Retro Arms Hop-Up Chamber for M4

SKU: 0239 Categories: , , ,



Hop-Up chamber for M4/AR15 airsoft replicas.
This new Hop-Up chamber is manufactured from aircraft dural EN AW 7075, what have 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.

We build this Hop-Up chamber on results from testings, so this chamber is precise and custom-made constructed for best feeding and performance.

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.

The innovative adjustment system ensures precise setting of the hop-up and excellent control of the bb.

The hop-up chamber is delivered non-assembled – that means you have to put it together before use.
The kit contains all the necessary components.
