Similar to the HOP UP PROWIN chamber, this one has been improved on some points.

The chamber is manufactured on the basis of a CNC machined aluminum block, the sides are more precise than the Prowin.

A passage of electrical wiring being wider compare to the Prowin for easier installation.

The parts of the settings are better machined for better adjustment and avoid the side spin. (Effect on the bb's that turns to the left or right)

Fully assembled, hop-up rubber, center ring and spring included.


Hop up chamber not compatible with an M-Nub of Flat nub (Unless you modify the hopup arm).
The hopup arm comes with a pre installed fixed nub.
