With the long tax stamp wait times, I know a number of folks who built their SBR's initally as AR Pistols, defining the lower as a pistol on the 4473 and building with a pistol buffer tube or a regular tube, wrapped with paracord of rubber... keeping it far away from any unmounted butt stocks until the stamp comes in.
Personally I'm in the wait for it category, but that's me.
Yeah, build it first as an AR pistol - then (if you could find ammo) you can run it through its traces before spending the money on SBR paperwork (some SBR uppers need tweaking to run properly). Switching to a rifle buffer tube+stock when the tax stamp comes in is simple.
