The Mangzhong MZ-01 is the first ever lever action blaster developed by a third party company that’s injection molded. The MZ-01 is small in size, and it’s got a soft blade in the front! 
The main body parts of this blaster is made out of either nylon or polycarbonate (for the clear one), and most internals are made out of nylon and POM with the plunger tube and barrel being aluminum, and don’t forget, the blade is made out of soft rubber so it’s definitely safe for your nerf games! 
The MZ-01 uses an inline magazine that takes 4+1 darts, it comes with 3 spring default, 1.3 for cowboy slinging, 1.4 for HVZ and 1.7 for better performance! It also comes with an extra extended barrel that allows you to install your bearing scar!
