About

What it is, and why it matters

Copy a link to this section

The KMG556 is a Turkish 5.56x45mm NATO light machine gun developed by Kale Kalip as a clone of the FN Minimi (M249). It is a gas-operated, belt-fed weapon firing from an open bolt, fed from 50, 100, or 200-round disintegrating metallic-link belts, and uses a quick-change barrel. Unlike the original Minimi, it feeds only from belts and not from STANAG magazines. The KMG556 features newly designed polymer furniture including an adjustable buttstock and forend, and was Turkey's first NATO-qualified domestic 5.56mm light machine gun.

First documented in combat in Ukraine in mid-2024 with the National Police's Lyut Brigade, the KMG556 became one of the more visible Turkish-made support weapons of the Russo-Ukrainian War.

Marketed as the first and only Turkish-made 5.56x45mm light machine gun qualified to NATO test standards. Standard barrel is 16 inches (406 mm), with 14.5-inch and 18-inch barrel options offered.

Studio

Every part that mounts on this, resolved

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

  • Every part that mounts on any firearm 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 part, so it is not part of the public record.
