SBR Engraving Legality

[AznTactical]

I recently saw a MK clone but with a SBR upper and noticed the owner had covered up his engravings as required by the NFA with a QR code. Are QR codes something new and the ATF handbook (chapters 6/7) haven't been updated? Per the ATF this engraving has to be "wholly unobstructed from plain view".

Do you have a picture. Hard to picture what you are talking about.

Could be in another spot on the lower? Magwell lip, under trigger gaurd, etc.
It is hard to imagine without pictures though.

You said he has a QR code on the upper. For AR style weapon, the lower must contain the NFA marking, and the marking is specified in terms of size and letters and content, so a QR code will not work. As @loveha mentioned, many are not adopting more conspicuous locations. We recommend that for military correct lowers, like a Colt or LMT, where you dont want to take away from the name brand. Under the trigger well is a great place.
