Airsoft guns are a lot of fun, but they may not be in everyone’s budget. If you can’t afford one or just don’t want to part with the money, you can make one for about $15 total. It just takes 4 easy to find and cheap parts (assuming you have an air compressor.)
As great as the cheap factor is here, the best part about it is that it will fire hundreds of Airsoft BBs before you even need to reload. Say hello to my (cheap) little friend! You’ll need a plastic soda bottle, a quick release air compressor adapter, an air compressor blowgun, and a 7mm by 6-inch brake line. And of course an air supply. Not the soft rock band.
You could also use a portable air supply so you are untethered and free to hunt your prey. It seems simple enough to build, so it won’t take you long until you are unleashing hellfire on various objects and your enemies. I wouldn’t recommend shooting it at others, though, as Airsoft pellet hits can be pretty painful.
