenade, and has grenade sights. The AR series comes in many variants such as the AR90, with a wire folding stock, for use by paratroopers.
A STANAG magazine or NATO magazine is a type of detachable firearm magazine proposed by NATO in October 1980. Shortly after NATO's acceptance of the 5.56×45mm NATO rifle cartridge, Draft Standardization Agreement (STANAG) 4179 was proposed in order to allow NATO members to easily share rifle ammunition and magazines down to the individual soldier level. The U.S. M16 rifle's magazine proportions were proposed for standardization. Many NATO members, but not all, subsequently developed or purchased rifles with the ability to accept this type of magazine. However, the standard was never ratified and remains a "Draft STANAG".
The SG 540 is a 5.56×45mm NATO assault rifle developed in the early 1970s by Schweizerische Industrie Gesellschaft of Neuhausen, Switzerland as a private venture primarily destined for export markets and as a potential replacement for the 7.5×55mm Swiss SG 510 automatic rifle known as the Stgw 57 in Swiss service.
The Beretta ARX160 is an Italian modular assault rifle manufactured by Beretta. Developed for the Italian Armed Forces as part of the Soldato Futuro program, the ARX160 was launched in 2008 as a commercial weapon system independent from the Soldato Futuro ensemble, complete with a companion single-shot 40×46mm NATO low-velocity grenade launcher, called the GLX160, which can be mounted underneath the rifle or used with an ad hoc stock system as a stand-alone weapon.
The SIG Sauer SIG516 is a semi-automatic rifle manufactured by SIG Sauer. It is an AR-15 style rifle chambered in 5.56×45mm NATO. Introduced in 2010, the SIG516 was discontinued as of 2019. A variant chambered in 7.62x51mm NATO, the SIG716i, remains in production.
The SIG MCX is a family of firearms designed and manufactured by SIG Sauer, produced in both selective fire and semi-automatic only models, and features a short-stroke gas piston system, which is inherited from the earlier SIG MPX submachine gun. The MCX is available in rifle, carbine, short-barreled rifle, and pistol configurations. The rifle was further developed into the SIG MCX Spear, which was adopted in its .277 Fury chambering as the XM7 by the U.S. Army in 2022.
The CAR 816, also called Caracal Sultan or simply Sultan, is a 5.56×45mm NATO, gas-operated, magazine-fed assault rifle that is produced by Caracal International in Abu Dhabi, United Arab Emirates. The rifle is also called Sultan in memory of the Emirati Colonel Sultan Mohammed Ali al-Kitbi who was killed in action in Saudi-led intervention in Yemen.
The FFV 890 was a Swedish assault rifle manufactured and designed by Försvarets Fabriksverk. The FFV 890 was based on the Israeli IMI Galil through a manufacturing licence, which in turn was based on the Finnish Valmet RK 62 and ultimately the Soviet AK-47. The FFV 890 was designed between 1975 and 1980, and its final iteration, FFV 890C, competed in the Swedish Armed Forces trials for the new 5.56×45mm NATO assault rifle, where it ended up as a runner-up to the FN FNC, which was then chosen as the Ak 5. The FFV 890C was never widely adopted by any service, though some rifles were used by the Swedish police.
