👉 A lined weapon is a type of firearm where the barrel is lined with a layer of metal, typically steel or another durable material, to reduce friction and improve the weapon's accuracy and durability. This lining helps maintain a consistent barrel length, which is crucial for precise shooting, especially in military and law enforcement contexts. The lined barrel also helps to minimize barrel wear and tear, extending the weapon's operational life and ensuring reliable performance under various conditions. This design is particularly important for semi-automatic and fully automatic firearms, where maintaining consistent accuracy is paramount.
