RA-Tech announce their Custom GBB/HPA Drum Magazine for the WE AR Series. This means, they have modified a drum magazine where they tether it to an external HPA tank to power a WE Airsoft AR-style GBB. It works with their AR-15 Style Pistol based on the WE AR and comes with the M4 Forged Receiver 6061 and the RA-Tech Magnetic Locking NPAS Aluminium Loading Nozzle Set.
