Designed as a pair, these Grineer sidearms fire projectiles at a slower rate but with greater force and accuracy.

This weapon can be sold for Credits64.png 5,000.

All drop rates data is obtained from DE's official drop tables. See Mission Rewards#Standard Missions for definitions on reward table rotations. Drop chances are rounded to two decimal places, following the official drop tables repository.
Expected means a player can expect to obtain at least one of a drop every N attempts on average.
Nearly Guaranteed refers to the total number of attempts a player needs to obtain a 1 in 10^2,3, and 4 probability not to have recieved a single drop (99%, 99.9%, and 99.99% probability to have received at least one drop).
The combined probability of multiple drops is 1 - ((1-A%) * (1-B%) * ...) (add drops in same rotation)

  • The bolts shot are implanted, but do not puncture wherever it lands (including railings) like a nailgun should function. Due to this, you can sometimes kill a Shield Lancer through his shield.
  • Flying corpses deal the same damage as the killing shot, not the total damage they received.
  • Despite being an automatic weapon, it only has 210 rounds of ammo in reserve. Increasing the fire rate even with Lethal Torrent will cause players to quickly run out of ammo.


  • The magazine of the Gremlins moves up through the gun as it fires, much like the Soma.png Soma, and is ejected forcefully from the top when reloading.
    • The magazine for the Twin Gremlins is known to pass right through the player when reloading.
  • When used with HallOfMirrors130xDark.png Hall Of Mirrors, MirageIcon272.png Mirage's clones will forcefully eject the magazine; however, magazines will still be within the gun
    • The magazines also do not move when used as if fully loaded.
  • This is the first akimbo secondary weapon without a single variant.
  • The text at the bottom of each magazine Grineer B.svgGrineer U.svgGrineer L.svgGrineer L.svgGrineer E.svgGrineer T.svgGrineer S.svg   Grineer F.svgGrineer O.svgGrineer R.svg   Grineer Y.svgGrineer O.svgGrineer U.svgGrineer R.svg   Grineer F.svgGrineer A.svgGrineer C.svgGrineer E.svg roughly translates to "Bullets for your face", rather odd given that, as a nailgun, it only fires nails. The text at the top however, directly translates to "Obey", which is common propaganda for Grineer.
