The AK is one of the most widely encountered rifles in the world and has been used by military and security forces in many different countries for decades. Because of its widespread use, personnel may encounter AK-pattern rifles in a variety of settings, including civilian AK retailers, professional environments, training situations, and while working alongside partner forces that use the AK. Every weapon experiences wear and tear and will eventually fail, even the AK. Regular cleaning and preventive maintenance checks and services (PMCS) are essential for avid sport shooters and any warfighter. Understanding the weapon’s condition, maintenance considerations, and common AK deficiencies can provide useful background for anyone who may encounter one. This article briefly covers the importance of preventive maintenance, inspection, and identifying potential faults to maintain equipment reliability and serviceability. This is for both civilians and those using AKs or training partner forces.
