This is superflous ,

Needs an update

Best gun building app, but needs more guns, more diverse attachments, more camos (sniper rifle camos on the other guns, and vice versa, maybe). The shooting range needs to be better, too. The app desperately needs an update. I've had this for a year or so now, and I haven't had a single update. Good app, but -1 star because it's getting stale.


One of the very best

I love this app it has only five guns but with enough imagination you can make plenty I turned a ak47 into an rpk and a m16 into an m60 desert eagles into Makarov's it isn't like other where it says you can make 1,000 guns but gives you 2 it says some 20 guns and gives five use your thought and build more guns you can make shotguns look like hunting rifles I say it is one of the very best gun builders on the app store it can call itself a gun builder

No hold Bars ,

App Developer needs to be updated.

I really like using this App to relieve stress, or to just have fun shooting things up. I am making my complaint through the review, for the developers of this app to work with IOS 11 and higher. I like to use the same shooting app when I have spare time to play the game, for 10 minuets, so please be kind, read this review, and update the app.
