New trial granted in NFA case
Here's the ruling, as a small pdf file.
One gets the impression the court was a bit put off by ATF. (1) The raid was without any basis. Defendant had been an NFA dealer, and when he went out of that business, transferred an NFA gun to himself. At trial, the US Attorney conceded that was entirely legal. ATF either didn't notice the transfer, or claimed it was illegal in some other way. (2) The court cites an ATF advisory letter which clearly suggests that the count upon which defendant was convicted was without basis.
Basically, he had two shoulder stocks for pistols, and two pistols that would take them. One was a registered full auto pistol, for which the stocks were perfectly legal, and one was an ordinary semiauto pistol -- which, if a stock were attached to it, would be an NFA short barreled rifle. The court cites Thompson-Center for the proposition that possession of a set of components that could be made into a short barrelled rifle is not improper if it has "obvious utility" for also making non-NFA handguns or rifles. This is rather the flip side of that: the components had obvious utility for making a registered NFA firearm.
