a compromise is for you to buy and supply the dealer/manufacturer with your short barrel of choice, have them register the lower and put it together and then sell it to you as a SBR. This is legal and done.
as currahee states, this is an option. You won't have to worry about having your engraving done, only the manufacturer or SOT would have to have engraving on there. The downside is that you don't have a gun to use while waiting for your Form 4.
Thanks for the replies, it is more complicated than I'd hoped.
i realize that I can engrave a lower, but I was hoping to make the process faster / simpler.
Maybe I should just buy a whole SBR, but it likely will not be the exact configure I want.
Not saying it is practical, but couldn't you pay for the lower and give the upper to the manufacture in order to complete the form 2, then submit the form 4 and have the manufacture remove the upper, hold onto it and give you the lower to use with a 16+ upper?
Exactly, Daniel Defense was the best as the SBR lower was the same cost as their lower. That was before the ATF cracked down on them, Noveske and others...so factory sbr's are sold complete.
A dealer must transfer a bare receiver as an "other" per ATF. No other option is correct unless it is built as a pistol or as a rifle.
