FWIW: Check with MGT (machine gun tours) They might have factory SBR lowers in stock.
Up north here Bear Arms in Windsor has a few Factory SBR configurations. I was handling a SIG and a few other SBR's.

Looks like i found my next SBR. it's a nice light handling unit.
I like the factory vs. Form 1 SBR since i could if needed, sell it quicker as there needs no engraving of my info on it.
Yes i am aware there is a longer wait time if the rifle or Lower receiver is not in stock. However whats another 2 months ?
Call Alan @ MGT or Dave @ Bear Arms
