The AK-203 order was originally a licensed-production deal: kits and components came from Russia and were assembled at Korwa, with indigenous content rising in stages. Building a prototype in which every component and input material comes from Indian industry changes the nature of the programme, because the supply chain - barrels, receivers, springs, polymers, alloys - then sits inside the country and is not exposed to sanctions, shipping delays or a partner's own wartime demand. That is the practical meaning of indigenisation in defence production, as distinct from assembly. For the infantry soldier, the AK-203 replaces the INSAS rifle, moving the standard cartridge from 5.56x45 mm back to the heavier 7.62x39 mm round, which delivers greater stopping power at shorter ranges - the trade-off the Army chose after operational experience in counter-insurgency and high-altitude terrain.
