History
History
• Illustration — Indian soldiers in combat with INSAS rifle during the Kargil War. The first combat use of the rifle was during the Kargil War in 1999. The development of the INSAS began in the mid-1980s, when the Indian Army released a general staff qualitative requirement for a new assault rifle to replace locally produced licensed copies of the L1A1 self-loading rifles, which the Army was using since 1961. The new assault rifle was to chamber it in 5.56×45mm NATO, unlike the L1A1 SLR rifle which is chambered in 7.62×51mm NATO. After studying several designs, the Armament Research and Development Establishment (ARDE) in Pune undertook the task of designing and developing India's first assault rifle. The development and user trials of the new rifle, INSAS, were completed by 1989 and entered into service in 1990. Originally, three variants were planned in the INSAS system: a rifle, a carbine, and a squad automatic weapon (SAW) or Light machine gun (LMG). In 1997, the rifle and the LMG went into mass production. In 1998, the first INSAS rifles were displayed at the Republic Day parade. The introduction of the rifle was delayed due to the lack of adequate 5.56×45mm ammunition, large quantities of which were bought from Israel Military Industries. The INSAS series rifles are the third generation of standard-issue rifle of the infantry of the Indian Army, following the Lee–Enfield.303 bolt action rifle (in service 1947–mid-1960s) and L1A1 Self-Loading Rifle 7.62 NATO semi-automatic rifle (in service 1961–1998). While the L1A1 was outdated by the 1980s but the INSAS was still under development, multiple derivatives of AK-47 were adopted, starting with around 12,000 Soviet-origin AK-47 (produced by the Izhmash) captured from insurgents, followed by purchasing the Czech-origin Vz. 58, Bulgarian-origin AR-M1 from Arsenal AD. The INSAS rifle saw limited use in the Indian Army's counter-insurgency operations in Jammu and Kashmir, but was extensively used by Central Armed Police Forces in combating Maoist insurgency.
Replacement
Replacement
The INSAS assault rifles are being replaced in the Army with the AK-203 assault rifles and the SIG 716i battle rifles. The LMG variant is being replaced with the IWI Negev. However, these rifles will remain in service with the police and other paramilitary forces and are being used as a replacement for the decades old bolt action Ishapore 2A1 rifles.
Design and performance
Design and performance
The INSAS is primarily based on the AKM but incorporates features from other rifles. It has a chrome-plated bore. The barrel has a six-groove rifling. The basic gas operated long stroke piston and the rotating bolt are similar to the AKM/AK-47. • Illustration — US Army soldier and Indian soldiers with the INSAS. The two types of INSAS assault rifle include the 1B1 (rear) and the original (front). It has a manual gas regulator, similar to that of FN FAL, and a gas cutoff for launching grenades. The charging handle is on the left instead of on the bolt carrier, similar in operation to the HK33. The fire selector is placed on the left side of the receiver above the pistol grip, it can be set to semi–auto, three round burst and full auto. To set it to safe, the selector has to be rotated all the way up, which will block the sear and prevent the rifle from firing. It has three modes of fire – semi-automatic, three-round burst and full automatic modes. The cyclic rate averages at 650 rpm. The rear sight lies on one end of the breech cover and is calibrated to 400 meters. The furniture is either made of wood or polymer. The polymer butt and forend assemblies differ from the AKM and are more similar to those of IMI Galil. Some variants have a folding butt. A bayonet can also be attached to it. The guns take 20 or 30-round magazines; they are made like the Steyr AUG and are made out of polymer. The 30-round magazine is made for the LMG version but can also be used in the rifle. The flash suppressor also accepts NATO-specification rifle grenades. Factory-made brass catchers can be installed on the INSAS to collect used brass, although there are reports of improvised brass catchers made from used bottles and wire mesh. In 2023, it was reported that Star Aerospace has offered parts for modernizing INSAS rifles, which are approved by the Ministry of Home Affairs. Among the upgrades included by SA consist of picatinny rails for sights and attachments, folding stock and rubber fore and pistol grips. The INSAS assault rifle was battle-tested in the 1999 Kargil War. The three-month-long war was fought in the high altitudes of the Himalayas, where the temperature would go as low as –20 degrees Celsius. During the conflict, the rifle encountered some problems, such as occasional, often serious stoppages, cracking of the polymer magazine due to the cold weather, and some other reliability issues, such as firing in full auto when set for 3-shot burst. Similar complaints were also received from the Nepalese Army. In the Kargil war, the INSAS proved neither reliable nor satisfactory for the Army. The Indian Army, which was used to the 7.62×51mm NATO round for almost three decades, was dissatisfied with the stopping power of 5.56×45mm NATO rounds.
Assault rifle
Assault rifle
The standard issue rifle is produced in a select fire (semi-automatic & 3-round burst) version. A telescopic sight and a passive night sight are available for the weapon system. It has a bayonet mount and furniture featuring mounting capabilities for the ARDE Under Barrel Grenade Launcher. The rifle is equipped with an adjustable gas block regulator which, when flipped up, acts as an iron sight for a 40mm grenade launcher. The flash suppressor has a blank-firing adaptor. Additional furniture for the rifle is made, offering a folding stock. It is being replaced in Indian service by the AK-203. The AR has four subvariants: • INSAS 1A • INSAS 1A1 • INSAS 1B • INSAS 1B1: Further improved variant introduced in 2001 based on Indian Army feedback.
Light Machine Gun
Light Machine Gun
The Light Machine Gun (LMG) differs from the standard rifle in possessing a longer range of 700 m, as compared to a 400 m range for its assault rifle counterparts. It has a longer and heavier barrel with revised rifling and a bipod. The LMG version uses 30-round magazines and can also accept the 20-round INSAS AR magazine. This platform features select fire between semi-automatic and fully automatic. Furniture is also made for the LMG, allowing for a folding stock. The LMG will be replaced with the Negev NG-7.

• Excalibur rifle • Amogh carbine • DRDO Close Quarter Battle carbine • Kalantak: The Kalantak micro-assault rifle, with a range of 300 m, is for close combat and personnel defence weapon roles. • Prototype Bullpup: Lieutenant Colonel Prasad Bansod, of Army School Mhow reverse-engineered an INSAS rifle to produce a bullpup carbine variant. Lt. Col. Bansod caught the attention of high-ranking Indian Army officers when he made the rifle in 2019. He reportedly did this in his spare time. The rifle was only made as a prototype example.
