That would be "In possession of something illegal", still not a felon. One is not a felon unless convicted.
This is what will happen. The feds are coming after everything we have. Death by a thousand papercuts. The fact what we have to constantly sue and go to court over the feds blatantly pissing on the 2A is just more proof of how little freedom we have.The part that scares me (and should scare anyone with working knowledge of semi-auto firearms) is that the definition of a machine gun can apply to any semi-auto firearm and especially to AR platforms. There have been several triggers and addons that can turn a standard AR platform firearm into a full auto without the 3rd hole for an auto sear or the recessed area in the lower receiver for said sear. If the ATF is allowed to continue down this rabbit hole they will deem all AR platform firearms as machineguns and subject to the NFA, then all semi-autos will follow.
