Does it ready matter? Call it 29 and be done with it. The paperwork or the length will NEVER be looked at.

Also, I thought the length for NFA purposes was measured with any adjustable buttstocks unfolded and fully extended.
Otherwise... a regular title 1 sidefolder AK with a slant brake is only something like 24-25", which would make all sidefolder AKs SBRs (less than 26" OAL). Also, things like sidefolder Sig rifles (which are legal in MD).
So it should be quite easy to build an SBR to more than 29" OAL as measured with the buttstock fully extended.
For example, a 10.5" barrel with 1.5" muzzle device and a SOPMOD stock is 29.5" OAL with the buttstock all the way out.
And you don't want a 5.56 barrel shorter than 10.5" anyhow, trust me. I mean, it makes a fun toy, but that's about it.
I guess the law screws the 300BLK club a bit, but... If anybody tries to give you shit about it, just put a suppressor on it and you're golden.
Do the form 1 and put 29.5" on it.
