I used to be heavy into paintball, I have a very well built, nitro fed AutoMag to shoot people with (plus a CO2 fed AutoMag, Tippman 98 Custom, Pro-Carbine, and Prolite, not to mention my just-failed-by-5psi autococking PGP project and AKA body minicocker project.)
Don't worry, I understand where you're coming from, but when I buy something that looks like a real firearm, it has to work like a real firearm.
