Chamber is milled on CNC milling machine and it also has protective anodizing of 5µm silver colour (0,005mm).\u003c\/span\u003e\u003c\/b\u003e\u003c\/p\u003e \u003cp\u003e\u003cb\u003e\u003cspan style=\"font-size: 18px; line-height: 106%; color: black;\"\u003eWe build this Hop-Up chamber on results from testing, so this chamber is precise and custom-made constructed for best feeding and performance. We changed drill depth, so with 20,1 mm nozzle and Hop-Up 60 Shore bucking, we were able to get stable performance above 16m\/s above spring power. Even feeding with heavy weight 0,43 BBs on SEMI and AUTO was without any problem.\u003c\/span\u003e\u003c\/b\u003e\u003c\/p\u003e \u003cp\u003e\u003cb\u003e\u003cspan style=\"font-size: 18px; line-height: 106%; color: black;\"\u003e\u003cspan\u003e \u003c\/span\u003eFor best setting of inner barrel, we created new innovation on our Hop-Up chamber – the collet nut connection. It is placed in front of Hop-Up chamber. You will just install inner barrel with Hop-Up bucking into the chamber, seal it with clip lock and in the end, screw it together to Hop-Up chamber with collet nut (you will need 10 mm key). The collet nut is manufactured from aircraft dural EN AW 7075 and after screwing, it will seal inner barrel very strongly. There is no need force for installing collet nut, only easy force, otherwise the inner barrel will overturn in the Hop-Up chamber. Sign of best sealing is reduction of space in the collet.\u003c\/span\u003e\u003c\/b\u003e\u003c\/p\u003e \u003cp\u003e\u003cb\u003e\u003cspan style=\"font-size: 18px; line-height: 106%; color: black;\"\u003eThis Hop-Up chamber has best performance with our CNC gearbox V3, because these parts are constructed for best performance together.
