RetroArms CNC hop-up chamber for AK

Hop-Up chamber for AK airsoft replicas. This new Hop-Up chamber is manufactured from aircraft dural EN AW 7075, what have steel-like strengh and weight of aluminum so it is best material for use. Chamber is milled on CNC milling machine and it also has protective anodizing of 0,005mm silver color.

For 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.
