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.

The KAC LAMG is a light machine gun developed by Knights Armament Company. It features a short-stroke gas piston system with a patented dual recoil spring system.

It is significantly lighter than traditional squad automatic weapons, weighing under five kilograms. The weapon features a free-floating handguard with M-LOK attachment points. It was designed for maximum controllability in automatic fire with minimal weight.

The FN Minimi is a Belgian 5.56×45mm NATO light machine gun developed by FN Herstal. It is the basis for the U.S. M249 SAW and has been adopted by over 45 countries, making it one of the most successful light machine gun designs in history.
