AK2 is a popular term that often refers to the second version of the AK series of rifles, known for their reliability and durability. The AK series, originally designed in the Soviet Union, has been widely used by military forces around the world. The AK2 typically features improvements in accuracy and ergonomics compared to its predecessor. The AK2 maintains the same gas-operated, rotating bolt mechanism that characterizes the AK family. It is chambered for the 7.62x39mm cartridge, which provides effective range and stopping power. This rifle is favored for its simplicity and ease of maintenance, making it a practical choice for both military and civilian use.
