I'm a Newbie when it comes to airsoft so I was wondering if some folks who are more informed could help me out with finding the appropriate solution for a project I'm working on. Basically I'm looking for an inexpensive compact device for launching bbs at fairly close range remotely (not operated by a human). Power isn't a huge deal, but size and weight are - the smaller and lighter, the better. It won't be held by a person ever, so any handgrip or unecessary parts that's sole purpose is to improve handling or make it look more like a gun don't matter. The device also needs to be able to fire repeatidly without requiring cocking everytime. Any ideas what might be decent economical solutons? Looking to keep things fairly cheap.
