Built by the Grineer for their elite troops, the Vulkar is a devastating distance weapon. In the right hands it is capable of taking down targets long before they get into attack range.
The Vulkar is a Grineer version of the Snipetron, released in Update 8. It is equipped by Grineer Ballistas. Although almost identical in stats to the Snipetron, the Vulkar seems to be more accurate unmodded, and seems to be better for getting headshots or criticals.
It has identical reload sounds to the Snipetron, and the firing sound resembles the Ballista's sniper rifle. A close or medium range secondary is recommended to compensate for its bad short range capabilities, as with any sniper rifle.
Try to aim for the head or other vulnerable points only, take your time. Spraying and praying with this weapon does not work well, as with all snipers.
Reload as often as possible between fights.
Adding either a rank 2 Wildfire or a rank 2 Magazine Warp will give you 1 extra bullet. It's possible to have 2 extra bullets with a combination of Magazine Warp and Wildfire, however the sum of the effects of the mods must be 40% or greater, since the game sums the values before rounding them up.
