This is a semi-automatic airsoft gun that can transform into a pistol, PDW, and rifle without the need for gas or battery power. To create this versatile firearm, you'll need two essential components. Firstly, you will require an Airsoft Pocket Gun from ToyStar, available on eBay at https://www.ebay.com/itm/ToyStar-SPY-1-Pocket-Toy-Gun-Airsoft-Gel-Ball-Blaster-BK/193096730794?hash=item2cf57648aa:g:~T4AAOSwXsxc5GBO, which can be purchased for a mere 3.5 dollars if you're located in Korea. Secondly, you will need a PVC pipe with an outside diameter of 22mm and an inside diameter of 16mm. If you cannot obtain this specific size, consider printing or editing the provided file to accommodate your needs. The barrel and pins are constructed from PVC pipe, allowing for customization of the barrel length; however, it is crucial that the length of the pipe at the pin remains at 4cm. Feel free to add new components to enhance the functionality of this firearm. During assembly, using a heat gun on the holes will significantly simplify the process.
