need info for a letter to editor.
thanks

AFAIK- the rifle must be over 26" when fully extended.

IIRC the underfolding AKs are 25" +/- with the stock folded.

Open to correction as I'm not overly familiar.

"The term ''short-barreled rifle'' means a rifle having one or more barrels less than sixteen inches in length and any weapon made from a rifle (whether by alteration, modification, or otherwise) if such weapon, as modified, has an overall length of less than twenty-six inches."

28 USC 921(a)(8).

A Chinese AK underfolder is 25 3/4 inches long when the stock is folded.  A California state court held that the measurement is made with the stock folded, and that that such a firearm was a short barreled rifle under state law (which was virtually identical to the federal statute).  I believe that there is a Michigan Attorney General opinion reaching the same conclusion.  Nevertheless, that does not appear to be the case under federal law.  

It appears (and several non-authorative sources state) that the measurement is made with the stock extended under Federal law (otherwise underfolding AKs would not have been importable except as NFA items).  But I searched the U.S. Code, the Code of Federal Regulations, the Federal Register, and federal case law, and I didn't find anything.

Michigan = under 30 inches is a "pistol" (purchase permit required) and under 26" is an illegal SBR

thank you guys.
