JohnnyBGood's competitor 5 is a hammer powered gun that shoots grey clips from preloadable magazines. I was able to get ~30-45 ft out of the gun but you might get more or less. The gun is kind of fragile and isn't very reliable but is a very good concept gun and is also just plain cool!
My overall opinion on the gun is that it is good preforming and looking but was released too early and wasn't quite finished.
Range: 35 ft
Mag: grey clips removable mag
