Custom HPA drum for the WE ak series. Custom made by me. Built from a cyma electric ak drum and a cut down we ak magazine Put a lot of time into developing these. They are fully serviceable, meaning if anything were to break, parts can individually be replaced. Everything is BRAND NEW, just has a few scuffs from building and testing. hopup app is scummy and won’t let you mark items as new unless you give them 10% I’d strongly recommend a high flowing regulator to get best results with this. Like a SFR would be perfect. Price is shipped NO TRADING
