  • i have a question why do people have the thing that the ammo shoots out of so long? does it help control it so it doesnt hurt you or backfire or does it give it more power? whats the deal haha? well try to please respond thankyou

  • If you are refering to the barrel, than the length is crucial to accuracy and velocity. Longer barrel = greater accuracy and velocity.

  • very nicegun whats the piston made out of?

  • Thanks,

    It's a simple, temporary, hot glue piston.

  • EVER Heard of teflon tape ????

  • i have a tutorial on how to cast lead bullets for your airgun if you want :)

  • I never said it wasn't.

  • i can agree to that but FPS is still speed not force

  • no...pressure is the force acting on the chamber...

    high vol. low pressure is normally the same as low vol. high pressure... You are thinking of FPS. (feet per second.)

  • what most people don't know is that pressure is the speed that the projectile comes out of the barrel you are better off having it at 120psi and having a massive air chamber to provide a lot of force but a high pressure gun is good for close distences

  • you know lead contamination can cause cancer and children defects?
