I know there are lots of threads on this, some of them outdated at this point because the interpretation seems to have changed, so I apologize if I'm beating the dead horse, but here it goes.
I'm planning to build an AR SBR using a post FSA2013 lower in 5.56 with 11.5" barrel, do I need to use a HBAR (>.750 throughout profile) or can I use a standard government profile?
Thanks in advance for the help.
