You buy an 80% lower which is not a firearm. You mill it to a stripped lower- it is now a firearm, and it is regulated. You want to get it engraved, like with a serial number, maybe a logo or design on the magwell. Is it legal to leave it with an engraver?
What defines barrel length? ie- a welded compensator or barrel extension is included in the barrel length, but the same thing threaded is not. Is a "pinned" compensator or flash suppressor included in barrel length? Any other attachment methods included?
A lot of posts refer to the AR10 type rifle as exempted. Is this true? Has any MSP opinion (letter, email, phone) been received supporting the exclusion of AR 10's from regulation/bans?
Along that last line, many posts refer to interchangeability of parts as a criteria for a copy, but from the GA's opinion in 2010, I don't think he mentions interchangeability, just similar functioning. (although it seems it would have been reasonable to use a percentage of interchangeable parts as a criteria). So how valid is the interchangeability test?
