Action Army's CNC-milled hop-up aluminum chambers ensure a perfect fit. The new hop-up system is equipped with innovative technology, whereby the setting is carried out using a rotary ring. Thanks to this property, the system can be adjusted particularly precisely. Furthermore, the hop-up chamber ensures a more reliable supply of BB's from the magazine.

The scope of delivery includes the complete hop-up chamber with small parts. The hop-up rubber and the inner barrel are reused from the previous system.

Only suitable for the Action Army AAP-01 GBB pistol series!
