PDI Hop-Up Chamber APS2

The PDI hop-up chamber is designed for replicas with a scope, specifically the L96 or classic Maruzen APS2 models. This hop-up chamber is used to facilitate the installation of a classic AEG-type barrel and hop-up rubber without much hassle, thereby indefinitely increasing the upgrade possibilities of your replica. It is made from aluminum alloy and its operating system is significantly superior to the classic one. The barrel is secured with two hex screws, which we recommend not to tighten too much as they may damage the inner barrel, while the hop-up rubber is pressed by two parallel levers that allow fine adjustment of each part of the hop-up rubber. Thus, eliminating the need to align the hop-up rubber by rotating it or reshaping the pressing nub. The hop-up adjustment is done from inside the BB loading port, using two small hex screws.
