No, it is not possible. The barrel is a part of the actual firing mechanism of this tank. Sorry. Should have asked that question before the build up.<div> I am going to use a Tamiya Leopard barrel for my Leo, Don't know what I'm going to do with my M1 just yet. Most likely will have to build something out of tube of different sizes. This has been the single biggest hurdle with these tanks for me. Decent recoil and flash for main gun.</div>
