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,[29] where the temperature would go as low as –20 degrees Celsius.[30] 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.[29][1] Similar complaints were also received from the Nepalese Army.[1] 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.[1]

Assault rifle
The standard issue rifle is produced in a select fire (semi-automatic & 3-round burst) version[31]. 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.[32] 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.[9] Additional furniture for the rifle is made, offering a folding stock.[33] It is being replaced in Indian service by the AK-203.[13]The AR has four subvariants:[34]
INSAS 1A
INSAS 1A1
INSAS 1B
INSAS 1B1: Further improved variant introduced in 2001 based on Indian Army feedback.[35]
