I would like to build out an AR15 platform in .300 Blackout with a 12.5" barrel but I am really confused about the various legal issues and NFA requirements (tax stamp) ect. I don't really care about suppressors at this time and don't plan on using suppressors presently, so for this build that isn't an issue. Does anyone know of a good guide regarding this topic? I am a little confused between things like SBR and AR15 Pistol. How do they differ physically? How do they differ legally? What is required concerning NFA rules and regulations to build a 12.5" barrel AR15?
So many questions, so little time
I am in the process of building out my parts list and plans but would like to know what sort of legal hoops I can expect (or not expect) concerning NFA requirements so I can plan appropriately.
Thank you in advance!
