Why did we choose the AK203 though, why not the AK 15?(IK we wanted AK 103 and the Russians convinced them to choose 203, but we've made it a 103M anyway but still)
Was it cost or something else?
The decision process by the selection of AK203 is extremely shady, even by Indian standards.
There was no tendor, no RFI, no RFP released. Around 2017, a team of 'experts' from MOD visited various army manufacturers factories around the world. They got breifed by company executives there, tested the rifles at their in-house shooting ranges, and based on that they made the decision that AK-203 will be procured. Russian's apparently showcased their other models including AK-15 too, but the expert team liked AK-203 better due to its simplicity. This weapon was to be manufactured in OFB Amethi factory, ignoring the fact that OFB has two other products in the same category in two other factories (TAR in Trichy factory, and Ghatak in Ishapore factory).
After that the contract negotiating teams of both sides met and as usual with other deals, the Russian started asking astronomical prices for the rifles. Now the Indian side is trying to reduce the price, by omitting different parts of the rifles (which may be procured later in other contracts similar to T-90 scam), such that AK-203 has watered down to AK103. To further decrease the price, we may end up with a barebone AK-47 or just a bolt carrier group and decide to go ahead with the contract.
