Precision CNC Hop Up Chamber AK

Hop-Up chamber for AK airsoft replicas from RETROARMS.

This new Hop-Up chamber is manufactured from aircraft dural EN AW 7075, which has the steel-like strength and weight of aluminum so it is the best material for use. Chamber is milled on CNC milling machine and it also has protective anodizing silver color.

We 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 heavyweight 0.43 BBs on SEMI and AUTO was without any problem.

For the best setting of the inner barrel, we created new innovation on our Hop-Up chamber - the collet nut connection. It is placed in front of the Hop-Up chamber. You will just install the inner barrel with Hop-Up bucking into the chamber, seal it with clip lock and in the end, screw it together to a 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 a reduction of space in the collet.
This Hop-Up chamber has the best performance with our CNC gearbox V3 because these parts are constructed for best performance together. They are also constructed for screwing together, so they hold in straight line with inner barrel without any air leaks. You can also use this Hop-Up chamber with the common cast ZnAl gearbox.

The setting of Hop-Up is possible with setting lever in directions: front or back, as you need.
The hop-up spacer is not included.
