I didn’t get
I didn’t get a Vice until after I built mine either.^ For the mechanically inclined, that's definitely possible. When I first started, I actually didn't even use a vise for the lower - I freehanded everything.
That lower is still chugging along today.
I also didn't pay much attention to the quality of parts: I never vetted their origin/manufacturers. I also never checked critical dimensions.
The gun runs just fine, but later on, after I knew better, I went back and re-did it.
It's definitely not that it can't be done without specialized tools: it's just that there definitely is a proper way.
