The chainsaw (GRA) is a weapon in the Fallout: New Vegas add-on Gun Runners' Arsenal.


The chainsaw is powered by a miniature nuclear battery that drives a toothed chain along a grooved bar at up to 8,000 RPM. This allows the sharp teeth to shred virtually anything they come into contact with. It differs from its standard variant in that it can accept modifications.

Special attackEdit

It has a special Scrap Heap attack, which does 50% damage in V.A.T.S. but at the cost of 20 fewer action points.

Note: Melee weapons do double normal damage in V.A.T.S.

It is not possible to execute Scrap Heap outside of V.A.T.S., as power attacks do not apply to continuously damaging weapons, such as this weapon and Ripper.


The chainsaw (GRA) can successfully strike about 7,995 times, or 11,995 times when equipped with the heavy duty chain, from full condition before breaking.

  • With the chainsaw alloy frame and the Heavyweight perk, this weapon ends up weighing a mere six pounds, making it far more practical to haul around than the standard chainsaw.
  • While noise from the chainsaw's blade and motor is audible, it is still possible to sneak near an enemy using a Stealth Boy without being detected.
  • This weapon can be used for the "Armed For Bear" challenge in the Gun Runners' Arsenal add-on.
  • A fully upgraded chainsaw, with all related perks, is the second strongest melee weapon in the game, only surpassed by the thermic lance.
