INSAS (an abbreviation of Indian Small Arms System) is a family of infantry arms consisting of an assault rifle and a light machine gun (LMG). It is manufactured by the Ordnance Factories Board at Ordnance Factory Tiruchirappalli, Small Arms Factory Kanpur and Ichapore Arsenal. The INSAS assault rifle is the standard infantry weapon of the Indian Armed Forces. It has been reported plagued by reliability problems. In April 2015, the Indian government replaced some INSAS rifles of the CRPF with AK-47s.
