Barrel and overall length

[Garys]

What are the MA and federal laws on barrel length and overall length? For example, would a rifle with a barrel length of 16 1/2 inches and an overall length of 36 inches be legal?

Or is it even that straight forward?

AFAIK,

For rifles its 16" barrel, 26" overall
Shotgun is 18" barrel, 26" overall

That's federal. Again, AFAIK, MA is the same.

Thanks. That seems to be the consensus from the various searches I did.
