Some nerf gun parts are glued, not solvent welded, but glued.

Does anyone know what glue nerf uses, and more importantly, how best to unglue?

Dip the part in boiling water and (with gloves or tools) work it back & forth gently. Keep dipping it and working it until the glue yields.

Hasbro has been using a couple of different methods for welding parts together.  Older blasters use "thermobond".  You can dip thermobonded parts in boiling water for up to 30 seconds to loosen the weld. Sometimes multiple dunkings are necessary as you work the pieces apart. Newer NiteFinder barrels are a classic example of this. Gloves are handy. DISCLAIMER: Boiling parts too long can deform the plastic beyond repair. Shorter more frequent dunkings work better.

 

Many newer blasters are solvent welded together. They cannot be boiled apart. Without getting into caustic chemicals, the best way to "unglue" them is to saw them apart.  I have had excellent luck with X-Acto Razor Saw accessories. They remove a minimum of material, and leave surfaces nearly ready to reassemble. The end-cap on the Buzz Bee S-n-i-p-e is a classic example. It must be sawed apart, then glued back together with epoxy weld.

 

Alternatively, there's the MTP kit for Dremel. It's a thin, inexpensive cutting wheel that can buzz through pesky solvent welds with a minimum of damage. You'll probably need a little epoxy weld to reassemble the pieces, but it's fast, clean, and non-toxic.

 

Good luck Azmorg !
