UFM KeyMod System for AKM Rifles, Long Version

6061-T6 aluminium AK handguard system with KeyMod slots and a 1913-style top rail that returns to zero after tool-less field stripping, keeping the factory fore-end flange on stamped receivers. Not for milled receivers or the 54R Vepr. Replaced in the Krebs catalog by the M-LOK fore-end for AKM rifles.

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.
