Well, spring airsoft guns use an internal spring to fire the ammo and by auto you could be referring to either Auto Electric Guns (AEG's) which are quite popular and my personal favorite. AEG's use a rechargeable battery to operate a motor which fires the ammo that way.
Have fun.
You only have to cock it if it is a spring gun.
yes. u can mod the springer and replace the internals with electric parts or whatever. but u can buy one too: Tokyo Marui Gindan Glock 26 (G26) Semi Auto Spring Airsoft
50-500 depending on specifics
go back to the store where you buy that airsoft gun ang tell your problem to them.or ask someone that expert in airsoft
What is the difference between an auto injector and a pre filled syringe?
Yes. Gas revolvers are semi automatic, there are some spring pistols that must be re-cocked after each shot.
It depends on whether your trying to make it spring or electric. traditionally a VSS can be fired full auto. i would recommend finding a dragunov. i know there is one on airsoftgi.com for $150, although this is only a spring , or bolt action rifle. i recommend the dragunov because the clip and trigger area is the closest i know to a VSS that is made in airsoft. hope this helps!
No, there is not.
My 16 year old daughter keeps losing her keys? Is there a difference between a regular and auto locksmith?
yes
You can buy one from Tokyo Marui. not very well known, nor is it preferred. But modding a springer into an electric gun defeats the point. The "Tokyo Marui Gindan Glock 26 (G26) Semi Auto Spring Airsoft Gun" Is one of these. See related links for more info.
Nothing.
