GamePolitics.com said that Apple had reviewed the rating on a shooting app branded by the National Rifle Association, after widespread criticism that it was available with a rating of age “4+”.

With US gun control currently a hot topic, the game, called NRA: Practice Range, debuted on the App Store earlier this month.

After the title was met with some controversy, the age rating was lifted to “12+”.

While an NRA-backed shooting app is likely to raise eyebrows at the best of times, the launch, coming one month after the Sandy Hook elementary school shooting, certainly provoked a number of strong responses.

In addition to the game element, it is said to offer “2nd amendment newsfeeds, gun law information centres & educational materials you can access anywhere, anytime”.

It is free, with weapons upgrades linked to in-app purchases.

The title was developed by MEDL Mobile.
