PL-20 is a type of high-power, high-energy semi-automatic assault rifle, which was developed for the United States Armed Forces in the early 2000s. It is based on the M16A2 assault rifle, with modifications made to make it shorter and more compact. PL-20 fires 5.56x45mm NATO rounds, and can use a 30- or 40-round magazine. The weapon has a Picatinny rail system, which allows the attachment of various components such as sights, lasers, and flashlights. Its design also allows for the use of a suppressor and an M203 grenade launcher. PL-20 has been widely used by US military and law enforcement forces, as well as by other nations.
