It has been barely used i have recently shot it it it works like a charm! It is very durable, Hop-Up works and i have no problems with it overall. The fore grip, grip and stock are made out of a comfortable rubber. Also, the outer barrel and sights are full metal. It has a full metal gearbox and a 8.4v battery. It has 2 high-cap AK style magazines and has no feeding issues!
