The Dream Army piston head was developed for the Tokyo Marui WE system because an imperfection of the stock were located. Most after-market products will have the same specification as the stock resulting slight wobbling and air leakage during blowback operation. Marui's original piston cup construction and WE-Tech's 1911 series can all have the air leakage issue resolved with this upgrade. This piston head is 100% CNC with the re-sized dimension, with anodized and Teflon coated surface treatment resulting smooth operation, superb air seal and maximum performance. Features: Re-sized with accurate dimensions to minimize air-loss. CNC Aluminum and teflon coated for smooth operation.
