Modular weapons are firearms designed with interchangeable components, allowing users to customize their weapon for specific needs or preferences. This modularity can include changing barrels, stocks, grips, and other parts, enabling quick adaptations for different situations, such as hunting, target shooting, or military operations. These systems enhance versatility and can improve performance by allowing users to tailor their weapon to various conditions. For example, a shooter might swap out a long barrel for a shorter one to increase maneuverability in close quarters. This adaptability makes modular weapons popular among enthusiasts and professionals alike.
