But a rifle bbl still has to at least 16" "permanently". If you can screw that FS off with just a wrench leaving 14", ATF considers it a short bbl rifle requiring the $200 stamp.
BTW, I have a shop that can cut/thread/solder, I just need the flash suppressor now. What is the difference in the outer diameter of an AR bbl vs. a Mini 15 bbl?
