Yes it is legal...here's why. The BATF cateregorizes this as a non firearm. It is considered such because it is made to fire blanks only and can not be modified to fire live ammunition. While most paintball guns are more physically dangerous because they fire a projectile they too fall into the same category.

Go to the link below titled CONCEALED CARRY.
No, citizens in Indiana can apply for a gun permit and a CCW (concealed carry) permit at their local sherriff's office. You MUST HAVE A PERMIT to carry the weapon, however, or else it will be a crime.
Take the gun to a licensed seller, and get the address for a licensed seller in Indiana, have them ship the gun to Indiana.

No such thing as a blank gun. You can put blanks in a gun though.
Indiana does not require a permit to POSSESS ordinary firearms. It does require a permit to CARRY firearms CONCEALED. You apply for that permit through the Indiana State Police Website. This is a link to that website: http://www.in.gov/isp/2829.htm
No.
