Overview
The FN Minimi is a Belgian 5.56x45mm NATO light machine gun designed by Ernest Vervier and manufactured by FN Herstal. Introduced in 1974, the Minimi was developed as a squad automatic weapon to provide sustained suppressive fire at the infantry squad level. The weapon employs a gas-operated, long-stroke piston system with a rotating bolt, firing from an open bolt position for optimal cooling during automatic fire. A distinctive feature of the Minimi is its dual-feed capability, accepting both standard M27 disintegrating link belts (typically in 100- or 200-round cloth or plastic assault packs) and STANAG magazines, providing exceptional tactical flexibility. The Minimi features a quick-change chrome-lined barrel system, folding bipod, and adjustable gas regulator. With a cyclic rate of approximately 700-850 rounds per minute from belt feed and up to 1,150 rpm from magazines, the weapon delivers effective suppressive fire out to 800 meters against area targets. The FN Minimi has been adopted by over 75 countries worldwide, making it the most widely used squad automatic weapon in the world. It serves as the basis for the US M249 SAW, the British L110A2, the Canadian C9 LMG, the Australian F89, and the Swedish Ksp 90, among many other national designations.

Notes
The Minimi Para variant features a shortened 349mm barrel and telescoping buttstock for airborne and special operations troops, reducing overall length significantly. The Mk 3 variant introduced in the 2010s features enhanced Picatinny rail systems, an adjustable buttstock, and improved ergonomics. The FN Minimi 7.62 variant chambers the larger 7.62x51mm NATO cartridge for greater range and terminal effect. The weapon's rifling can be either 1:178mm (M193 optimized) or 1:305mm (SS109/M855 optimized) twist depending on the variant and customer specification. The six-groove barrel with chrome lining in both bore and chamber provides extended service life. Licensed production has been established in Australia, Canada, Italy, Japan, Indonesia, Greece, Switzerland, and Sweden. The Minimi can be mounted on tripods for the sustained fire role or fitted to vehicle mounts as a secondary armament system.
Background
The Minimi's unique dual-feed system -- accepting both belt ammunition and standard STANAG magazines -- was revolutionary for a light machine gun and provided unprecedented tactical flexibility. When belt ammunition ran out, a rifleman could hand his magazine to the Minimi gunner to keep suppressive fire going.
