The AK-74 is a semi-automatic assault rifle designed by Mikhail Kalashnikov, introduced in the 1970s as an upgrade to the AK-47. It is known for its reliability, durability, and improved performance over its predecessor. The rifle is chambered in 5.45 x 39mm, which enhances its shooting velocity and accuracy compared to the 7.62 x 39mm cartridge used in the AK-47.
