Removing Orange Tip and It Shoot it at back yard, Illegal?
Removed Orange Tip and Place it at my Wall, Illegal?
Removed Orange Tip and play in the dessert, Illegal?
Is it illegal for playing at an airsoft field having removed orange tip?
It's legal in California for you to remove the orange tip as long as you're not selling or otherwise commercially transporting it.
Now, as for the legality of those activities... Playing in your back yard or in a desert is a bit iffy. You'd have to check your local airgun laws.
It is perfectly legal in California to remove the orange tip and display your gun on your wall and to play at an airsoft field having removed the orange tip.
There was a case recently where a person was traveling with his airsoft gun with removed orange tip in the front passenger seat of his pickup truck in California. He was charged with altering a replica firearm to appear more realistic, but the court ruled that airsoft guns were not replica guns but were instead bb guns, and that removing the orange tip was within his rights.
EDIT: That said, it is still illegal to brandish an airsoft gun, orange tip or not. Remember to always transport your guns in a case, bag, or in some way completely covered.
