Removing orange tip

Warm water.
Hair dryer.
Heat gun.

Get the tip warm, and the glue should loosen up.

I tried the hammer and screw driver first :. Hopefully the hair dryer will work

It should, usually they are just glued on way too tight.

While I do not have experience with this rifle and its orange tip, I do have experience with orange tips that have been glued on extremely tight. I took the hair dryer, like woogie said, and let the hot air melt the glue for about ten minutes. Then I took a screw driver and tried to pry it off. If that does not work, try again. Take the hair dryer and let it's hot air melt the glue some more (around 10 minutes) and then try to get off the tip again. It took me quite some time, but just have some patience and it will all work out okay.

Good luck.

I know some people who, if the hair dryer doesn't work, put it in a pot of boiling water to melt the glue.
