Automatic, What gun?
A M38 Hardstock Automatic Air soft gun is smaller then a standard magazine. If you are looking to fit the gun inside a magazine Harper's Bazaar magazine is the thickest magazine.
It depends on the model.
No. The magazine hold the BB's. the Battery compartment holds the Battery
No. it has to be cocked each time.
No it is not possible
No. Spring must be cocked before each shot.
Safety is the responsibility of the shooter, not, the weapon. Weapons are mechanical devices and can fail.
