“Constructive Intent” as the BATFE has defined
If you are in posession of the parts AND a rifle in which those parts may be fitted, you are guilty of “constructive intent” and, for all purposes, posessing the actual machinegun. (M-16 fire control group and an AR-15).
Even if those parts are not fitted into the gun or the holes (AR-15) for the sear aren’t drilled.
My best hope for Palin's actions is that she might start tightening the leash on F Troop.
