Holosun LS321G

Multi-laser aiming module for rifles with a visible green laser, an infrared laser and an infrared illuminator in a 7075 aluminium housing. It mounts to a Picatinny rail with a quick-release lever and shipped with a remote cable switch. Holosun has since replaced it with the LE321 series; the figures here are from the archived maker page.

Which firearms take this part

Studio

Every firearm this threads onto, resolved

Not a list the maker typed out: the answer comes from the interface this part needs and the mounts each firearm exposes, so it stays right when either one changes.

  • The reverse lookup on every part in the catalogue
  • Interface standards, platforms and fit overrides
  • The same answers through the API and the MCP server

Requires a signed-in GunSpec account on the Studio plan. The answer is computed per firearm, so it is not part of the public record.
