When the NRA-branded iOS app NRA: Practice Range launched earlier this week (nearly on the one month anniversary of the Sandy Hook Elementary School Shooting that took place in Newtown Connecticut on December 14, 2012) it carried a rating of ages 4+.
Well it looks like Apple has reviewed the rating (no doubt after the game gained national attention by the mainstream media and some harsh criticism from several high profile politicians) and deemed that it was just too low. The game now carries a rating of ages 12+, meaning that your young children are no longer able to play the app for free. Apple's ratings descriptor for the game says that it contains "Frequent/Intense Realistic Violence." That descriptor is debatable given that the "realistic simulation" only contains target shooting.
