Matrix M3A1 Grease Gun AEG with two 520 round hi-cap magazines. Good used condition (see photos) Runs beautifully off a 7.4 lipo. Safety (the dust cover) occasionally sticks on the on position and takes a little jiggling of the trigger to deactivate it, but had never been an issue for me. Unfortunately the bottom of the grip that covers the battery housing is missing. If you have any questions please feel free to reach out! I am open to best offer!
