EdGI high-performance tuning barrel with an inside diameter of 6,01mmThis barrel made of special brass is manufactured in hours of manual work in the Philippines and has the smallest manufacturing tolerances and thus allows for barely achieved precision.With the help of a specially developed polishing technique, a mirror-smooth surface is created inside the barrel, minimizing the friction between barrel and BB.Due to the special alloy, the barrel is very stable and corrosion-resistant.Production steps:1. Cut the raw material to the appropriate length for each type of gun2. Before the barrel is cold-forge hammered, it is lapped with a special polishing bar, this can take up to 4 hours depending on the barrel length3. During cold-forge hammering special polished and hardened inserts are struck into the barrel to increase the inner diameter4. Straighten: After hammering the barrel is straightened again with a special machine, this takes at least 2.5 hours5. Turn the outer diameter: The outer diameter is now adjusted to 8.53mm (approx. 40 minutes working time)6. Straightening by hand: The barrel will be perfectly straightened again7. Re-lapping the barrel for about 2 hours to create the perfect mirror surface inside8. Cut to exact length9. Crown the Ends10. HopUp window is cut by milling cutter11. Milling edges are straightened and cleaned by hand (30 minutes labor)12. Polish the barrel from the inside (30 minutes), the mirror-finished surface is now finished13. Polishing of the barrel from the outside (30 minutes)14. Protective coating of barrel from outside15. Inspection / Quality control
