Funny. Now that you mention it, I own a pre-2016 AG ban Ruger SR556. I was told at one point by an FFL in Mass that I could still sell this gun in Mass to a private party. If that is an accurate statement, and assuming that is still valid today, I would think that a rifle of this type would be in high demand in Mass and someone would be willing to pay well above market value to obtain it. Any thoughts on this? Any takers?
