So I build the pistol lower first to avoid any potential legal trouble?
In this order
1. Build complete pistol lower.
2. Order upper parts.

Am I missing anything? Should I order a complete upper or does it matter?

Only order a complete upper if it is set up the way you want.

Build pistol lower first. Doesn't take long.

When you buy the lower don't you have to register it as a pistol if that's your intention?

stripped lowers should be checked off as "Other"

This , it's the best way as you can use the lower for a full build later, my FFL always does this for me.

DSG arms has some of the better quality uppers for quality prices.

You will see overall barrel length debated, but i think somewhere between 10.5-11.5 to be the sweet spot, i like 11.5 for little more dwell time, and that extra inch for some reason makes a significant difference with velocities.

one example, 409 for upper with BCG (no CH) have to sign in to see reduced prices.

10.5 vs 11.5 vs 14.5 velocities, this is from 2010 but info is interesting.
