Slow and cumbersome...

While the components themselves are designed well enough, the app as a whole is unbearably slow - a problem, it is worth noting, that plagues the website version as well. If you can put a basic rifle together in under half an hour - not any attachments, just a rifle with all the functional components - then I am in awe and you must teach me.
In addition, adding attachments is nigh impossible due to the clunky and uncooperative zoom and rotation features.
If these problems are systemic - that is to say, due to the app being a "terminal" and not containing any of the actual models or info, thereby being forced to draw it all from a data cloud - then it might be an idea to release a self-contained version of the app, file size be damned. If this is not the cause, then the developers have some colossal bugs to work out. Come on, folks: there is no excuse for an app this simple conceptually to be so shoddily-executed.
... Oh, and one more thing: please provide a method by which to shut off the seemingly randomized "Come and make them" banners that pop up at all hours. I already turned off push notifications, to no avail.

Long story short: a great idea, the execution of which is all but an utter failure.

G-wash about GUNSTRUCTION, v1.01
