The Stoner 63 is a modular weapon system designed by Eugene Stoner in the early 1960s. It was one of the first truly modular firearm designs, capable of being configured as an assault rifle, carbine, light machine gun, or belt-fed machine gun. The most common configuration was the light machine gun variant used by US special forces during the Vietnam War. The weapon is chambered in 5.56x45mm and uses a unique gas-operated piston system. The Stoner 63 was manufactured by Cadillac Gage and later by Colt.

The Negev is a modern Israeli gas-operated light machine gun manufactured by Israel Weapon Industries (IWI). It is chambered in 5.56x45mm NATO and features a quick-change barrel, a folding stock, and a Picatinny rail system for optics. The Negev was designed to replace the aging FN MAG in Israeli service while offering a lighter, more portable platform.
The M249 Squad Automatic Weapon is the U.S. military designation for the FN Minimi, a belt-fed light machine gun chambered in 5.56x45mm NATO. Designed to provide squad-level suppressive fire while maintaining parts commonality and ammunition compatibility with the M16/M4 family, the M249 operates on a gas-operated open-bolt system with a quick-change barrel feature. It can feed from both linked belts (stored in a 200-round box magazine) and standard M16-style 30-round box magazines, though the magazine feed is considered an emergency capability and is generally less reliable than belt feed. The M249 includes a folding bipod, a carrying handle, and a tripod mounting point for sustained-fire applications. At 7.5 kg loaded with 200 rounds, the SAW represents an ideal balance of portability and firepower for infantry fire teams.
The RPK (Ruchnoy Pulemyot Kalashnikova) is a squad automatic rifle derived from the AK‑47 family, designed to provide sustained fire support while retaining the rugged simplicity of its assault‑rifle counterpart. Developed by the Kalashnikov Design Bureau in the early 1960s, the RPK features a longer, heavier barrel, reinforced receiver, and a bipod, enabling higher rates of fire and improved accuracy at the squad level. Chambered primarily in 7.62×39mm, it uses the same gas‑operated, rotating‑bolt system as the AK‑47 but with a heavier bolt carrier and a larger gas piston to handle the increased heat. Its reputation rests on exceptional reliability under adverse conditions, ease of maintenance, and logistical compatibility with standard AK magazines and ammunition, making it a staple in Soviet and Warsaw‑bloc forces. The weapon’s distinctive features include a stamped steel receiver with reinforced ribs, a detachable steel bipod, and a unique muzzle device that can accept a flash suppressor or a rifle grenade launcher, underscoring its versatility as both a light machine gun and a rifle grenade platform.
