Customer Reviews

Entertainment and functionality

I could honestly lose myself in this app for extended periods of time. I love being able to see what I want to build before it's even begun.

incredible, but i have a suggestion

i love this app, it's absolutely amazing. but it would be even BETTER if you could have an option to pre-download all the parts when you're on wifi so it doesn't take so long when using cellular data

Gunstruction IMAGINATION!

I love the Gunstruction app. It allows my imagination for my firearms to be endless. I get an idea and then build it. I recommend this app to all my friends.
