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 the 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 and magazine, which takes about 1 minute in the field, without the need for any specialized tools.[5][11]
