Hate to ask but can you provide pictures of the broken pieces? Is it possible to superglue then back together or use epoxy putty to remake the piece that sits on the pin?
I mentioned epoxy putty because it can dry very strong and at the same time be used as a sleeve or a screw port in shells for guns.
I will take a picture of it the next time I crack open the case. I can't find the tiny piece of plastic that broke off of the gear, so I'm not sure if it can be repaired.
On a similar note, can I (should I?) replace the barrel on my Rapidstrike with a brass barrel? I just ordered a bunch of Koosh Gen 3 darts and I heard the spiraling in the plastic tube on the RS can sometimes spin them out of control. My Rs also has 3x 180s and a BSUK wire and switch upgrade kit. Any thoughts?
