👉 A modular weapon is a highly adaptable and customizable firearm design that allows users to easily swap out various components, such as barrels, magazines, grips, and even ammunition types, to suit different tactical needs or personal preferences. This modularity enhances versatility, as users can quickly upgrade or modify their weapon to match changing combat scenarios or personal requirements. By enabling quick adjustments without needing a completely new firearm, modular weapons offer significant cost savings and flexibility in modern military and law enforcement applications.
