Vidhwansak, which is sanskrit for "The Destroyer", is an Indian made changeable multi-calibre anti-materiel rifle developed in the Ordnance factory in Tiruchirpalli.
The Rifle can be used for destroying enemy bunkers,lightly armoured vehicles and radar systems in the battle field even at a distance of 2000m.
It is not based on the South African Denel NTW-20 as speculated[citation needed], but is comparable to the said weapon in terms of caliber.
Comparing Vidhwansak to the Denel anti-materiel rifle, the rifle is much cheaper than the NTW-20 and also has multiple calibers and fires 12.7mm, 14.5mm and 20mm rounds compared to dual calibres supported by the South African counterpart.
It is also a unique weapon in being one of the only weapons to support 3 calibres with quick interchangability.
The development of Vidhwansak was completed in November 2005 and the rifle had been offered to the Indian army, BSF and National Security Guards.
