Today we have some more Android and iOS applications for you and this time we are looking at the best gun apps for 2012, which also includes weapons for Call of Duty: Modern Warfare 3.

First up for iOS users we have iGun Pro that lets users do everything from virtually reload, chamber, and fire their favourite guns. The application also teaches users about the history and specifications about the guns, which also include all the gun graphics to the interactive gun wall. Gun firing is ultra realistic with motion blur and smoke, and even the recoil can be adjusted. This free application has been getting rave reviews from users and can be found on the App Store.

The next iOS application we have for you is Gun Builder that allows users to virtually build their own gun and firing it. Guns are built from scratch from the massive library of gun parts and accessories, and you can even personalize it by engraving your own words or name on it. Users can take their gun down to the firing range with realistic sounds and animations. Gun Builder is available on the App Store for only £0.69/$0.99.

Next for iOS users is the free GunApp that is a gun/weapon simulator that features over 100 highly detailed animated guns ranging from M16s to nuclear weapons. Each weapon has detailed descriptions, and users can find out all the details about their favourite gun straight from Wikipedia, and Twitter integration allows you to tweet followers about the gun you are firing. Head over to the App Store to find out more.

For Android users we have MW3 Guns that lists all of the weapons featured in Call of Duty: Modern Warfare 3, which includes high quality images for each weapon along with realistic fire and reload sounds for each one, and in a future update there will be detailed information about each gun. This app can be downloaded free from Google Play.

Finally another free Android application we have for you is Call of Duty Black Ops Guns, which comes with all the weapons from the game including those from the Zombie section of the game and their authentic sounds. Head over to Google Play to find out more and to down load.
