Oh man, I saw a pair of white ones at the thrift store in a $2.99 grab bag, so I picked them up to fiddle with. Just as you described, they TOTALLY SUCK at holding darts in.

The solution, clearly, is to tighten-up the tolerances of the back part of the barrel. Fingernail polish sounded like a great idea,  Or some thick enamel model paint, or anything that'll stick to plastic but dry to a non-sticky surface. Heck, I bet Elmer's Glue would work, but you probably have to rough-up the existing surface to make sure it doesn't just flake off after it dries.

So... how do you get it IN there? The only screws are the 4 holding the priming-handle cap in.

You just need a knife to get in there and push one of the side snap-tabs in while prying the backplate off. Then there's one central screw holding the Smart AIRbox in. Take that out, and voila, relatively easy access to the back side of the barrel interiors.
