I am not a lawyer or BATF agent but I would think that --- YES , you have now got yourself a Sawed Off Rifle/Shotgun.
As the other posted stated ---- it is a Federal Statue for both barrel length and overall length.
Would you get busted for it ?? Maybe ---- but I would think a jury may see it as a broken gun.
Interesting question that ya posted.
Mike the Wolf --------- I'm with ya buddy as to the cleaning . takeing out the action etc. ----- just freaks me out that a few years ago , the Feds decided that IF You Have certain full-auto parts for a firearm you own , even if not installed on a firearm , then you are guilty of owning a full-auto firearm !!!!!
