Looking to get a 10” or shorter 300 BLK barrel for my AR. I need to understand the technicality’s before I pull the trigger on this purchase (pun intended). What are the current rules as far as a pistol goes? Braces are out now? Only option is a smooth wall receiver extension? What are the challenges involved with registering it as an SBR with BATF? If I own other lowers that wear 16” or longer barrels and buttstocks, would having a less than 16” in my collection be an issue without registering one as SBR? Eventually want to add a can to this build, same tax stamp or another $200 for that? Thought I would ask you fine people for insight as I do my own homework on the interwebs. Maybe some of you have gone through this decision making process already.
Thanks for any advice you may have.
