简介：When a bird gun explodes, it is not a problem with the bird gun itself. It is mostly due to the use of inferior materials when making it, or because some craftsmen are impatient and eager for success, resulting in uneven thickness of the gun tube or lax welding. That's what caused the explosion. As long as the iron material is of high quality and the craftsmen are attentive, it is not difficult to solve the problem of the bird gun exploding.
