Very true, however one can't help but think of the documented incidents when someone used an NFA firearm for self-defense, such as in the case of Gary Fadden and Harry Beckwith. Every time seemed to result in a lengthy court battle where in every case the defendant was absolved of all wrong doing, yet they ALL stated basically stated it would have been a lot less painful if they had used a run of the mill shotgun or pistol instead. Allbeit they both used machine guns, however I am sure a SBR like a Krink or a Mk18 would probably look equally as evil to an uninformed jury. Just some food for thought, but personally as a civilian I think I would rather reach for my non-NFA weapon given the opportunity first rather than face a long unnecessary court battle.
