INSAS is an abbreviation of Indian National Small Arms System. It is a family of firearms consisting of assault rifles, a light machine gun and a carbine, manufactured by the Indian Ordnance Factory Board. The INSAS Assault Rifle is the standard infantry weapon of the Indian Armed Forces. It's based on the AK-47 and FN FAL.
Persistent quality control and reliability issues prompted the rifles to be deemed defective in 2012 and pulled from issue in "red zones" in 2015 in favor of older and imported rifles as the Indian army searches for a replacement, which was later chosen in the form of the AK-203 and SIG-716i for the rifle version and IMI Negev variants for the LMG version.
