I have two mini draco ak pistols that look exactly like this photo.
These weapons are classified as pistols, but shoot and use regular ak 47 magazines and ammo.
The case cited by the article is about a man who was arrested by a cop (in Tennessee, I think) who does not know the law and thinks the guy had an unregistered short barreled rifle. This should be a slam dunk case for the plaintiff.
The shoulder stock of an AK comes off with a couple of phillips-head bolts as I recall. I haven’t stripped one in a while, I think the last one I took down I installed a folding stock on it. Looks neat!
