Criterion Barrels 13,9" CORE, Mid-length Gas System, Chrome-lined

The barrels of the Criterion Barrels Core series are specially designed with tactical shooters in mind. These pipes have been developed to improve the weight distribution, balance and handling of traditional profiles, while providing better performance through smooth harmony and uniform heat dissipation. The Core series barrels are ideal for use with modern accessories such as LPVO optics, gun mount lights, silencers, night vision devices and IR lasers. These components improve the performance of the gun, but can increase the weight of the forend and reduce the performance of the shooter. Core series barrels remain light and fast, improving handling, balance and speed. They offer excellent performance and durability in demanding conditions, making them ideal for situations where mobility and performance are paramount.
