Extremely reliable gun, takes 7.4 lipo battery and can fire single or fully automatic. The spring in the brown magazine is broken, and the magazine doesn’t feed. It still fits in the mag well but the spring is broken - HOWEVER - The longer orange magazine feeds perfectly well. Aside from the brown magazine being non-functional, the gun itself and the orange magazine work magnificently and feed ammo very reliably. GUN INCLUDES 2 MAGAZINES
