It depends if you get one of the old ones, or one of the newer models.quite a lot of reviews say that the mini has many technical problems, and breaks a lot, does anyone know if this is true?
If you have an older one (cant remember the serial numbers) then you may need to get a mod done to the poppet inside the gun. If you buy new though, you shouldnt need anything like that done, it should rip straight out the box.
Mine did
