Bugs and glitches

More than half of the parts aren't accessible - for example, I can filter the manufacturer to 'surefire' in the muzzle devices, but they don't show up. This happens with more than half the manufacturers in ALL the products. Can't even get to many of the new parts they say are added. Also, when there are multiple 'pages' of items to scroll through, you are unable to go to the next page. I had a previous release of this app and while it was glitchy and would sometimes crash, at least I could access parts and filter through them as needed. This app was great but something happened after the latest parts dump. It wasn't an upgrade, it was basically a new app, and it's crap. Don't get this app til it's fixed.


It is a great app, could be better, more company's more parts more guns, but I think I speak for everyone when I say that every weapons app needs it, I love the break down of how you can work with all the parts and change all the colors to everything I don't rate a lot of things but this one caught my eye and definitely deserves the time to be put into it

Awesome tool

Not only is it fun just to build guns but if your going to do a build it really helps to be able to see what the finished product will look like
