More information about the MadBull Piston Factory Direct Replacement Program as they released a new video on this promo. For those who break their pistons due to high speed or high power setups, they can order direct from MadBull Airsoft online and they can select among the three options. The pistons cost US$1.50 each, which means that you can buy in larger quantities so you don't have to keep on repeating the purchase since you might lose out in shipping costs if you order just single pieces.

Watch the video below. More at the MadBull Airsoft website on this.
