Vidhwansak (Sanskrit: "The Destroyer")[4] is an Indian multi-caliber anti-materiel rifle (AMR) or large-caliber sniper rifle manufactured by Ordnance Factory Tiruchirappalli. It can be used in the anti-materiel role for destroying enemy bunkers, lightly armoured vehicles, radar systems, communication equipment, parked aircraft, fuel storage facilities, etc. It is also effective in long-range sniping, counter sniping and ordnance disposal roles.[5]


The Ordnance Factory Tiruchirapalli in association with the Defence Research and Development Organisation developed an anti-materiel rifle Vidhwansak in November 2005.[6] The Denel NTW-20 rifle was used as a starting point for the design.[3] After all-terrain and all-weather trials, the user trials began in March 2006.[5] Production began in February 2007. After trials, the Border Security Force ordered 100 Vidhwansaks for use in the border areas.[7] These were supplied by October 2008.[8] The rifle has also been offered to the Indian Army and the National Security Guards.[1][5] However, the Indian Army chose not to bring the Vidhwansak into use as it did not meet the weight requirements.[9]

It is being sold at the cost of Rs 10 lakh (about $20,000) as of 2011.[10]


Vidhwansak is a manually operated, rotating bolt-action rifle. The barrel along with the receiver recoil inside the chassis frame against a damping system. The rifle is fed from a detachable box magazine that is inserted from the left side. The rifle can be quickly disassembled and carried in two man-portable packs, each weighing about 12 to 15 kg.[5] A muzzle brake is fitted on the end of the barrel which absorbs an estimated 50-60% of recoil. This is further supplemented by a buffered slide in the receiver. Vidhwansak is equipped with an 8X magnification, long-eye-relief telescopic sight with parallax adjustment. A 12X ballistic scope can also be attached.

The rifle has an effective range of 1,800 m (1,300 m for the 20 mm version),[5] while shots can be achieved even up to 2,000 m. The rifle is magazine fed, and reloaded through manual bolt action.


Vidhwansak AMR is one of few firearms to support 3 calibers with quick interchangeability (without completely disassembling and reworking the weapon). The Vidhwansak can be easily converted between the three calibers - 12.7 mm, 14.5 mm and 20 mm, by replacing the barrel, bolt, magazine and scope, which takes about 1 minute in the field, without the need for any specialized tools.[5][11]
