Metal high capacity airsoft magazine, precision made by Cyma. Open the lid on the top and pour in BB then turn the wheel on the bottom around 8 times to prime the mechanism. Each time you fire, the mag will automatically draw more BB from the reservoir. You can fire around 50 shots before needing to turn the mechanism's wheel again.
For super smooth feed apply an occasional drop of silicone oil and only use ultra grade airsoft pellets. Please note high-cap mags will not fire the last 20 to 30 BB as this is the distance between the top of the magazine and the winding wheel on the base. This is an exact clone of the Toyko Marui hi-cap mag and should work with all M14 series AEGs that are listed as TM compatible.
