Thanks to an innovative system involving an increase in the barrel’s muzzle diameter and the addition of special grooves, the BB gains additional accuracy and range. The barrel therefore has two diameters:an inlet diameter of 6.03mm and an outlet diameter of 6.35mm. T.N.T. barrels are manufactured on high-precision CNC machine tools, ensuring high quality and accuracy.
In addition to the barrel and chamber, the set includesa high-quality, dedicatedHop-Up rubber with a hardnessof 60o.
The use of a high-quality barrel and Hop-Up rubber will improve the replica’s accuracy and range.
