In Musket Testing / artillery-style Roblox games, the bayonet is usually not “removed” permanently —it’s toggled off or detached through the weapon controls. The most reliable control I found is B to attach the bayonet and X to use it on the musket, with some guides showing the same controls in both first-person and third-person modes.

What to try

  • Press B again to see whether it detaches or toggles the bayonet off.
  • If that does nothing, switch weapons or respawn, since some games only let you unequip it by changing loadout.
  • On mobile, look for the bayonet button in the weapon UI, because one guide notes mobile uses on-screen controls instead of keyboard keys.

If it still stays on

  • The game may not support full removal, only attach/detach during play.
  • Some players treat it as part of the musket model rather than a separate item, so there may be no true “remove” option in that mode.

Quick answer

For most cases, try B to toggle the bayonet off, and if that fails, change loadout or respawn because the game may lock the bayonet to the musket.

TL;DR: press B first, then try switching weapons or respawning if the bayonet won’t come off.
