A 7.62mm coaxial machine gun 6P7K is coupled to the 125mm gun. The 2A46M-5 gun design made it possible to reduce the technical dispersion of shells of all types by 15% on average and to increase the effective range of fire. The main armament of the T-90MS includes a 125mm high-accuracy gun 2A46M-5 with new features such as the installation of a high-rigidity barrel tube, play-free trunnion assembly units with elastic rollers and return wedge and two additional play take-up elements with rollers.

The weight of the T-90MS has increased by 1,500 kg, compared to the basic model of the T-90 to reach 48 tons, but it remains significantly lower compared to the German main battle tank Leopard 2A6 and the American M1A2 Abrams. In April 2019, India’s Cabinet Committee on Security (CCS) approved the INR134.48 billion (USD 1.93 billion) procurement of 464 Russian-made T-90MS main battle tanks (MBTs) for the Indian Army (IA), the New Delhi Times reports. According to a news published on November 8, 2019, to the official website of the 'Times of India', the Indian Ministry of Defense has signed a contract with the Heavy Vehicles Factory at Avadi in Chennai to produce 469 Russian T-90 Main Battle Tanks (MBTs), that could be the MS version of the T-90 family. This new tank is a complete modernization of the T-90 by touching all the characteristics of the basic variant to increase its operational capabilities in combat and against modern threats on the battlefield. The new T-90MS was presented for the first time to the public during the defense exhibition Russian Expo arms in September 2011. The T-90MS is the next step in the development of the Russian-made main battle tank T-90.
