Matrix 500 Round Metal Hi-cap Magazine for G3 Series Airsoft AEG

Description

Matrix 500rd Metal Hi-Cap Magazine for G3 Series Airsoft AEG.  These magazines have been in storage for several years and I've decided to start downsizing.  Good condition apart from some slight oxidation and chipped paint.
Features:
Metal Case
Polymer Internals
Winding Wheel Design
High Capacity Magazine Operation:
Find the trap door, usually located on the top of the magazine near the loading nozzle.
Open trap door and fill reservoir with high quality BBs.
Wind the wheel at the bottom of the magazine (notice the pitch and volume of the click).
Continue to wind wheel until pitch changes. Once the click gets louder, or begins to "double click," the magazine is fully wound.
Insert magazine into gun and fire. You may need to rewind the wheel during play.
