MFS 2000 Inc

MFS 2000 Inc. is a Hungarian ammunition manufacturer located in Sirok. It was established in 1952 as Mátravidéki Fémművek (Matra Metal Works) and began to produce ammunition for the civilian market in the late 1950s. Initial military production declined during the 1960s and 1970s in favour of civilian production. The company produced military ammunition with a plant code of "23". Factory code "21" is also associated with the company.

MFS is one of a relatively small number of producers of commercial 7.62x39mm hunting ammunition.

In 2008, the company's ammunition featured indirectly in a controversy over supply of Afghan army and police forces by a contractor to the United States Army. Instead of higher-quality MFS ammunition, Miami-based AEY Inc. provided corroded Chinese surplus ammunition, leading to termination of the Army contract.
