Multi Caliber Individual Weapon System (MCIWS) is the new assault rifle developed by ARDE Pune of DRDO[1] and likely to be manufactured by OFT Trichy of OFB, India. It was first seen at the DEFEXPO 2014 exhibition.[2]

The Indian Army has decided to go for an indigenous assault rifle to replace the problematic INSAS rifles. The decision that could save thousands of crores in foreign exchange and boost local manufacture was taken recently by Army Chief General Dalbir Singh. The Army then cancelled a problematic Rs 4,848 crore order for importing Multi Caliber Assault Rifles on June 15-first reported by Mail on July 1.

The performance of the DRDO-designed 'Excalibur' assault rifle in trials last month at the Armament Research and Development Establishment (ARDE) in Pune has further enthused the Army. The Excalibur had only two stoppages (where the bullet gets stuck in the breech) after 24,000 rounds were fired, close to the Army's specifications of only one stoppage.

If the Excalibur/MIR clears trials, it could be in the hands of infantry soldiers within two years, DRDO officials say. The DRDO is designing a second version of the Excalibur, the AR-2 that fires 7.62×39mm rounds used by AK-47. The AR-2 will be offered as an alternative to the Russianorigin assault rifle.[3]

They are currently undergoing small arms trials[1] with three prototype rifles made for testing[4] as a future replacement to the INSAS rifle.[5] Trials are expected to last for six to eight months in 2013.[6]


The assault rifle is configured to fire in 5.56 NATO, 7.62×39 and in 6.8 Remington SPC.[2] Its design is influenced by both the AR-15 and the FN FNC.[2] The barrel assembly appears to be based on the AK-47.[7] The design would allow soldiers to configure it according to the needs of the missions by changing rifle barrels.[4] The MCIWS uses a gas operated short stroke piston design.[7]

The rifle would use 30-round plastic-type magazines.[5] It would also be ambidextrous features, such as the charging lever and magazine release.[5]

The MCIWS would include an underbarrel grenade launcher to fire airburst-type grenades.[2] Various sights can be mounted on the picatinny railing on the upper receiver.[5]
