This is the old project files plus STEP that I used to make the QBar. I'm basically out of the game despite this being my first project, due to needing to focus on many other things. This is a Ubar2 Ar15 lower receiver that accepts Desert Tech Qmag-53 quad stack mags. I have been unable to test the lower thoroughly besides handfeeding, but due to the nature of it being a lower, I feel comfortable releasing it to the public in this untested state. The license file is up to date, but the ReadMe is 2 years old and contains some outdated links and information. The magazine catch from KAK however, is tested to be long enough in order to work in the lower with a standard size mag release button. The bolt catch went through a few iterations to try to nail it down on being solidly triggered by the magazine, while still fitting in the upper receiver.

This project was dropped due to ADHD, but I had heard rumors that a newer Ubar 3 exists now, which accepts rifle length stocks properly. This explodes my microwave casserole, as now i will have to completely remake the front half that I did on the Ubar 2, and put it on the Ubar 3. I do not have this time to mess around with currently, as I don't even have the Ar15 parts that I used to make the build in the "renders" folder anymore. (The gun was cannibalized for 2 other projects)

The model is pretty boxy and primitive, I've always been a novice at this shit and combined with my undiagnosed-unmedicated ADHD at the time, was unable to put the time down to learn shit properly and actually try to make it look nice. There's no magwell funnel because I didn't feel like dedicating the time to it if I couldn't get it to function first. And then I sat on the model for 2 years.

Eventually I'll come back to it, but I can't pick it up until I'm ready. Maybe someone else can take the IPT and STEP and make their own revision to improve the lower to Ubar 3 standards.
