Is there a such thing as a semi automatic spring airsoft gun?

technically yes, but really its a contradiction. you see most airsoft guns use springs (most) but when airsofters refer to a gun as a spring gun, they mean that the spring is powered by pulling back a handle or somehow cocking it (as with a shotgun or common spring pistol you may have used) any semiautomatic gun would have to be either electric (powered by a motor which compresses the spring for you) or gas powered (no spring involved)

yep 100%

wait how would that work? if you cock the gun which loads one bb... no not possible but if you want to find a gun check this website they often have specials like my friend got 2 bottles of bbs for buying $20 once so... http://www.airsoftatlanta.com/ shipping might be a bit more depending on where your from, this is a local shop for me...

No, but you can buy electic pistols(which suck btw). But the when you are cocking the gun you are loading the spring and also butting a new bb in the chamber

ummm no but i guess if you coc.ked the spring in time when you shot maybe or hold the trigger down and keep coc.king it
