A comparison. Good quality GBB handgun; well over 350$ or close to $400. You can find a real handgun for that.
Assault capable rifle? Around $1000.
If you want to know more; complete your profile (add your location) and go see local people.
Real gun parts? As said, they are better built if they fit.
Amount of real guns owned? Trust me, you are not close to what some of us have. So it does not matter.
Get out there and meet folks.
