Viper, that depends.
If it's something like a M4, then yes. On my friend's it came with both a orange and a black tip, so he swapped them almost as soon as it was out of the box.
If it's something like a 1911, then probably not. The tip is glued on or like painted on AFAIK.
I'm probably wrong on the pistol part because I've never had a pistol with an orange tip save for crappy springers.
