Fluted barrel

**Fluted barrel**

A fluted barrel is a type of firearm barrel design characterized by longitudinal grooves, or flutes, cut into the exterior surface. These grooves reduce the barrel’s weight while maintaining structural integrity and increasing surface area, which helps with heat dissipation during rapid firing. Fluted barrels are commonly found on rifles and handguns, offering improved balance, reduced overall weight, and enhanced cooling performance. This design is popular among shooters who value precision and handling efficiency.
